- MUST BE ABLE TO PASS TAPE MEASUREMENT TEST AND ALSO READ BLUEPRINTS
Operate safety equipment and use safe work habits.
• Weld components in flat, vertical, or overhead positions.
• Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.
• Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
• Examine workpieces for defects and measure workpieces with straightedges or templates to ensure conformance with specifications.
• Recognize, set up, and operate hand and power tools common to the welding trade, such as shielded metal arc and gas metal arc welding equipment.
• Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys.
• Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding.
• Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals.
• Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.
• Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.
• Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.
• Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.
• Operate manual or semi-automatic welding equipment to fuse metal segments, using processes such as gas tungsten arc, gas
metal arc, flux-cored arc, plasma arc, shielded metal arc, resistance welding, and submerged arc welding.
• Mark or tag material with proper job number, piece marks, and other identifying marks as required.
Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc-cutting equipment.
• Remove rough spots from workpieces, using portable grinders, hand files, or scrapers.
• Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter.
• Preheat workpieces prior to welding or bending, using torches or heating furnaces.
