Use hand-welding or flame-cutting equipment to weld or join metal components or to fill holes, indentations, or seams of fabricated metal products. Key Performance indicators (KPI) are as follows: welding components of the ship either repair or new builds are completed on time to specifications and within scope of the project 100% of the time, completes all required company training 100% of the time and follows all company policies and procedures 100% of the time.
Operate safety equipment and use safe work habits. • Weld components in flat, vertical, or overhead positions. • Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits. • Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding. • Detect faulty operation of equipment or defective materials and notify supervisors. • 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. • Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material. • Examine work pieces for defects and measure work pieces 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. • Lie out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers. • Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc cutting equipment. • Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations. • Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained. • Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys. • Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques. • Mark or tag material with proper job number, piece marks, and other identifying marks as required. • Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter. • Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals. • Remove rough spots from work pieces, using portable grinders, hand files, or scrapers. • Position and secure work pieces, using hoists, cranes, wire, and banding machines or hand tools. • Clean or degrease parts, using wire brushes, portable grinders, or chemical baths. • Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools. • Fill holes and increase the size of metal parts. • Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment such as flame-cutting torches or plasma-arc equipment. • Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments. • Gouge metals, using the air-arc gouging process. • Guide and direct flames or electrodes on or across work pieces to straighten, bend, melt, or build up metal. • Preheat work pieces prior to welding or bending, using torches or heating furnaces. • Use fire suppression methods in industrial emergencies. • Set up and use ladders and scaffolding as necessary to complete work. • Hammer out bulges or bends in metal work pieces.
