Job brief

We are seeking a certified Welder to join our construction crew and contribute to major commercial and industrial building projects across the region. In this role, you will execute critical welding operations on structural steel assemblies, mechanical systems, and architectural metalwork while maintaining the highest standards of quality and safety. Working alongside ironworkers, pipefitters, and project supervisors, you will help bring complex construction designs to life through precise metal fabrication and welding expertise. If you take pride in creating strong, lasting welds that meet stringent inspection requirements, we want to hear from you.

Key highlights

Perform structural welding operations using MIG, TIG, stick, and flux-cored processes on carbon steel, stainless steel, and aluminum components according to AWS D1.1 specifications
Interpret welding symbols, blueprint dimensions, and WPS documents to determine proper joint preparation, welding sequence, and post-weld heat treatment requirements
Set up and calibrate welding equipment including Miller, Lincoln Electric, and ESAB power sources with appropriate voltage, amperage, and wire feed speed parameters
Conduct visual weld inspections using measuring devices and weld gauges to verify compliance with dimensional tolerances and surface finish requirements

What is a Welder?

A Welder is a skilled construction tradesperson who fuses metal materials together using various welding processes such as MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), stick welding, and flux-cored arc welding. Working with structural steel, aluminum, stainless steel, and specialized alloys, Welders interpret blueprints and welding symbols to create permanent joints that meet AWS (American Welding Society) standards and building code requirements. Their precision metalwork forms the backbone of construction projects, from high-rise building frames and bridge infrastructure to industrial piping systems and architectural metal features.

What does a Welder do?

A Welder begins each day by reviewing blueprints and welding procedure specifications (WPS), then sets up welding equipment including power sources, gas regulators, and electrode holders for specific joint configurations. They perform welding operations using SMAW, GMAW, GTAW, and FCAW processes, maintaining proper heat input and travel speed to achieve specified penetration and bead profiles. Throughout the day, they use measuring tools like calipers and welding gauges to ensure dimensional accuracy, grind and clean weld joints between passes, and conduct visual inspections following AWS D1.1 structural welding code standards before quality control personnel perform radiographic or ultrasonic testing.

Key responsibilities

Perform structural welding operations using MIG, TIG, stick, and flux-cored processes on carbon steel, stainless steel, and aluminum components according to AWS D1.1 specifications
Interpret welding symbols, blueprint dimensions, and WPS documents to determine proper joint preparation, welding sequence, and post-weld heat treatment requirements
Set up and calibrate welding equipment including Miller, Lincoln Electric, and ESAB power sources with appropriate voltage, amperage, and wire feed speed parameters
Execute fit-up procedures using clamps, jigs, and alignment tools to maintain proper gap, root opening, and joint geometry before welding operations
Conduct visual weld inspections using measuring devices and weld gauges to verify compliance with dimensional tolerances and surface finish requirements
Perform gouging, grinding, and flame cutting operations to prepare base metals and remove defective welds for repair procedures
Maintain welding consumables inventory including electrodes, filler wire, shielding gases, and flux materials while following proper storage protocols
Complete daily welding logs and quality documentation for traceability and compliance with project specifications and building inspector requirements

Requirements and skills

AWS D1.1 Structural Welding certification or ability to pass welding qualification tests in multiple positions (1G, 2G, 3G, 4G) within 30 days

Ability to read and interpret construction blueprints, welding symbols per AWS A2.4 standard, and technical specifications for structural steel assemblies
Proficiency with welding equipment setup including power source parameter adjustment, gas flow regulation, and electrode/wire selection for various base materials
Physical capability to work in confined spaces, elevated positions, and outdoor environments while maintaining welding quality in all weather conditions
OSHA 30-Hour Construction certification and knowledge of hot work permit procedures, fire watch protocols, and respiratory protection requirements
Experience with plasma cutting, oxy-fuel cutting, and carbon arc gouging equipment for metal preparation and repair operations
Valid driver's license and reliable transportation to travel between job sites within a 75-mile radius of the home office

FAQs

What does a Welder do in construction projects?

A Welder in construction creates permanent metal joints that form the structural framework of buildings, bridges, and industrial facilities. They use various welding processes like MIG, TIG, and stick welding to join steel beams, columns, and plates according to engineering blueprints and AWS welding codes. Construction Welders work on everything from high-rise building frames to pipeline installations, ensuring each weld meets stringent quality and safety standards through proper technique and post-weld inspection procedures.

What certifications do construction Welders need?

Most construction Welders need AWS (American Welding Society) certifications, particularly AWS D1.1 Structural Welding certification which covers welding procedures for building construction. Many employers also require OSHA 30-Hour Construction safety certification and may prefer additional credentials like AWS D1.5 for bridge welding or ASME Section IX for pressure vessel work. Welders must pass practical welding tests in multiple positions (flat, horizontal, vertical, overhead) and demonstrate proficiency with different welding processes to maintain their certifications.

What career advancement opportunities exist for construction Welders?

Experienced construction Welders can advance to specialized roles such as Certified Welding Inspector (CWI), Welding Supervisor, or Lead Welder positions that involve training junior welders and overseeing welding quality control. Some transition into welding engineering, fabrication shop management, or start their own welding contracting businesses. Welders with additional certifications in underwater welding, pipeline welding, or aerospace welding can access higher-paying specialized markets, with senior positions often earning $65,000-$90,000 annually plus overtime opportunities.

Why are skilled Welders important in construction?

Skilled Welders are critical to construction safety and structural integrity because welded joints must withstand enormous loads, environmental stresses, and seismic forces over decades of building use. Poor welding can lead to catastrophic structural failures, making certified Welders essential for creating reliable connections in steel-framed buildings, bridges, and industrial structures. Their expertise ensures compliance with building codes and engineering specifications, while their precision work directly impacts project timelines and overall construction quality standards.
