Welder

Lay out, fit, and fabricate metal components to assemble structural forms, such as machinery frames, bridge parts, and pressure vessels, using knowledge of welding techniques, metallurgy, and engineering requirements.

• Lays out, positions, and secures parts and assemblies according to specifications, using straightedge, combination square, calipers, and ruler.
• Tack-welds or welds components and assemblies, using electric, gas, arc, or other welding equipment.
• Cuts workpiece, using powered saws, hand shears, or chipping knife.
• Installs or repairs equipment.
• Observes tests on welded surfaces, to evaluate weld quality and conformance to specifications.
• Inspects grooves, angles, or gap allowances.
• Removes rough spots from workpiece, using portable grinder, hand file, or scraper.
• Welds components in flat, vertical, or overhead positions
• Heats, forms, and dresses metal parts, using hand tools, torch, or arc welding equipment.
• Ignites torch and adjusts valves, amperage, or voltage to obtain desired flame or arc.
