Welds together metal components of products, as specified by layout, blueprints, diagram, work order, welding procedures, or oral instructions, using electric arc-welding equipment. Lays out, positions, aligns and fits together fabricated parts.

• Lay out, position, align, and fit together fabricated parts of structural metal products in shop according to blueprint and layout specifications, preparatory to welding or riveting.
• Plans sequence of operation, applying knowledge of geometry, effects of heat, and allowance for weld shrinkage, machining and thickness of metal.
• Sets up face block, jigs and fixtures.
• Locates and marks centerlines and reference points onto floor or face block and transposes them to work piece, using tape, chains, plumb bob, and squares.
• Moves parts into position, manually or by hoist or crane.
• Removes high spots and cuts bevels, using hand files, portable grinders and cutting torch. Straightens warped or bent parts.
• Positions or tightens braces, jacks, clamps, ropes, or bolt straps or bolt parts in positions for welding or riveting.
• Responsible for observing and complying with all safety and project rules, including wearing required personal safety equipment. Performs other duties and activities as required.
• Interpret engineering drawings and specifications to plan layout, assembly, and welding operations with precision.
• Lay out, position, and secure parts and assemblies using measuring tools such as straightedges, calipers, and rulers.
• Perform tack-welding and full welding on components in flat, vertical, horizontal, and overhead positions, including under pre-heat conditions.
• Cut and shape metal work pieces using powered oxy-fuel hand torch and other shop tools.
• Install and repair fabricated parts into assemblies, ensuring structural integrity and alignment.
• Remove surface imperfections using grinders, scrapers, and other finishing tools to meet quality standards.
• Select appropriate welding equipment and methods based on material properties and job requirements.
• Maintain a clean and safe work environment, including sweeping floors, removing hazards, and organizing tools.
• Manually guides electrode or gun along weld line, maintaining length of arc and speed of movement to form specified depth of fusion and bead, as judged from color of metal, sound of weld, and size of molten puddle.
• Obtains specified electrode and inserts electrode into portable holder or threads consumable electrode wire through portable welding gun.
• Connects cables from welding unit to obtain amperage, voltage, slope, and pulse, as specified by Welding Engineer.
• Starts power supply to produce electric current.
• Strikes arc which generates heat to make and deposit metal from electrode to work piece and join edges of work piece.
• Welds in flat, horizontal, vertical, or overhead positions.
• Examines weld for bead size and other specifications.
• May manually apply filler rod to supply weld metal.
• May clean or degrease weld joint or work piece, using wire brush, portable grinder, or chemical bath.
• May repair broken or cracked parts and fill holes. May prepare broken parts for welding by grooving or scarfing surfaces.
• May chip off excess weld, slag, and spatter, using hand scraper or power chipper. May preheat work piece, using hand torch or heating furnace.
• May position and clamp work pieces together or assemble them in jig or fixture. May tack assemblies together.
• May cut metal plates or structural shapes.
• May be designated according to type of equipment used as Welder, Carbon Arc (welding);
  Welder, Flux-Cored Arc (welding);
  Welder, Gas-Metal Arc (welding);
  Welder, Gas-Tungsten Arc (welding);
  Welder, Hand, Submerged Arc (welding);
  Welder, Plasma Arc (welding);
  Welder, Shielded-Metal Arc (welding).
• May operate other machine shop equipment to prepare components…
