Building & Manufacturing

Welding

Fuse metal with heat, filler and skill - the backbone of fabrication.

What professionals do

Prepare and fit joints to drawings and weld symbols
Select processes, filler and parameters for the material
Run MIG, TIG, stick and flux-core welds to specification
Inspect welds visually for defects and discontinuities
Maintain equipment and gas systems
Follow hot-work, fume and confined-space safety rules

Typical work environments

Fabrication and job shopsPipeline and construction sitesShipyards and marine repairManufacturing plantsAerospace and precision shops

Equipment and systems

MIG, TIG and stick welding machinesFiller wire and electrodesShielding gas (argon, CO2 mixes)Angle grinders and prep toolsWelding PPE (hood, gloves, leathers)Weld gauges and inspection tools
