Welder

Field & Trades

Joins metal components with heat and pressure, and for structural work, has to prove it on a certification test before being allowed to do it on a real building.

What is a Welder?

A Welder joins metal components using heat, pressure, or both: most visibly, the structural steel connections that hold a building's frame together, but also metal decking, handrails, and miscellaneous steel throughout a project. For structural steel work governed by the American Welding Society's D1.1 Structural Welding Code (the code most commercial structural steel is built to), a welder has to pass a certification test for the specific process, material, and position they'll actually be welding in before they're allowed to perform that code work: a real, contractually enforced requirement, even though it isn't a government-issued license the way a journeyman electrician license is.

What they do

• Weld structural steel connections according to approved shop drawings
• Read welding symbols on drawings to determine the correct weld type, size, and location
• Pass (and periodically re-pass) certification tests for the specific process and position required by the job
• Inspect completed welds visually and prepare them for a certified welding inspector's review
• Set up and maintain welding equipment, including selecting the correct filler metal for the base material
• Work safely around fire hazards, fumes, and equipment operating at very high temperatures

A typical day

• 6:30 AMReview welding symbols on the day's drawings and set up equipment for the required process
• 7:00 AMWeld structural steel connections on the level currently being erected
• 10:30 AMStop for a certified welding inspector to review completed welds before the next connection is covered
• 1:00 PMRe-certify on a welding process the current scope of work requires but hasn't used recently
• 3:30 PMClean up and inspect equipment before the next day's work

Skills

Software

Education

Required:

High school diploma or equivalent, then trade school or a registered apprenticeship; for structural or pressure welding work, passing a certification test to the applicable welding code (most commonly AWS D1.1 for structural steel) for the specific process and position being performed, required by the code and the contract, not optional for that scope of work

Preferred:

Additional process-specific certifications as project scopes require them

Not necessary:

A four-year college degree; trade school or apprenticeship leading to code certification is the standard path
