• 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.
