Welds or tack welds metal parts together, using spot welding gun or hand, electric, or gas welding equipment. Connects hoses from torch to tanks of oxygen and fuel gas, and turns valves to release mixture. Ignites torch and regulates flow of gas and air to obtain desired temperature, size, and color of flame. Preheats work pieces preparatory to welding or bending, using torch. Examines work piece for defects and measures work piece with straightedge or template to ensure conformance with specifications.

Climbs ladders or works on scaffolds to assemble structures. Signals crane operator to move large work pieces. Dismantles metal assemblies or cuts scrap metal, using thermal-cutting equipment such as flame-cutting torch or plasma-arc equipment. Positions and secures parts, using hoist, crane, wire and banding machine, or hand tools. Selects, positions, and secures torch, cutting tips, or welding rod, according to type, thickness, area, and desired temperature of metal. Guides and directs flame or electrodes on or across work piece to straighten, bend, melt, or build up metal. Fuses parts together, seals tension points, and adds metal to build up parts.
Hone your welding skills, train to read and comprehend blue prints, read a tape measure, pressure gauge, level, and square.
