- Lay out, position, and secure 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.
- Cut workpiece, using powered saws, hand shears, or chipping knife.
- Melt lead bar, wire, or scrap to add lead to joint or to extrude melted scrap into reusable form.
- Install or repairs equipment, such as lead pipes, valves, floors, and tank linings.
- Observe tests on welded surfaces, such as hydrostatic, x-ray, and dimension tolerance to evaluate weld quality and conformance to specifications.
- Inspect grooves, angles, or gap allowances, using micrometer, caliper, and precision measuring instruments.
- Remove rough spots from workpiece, using portable grinder, hand file, or scraper.
- Welds components in flat, vertical, or overhead positions.
- Heat, form, and dress metal parts, using hand tools, torch, or arc welding equipment.
- Ignite torch and adjusts valves, amperage, or voltage to obtain desired flame or arc.
- Analyze engineering drawings and specifications to plan layout, assembly, and welding operations.
- Develop templates and other work aids to hold and align parts.
