Welding Services

Welding Services in Portland, Oregon

Boss PDX provides professional welding services across the Portland metro area, handling everything from structural steel connections on commercial buildings to custom ornamental railings on residential properties. As a licensed Oregon general contractor (CCB #232383), we bring the full weight of a construction company to every welding project, meaning your work is permitted correctly, engineered when required, and built to withstand the seismic demands that define construction in the Pacific Northwest.

Whether you need a steel beam welded into place during a remodel, a custom gate fabricated for your driveway, or emergency repair welding on a damaged structure, our certified welders work with MIG, TIG, and stick processes to match the right technique to every application.

Structural Steel Welding

Structural welding is the backbone of steel construction, and Portland's seismic classification makes it especially critical. Oregon falls within Seismic Design Categories C and D, which means welded steel connections on buildings, bridges, and other load-bearing structures must meet strict requirements under the Oregon Structural Specialty Code and the International Building Code. Boss PDX handles structural welding projects that require engineering oversight, special inspection, and compliance with AWS D1.1 (Structural Welding Code for Steel).

Our structural welding services include:

• Steel beam installation — carrying and welding W-flange beams, wide-flange columns, and HSS tube steel for load-bearing walls removed during remodels, additions, and tenant improvements
• Moment frame connections — seismic-rated welded connections engineered to flex rather than fracture during an earthquake, required on many Portland commercial and multi-family projects
• Column base plate welding — securing steel columns to concrete foundations with properly sized fillet and groove welds
• Steel bracing and gusset plates — lateral bracing systems welded to resist wind and seismic forces per engineered plans
• Mezzanine and platform fabrication — welded steel framing for interior mezzanines in warehouses, breweries, and industrial spaces throughout the Portland industrial districts

Every structural weld we produce is subject to visual inspection at minimum, and many projects in Portland require ultrasonic testing (UT) or magnetic particle inspection (MT) performed by independent third-party inspectors. We coordinate directly with your structural engineer and the local building department to ensure all welding procedures, welder qualifications, and inspection requirements are documented and satisfied before the work is covered.

If your project involves removing a load-bearing wall and installing a steel beam, we handle the full scope: temporary shoring, beam delivery, welding or bolting connections, and coordination with framing, electrical, and mechanical trades. Learn more about our steel construction capabilities on our metal buildings page.

Steel Beam Installation

Steel beam installation is one of the most common welding projects we perform in Portland, driven largely by the city's appetite for open-concept remodels in older homes and commercial tenant improvements that require wide spans without intermediate supports. Installing a steel beam is not simply a welding job. It is a structural modification that requires engineering, permitting, and careful execution.

Boss PDX manages the entire beam installation process: engineering coordination, permit applications through the City of Portland or surrounding jurisdictions, temporary shoring, steel procurement and rigging, field welding per engineered connection details, special inspection coordination, and final framing around the installed beam.

Residential beam installations in Portland typically involve W8 or W10 wide-flange beams spanning 12 to 20 feet. Commercial projects may require W14 or larger beams with moment connections. In both cases, welding must be performed by qualified welders using approved welding procedure specifications, and completed connections must pass inspection before being concealed.

Railing Fabrication and Installation

Custom metal railings are one of the most visible welding projects on any property, and Portland homeowners and businesses invest in them for both safety and aesthetics. Boss PDX fabricates and installs welded steel, stainless steel, and aluminum railings for stairs, decks, balconies, and commercial storefronts throughout the Portland metro area.

Stair Railings

Interior and exterior stair railings must meet Oregon Residential Specialty Code and commercial building code requirements for height (34 to 38 inches on stairs), graspability, baluster spacing (less than 4 inches), and structural loading (200-pound concentrated load on top rail). We fabricate railings that satisfy these requirements while matching the architectural style of your home or business, from clean modern flat bar designs to traditional scrollwork.

Deck and Balcony Railings

Portland's wet climate makes material selection critical for exterior railings. We build deck and balcony railings from hot-dip galvanized steel, powder-coated steel, stainless steel, and aluminum, depending on your budget and exposure conditions. Guard rails on decks and balconies 30 inches or more above grade require a minimum height of 36 inches (residential) or 42 inches (commercial) and must resist a 200-pound load applied in any direction at the top rail.

Commercial Railings and Handrails

ADA-compliant handrails for commercial properties require specific dimensions, extensions at the top and bottom of stair runs, and returns into walls or posts. We fabricate and install code-compliant commercial handrails for office buildings, restaurants, retail spaces, and multi-family housing across Portland. Our commercial contracting team handles the permitting, engineering coordination, and ADA compliance documentation.

Gate Fabrication and Installation

A welded steel gate provides security, privacy, and curb appeal that wood and vinyl alternatives simply cannot match. Boss PDX fabricates custom driveway gates, pedestrian gates, garden gates, and security gates for residential and commercial properties throughout Portland and surrounding communities.

Our gate fabrication services include:

• Driveway swing gates — single and double swing gates up to 20 feet wide, built from steel tube, flat bar, and solid stock
• Sliding and cantilever gates — ideal for sloped driveways common in Portland's West Hills, Southwest, and Northwest neighborhoods
• Pedestrian and garden gates — smaller gates matched to existing fencing, walls, or landscaping
• Security gates and enclosures — heavy-gauge steel gates for commercial properties, equipment yards, and parking areas
• Automated gate systems — electric operators, keypads, intercoms, and remote access for driveway and commercial gates

Every gate we build is designed for the specific opening, terrain, and use case. Portland's hilly terrain means many driveway gates require careful ground clearance planning, and our fabrication accounts for slope, swing arc, and drainage. Gates integrate with our fence installation and repair services for a complete perimeter system from a single contract.

Ornamental and Decorative Metalwork

Portland has a long tradition of decorative ironwork, visible in the historic districts of Northwest, the Pearl, Sellwood, and Irvington. Boss PDX fabricates custom ornamental metalwork that respects that tradition while using modern welding techniques and finishes that last decades in Portland's damp climate.

Our ornamental welding projects include window grilles, decorative panels and screens, custom brackets and corbels, fireplace surrounds, furniture frames, planters, trellises, arbors, and architectural accents. We work in mild steel, stainless steel, and aluminum, with finish options including powder coating, hot-dip galvanizing, patina finishes, and clear coats. TIG welding is our primary process for ornamental work because it produces clean, precise welds with minimal spatter. For heavier ornamental fabrication, we use MIG welding for speed and strength, then grind and finish the welds to a smooth profile.

Repair Welding

Boss PDX provides repair welding services for damaged, corroded, or failing steel structures and components across the Portland area. Repair welding requires assessment of the existing material, identification of the base metal, and selection of the correct filler metal and procedure to restore structural integrity.

Common repair welding projects we handle include:

• Cracked or broken stair railings and handrails
• Rusted-through gate frames, fence posts, and structural members
• Damaged steel beams, columns, and connections
• Failed welds on equipment mounts, brackets, and anchors
• Corrosion repair on fire escapes, balconies, and exterior steel structures
• Cast iron repair on historic Portland buildings and fixtures

Portland's wet climate accelerates corrosion on exposed steel, making repair welding a regular need. We assess whether repair is cost-effective or whether replacement is the better long-term investment, and give you an honest recommendation either way.

MIG, TIG, and Stick Welding Processes

Different welding applications require different processes, and Boss PDX welders are qualified in all three primary arc welding methods used in construction and fabrication.

MIG Welding (GMAW)

MIG welding uses a continuously fed wire electrode and shielding gas to produce fast, strong welds on mild steel, stainless steel, and aluminum. It is our workhorse process for structural steel, gate fabrication, and general construction welding. MIG welding is efficient for longer runs and thicker materials, making it ideal for production fabrication and field welding on construction sites.

TIG Welding (GTAW)

TIG welding uses a non-consumable tungsten electrode and separate filler rod to produce precise, clean welds with excellent control over heat input. We use TIG welding for ornamental work, stainless steel fabrication, thin-gauge materials, and any application where weld appearance matters. TIG is slower than MIG but produces superior results on visible joints and critical applications.

Stick Welding (SMAW)

Stick welding uses a consumable electrode coated in flux and requires no external shielding gas, making it the most versatile process for outdoor and field welding. We use stick welding for structural connections, repair welding, and field work where wind, rain, or confined access make other processes impractical. Stick welding with E7018 low-hydrogen electrodes is the standard for structural steel connections under AWS D1.1.

Mobile Welding Services

Boss PDX operates mobile welding rigs equipped to perform MIG, TIG, and stick welding on-site anywhere in the Portland metro area. Our mobile welding service is especially valuable for:

• Structural steel connections that must be welded in place on the building
• Gate and fence repairs that cannot be removed from the property
• Emergency repair welding on damaged structures
• Equipment and machinery repairs at industrial and commercial facilities
• Railing repairs on balconies, decks, and stairs that are attached to the structure

Our mobile rigs carry generators, welding machines, grinders, cutting equipment, and a selection of filler metals and electrodes to handle most common welding tasks in a single trip.

AWS Certifications and Welder Qualifications

Boss PDX employs welders qualified to American Welding Society (AWS) standards, including AWS D1.1 (Structural Welding Code for Steel) and AWS D1.6 (Structural Welding Code for Stainless Steel). Qualification testing verifies that each welder can produce sound welds in the positions, materials, and processes required by the project.

For projects requiring special inspection under the Oregon building code, we provide welder qualification records, welding procedure specifications (WPS), and procedure qualification records (PQR) to the structural engineer and special inspector. This documentation is a code requirement, and we maintain it as standard practice.

Portland Seismic Considerations for Welded Steel

Portland sits in a seismically active region, with the Cascadia Subduction Zone capable of producing a magnitude 9.0 earthquake. This geological reality directly affects how welded steel connections are designed and executed. The Oregon Structural Specialty Code assigns Seismic Design Categories that determine connection requirements, and most of Portland falls into categories requiring ductile welded connections designed to absorb seismic energy without brittle failure.

For welded moment frames and other seismic-force-resisting systems, this means prequalified connections per AISC 358, demand-critical welds requiring specific filler metals and preheat requirements, and mandatory ultrasonic testing. Boss PDX understands these requirements because we work with Portland structural engineers on seismic retrofit and new construction regularly. Seismic welding requirements exist because Portland will experience a major earthquake, and welded connections must perform when it happens.

Our work on retaining walls and foundation systems also intersects with seismic design, particularly where steel reinforcement and welded connections are required at grade beams, shear walls, and hold-down anchors.

Residential vs. Commercial Welding Applications

Residential Welding

Residential welding projects in Portland most commonly involve stair and deck railings, driveway gates, steel beam installations during remodels, decorative metalwork, and repair welding. Residential work uses lighter-gauge materials, emphasizes aesthetics alongside function, and falls under the Oregon Residential Specialty Code. Permits are required for structural welding but generally not for decorative or non-structural projects.

Commercial Welding

Commercial welding projects involve structural steel framing, storefront railings, security gates, equipment supports, and seismic retrofit work. These projects fall under the Oregon Structural Specialty Code, require special inspection for most structural welds, and involve complex permitting and engineering coordination. Boss PDX handles commercial welding as part of our full commercial general contracting services, integrating welding into the broader project schedule alongside other trades.

Welding Costs in Portland

Welding costs vary widely based on the type of work, materials, location, and complexity. The following ranges reflect typical Portland-area pricing as of 2026:

• Steel beam installation — $2,500 to $8,000 for a typical residential beam, including engineering, permits, shoring, beam, welding, and inspection. Larger beams and complex connections cost more.

Frequently Asked Questions

Do I need a permit for welding work on my property in Portland?

It depends on the scope. Structural welding, such as installing a steel beam or building a guardrail on an elevated deck, requires a building permit in Portland and most surrounding jurisdictions. Decorative metalwork, small repairs, and non-structural fabrication generally do not require permits. Boss PDX evaluates every project for permit requirements and handles the application process when permits are needed, so you never have to guess whether your project needs one.

What is the difference between MIG, TIG, and stick welding, and which one do you use?

MIG welding is fast and versatile, best for structural steel and general fabrication. TIG welding is slower but produces the cleanest welds, ideal for ornamental work and stainless steel. Stick welding works in any conditions including wind and rain, making it the go-to for outdoor structural connections. We select the process based on the material, joint design, position, and appearance requirements of each project. Some projects require multiple processes for different joints.

Can you weld stainless steel and aluminum, or only mild steel?

We weld all three. Mild steel (carbon steel) is the most common material in construction welding. Stainless steel is used for railings, kitchen equipment, and applications requiring corrosion resistance. Aluminum is lighter and corrosion-resistant, used for some railings, gates, and architectural elements. Each material requires different welding processes, filler metals, and techniques, and our welders are qualified in all three.

How long does a custom railing or gate project take from start to finish?

A typical custom railing project takes two to four weeks from initial measurement to completed installation, including design, fabrication, finishing (powder coating or paint), and installation. Custom gates take three to six weeks depending on size and complexity. Automated gate systems may add an additional week for operator installation and programming. We provide a project-specific timeline with every estimate so you know exactly what to expect.

Do you offer emergency or same-day welding repair services?

Yes. Our mobile welding rigs allow us to respond to urgent repair needs across the Portland metro area.
