A CO2 Welder (also known as a MAG/MIG welder using carbon dioxide gas) specializes in joining metal components—primarily carbon steel and heavy structural steel—using a semi-automatic wire-feed
- Machine Setup &
- Calibration:
Adjust voltage, wire feed speed, torch angle, and CO2 gas flow rate based on metal thickness and joint type.
- Material Prep &
- Alignment:
Clean, bevel, measure, cut, and clamp steel plates, pipes, or structural parts before welding.
- Welding Execution: Lay clean, solid welds (fillet, butt, lap joints) on carbon steel and structural assemblies.
- Quality &
- Defect Inspection:
Check finished welds visually for porosity, cracks, or burn-through; chip away slag and grind down excess spatter.
- Blueprint Reading: Interpret welding symbols, technical drawings, and work instructions to meet exact specifications.
- Safety &
- Maintenance:
Wear required PPE (welding helmet, heavy gloves, leather apron), ensure proper ventilation, and perform routine maintenance on welding guns and nozzles.
