• 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.
• cuts workpiece, using powered saws, hand shears, or chipping knife.
• melts lead bar, wire, or scrap to add lead to joint or to extrude melted scrap into reusable form.
• installs or repairs equipment, such as lead pipes, valves, floors, and tank linings.
• observes tests on welded surfaces, such as hydrostatic, x-ray, and dimension tolerance to evaluate weld quality
and conformance to specifications
• inspects grooves, angles, or gap allowances, using micrometer, caliper, and precision measuring instruments.
• 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.
• analyzes engineering drawings and specifications to plan layout, assembly, and welding operations.
• develops templates and other work aids to hold and align parts.
• determines required equipment and welding method, applying knowledge of metallurgy, geometry, and welding
techniques.
