Certification on pipe welding is required.

Job description

Tasks:

• Operate safety equipment and use safe work habits.

• Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.

• 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.

• Knowledge of preheating and post weld heat treatment of metals.

• 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.

• Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.

• Knowledge of various types of pipe welding including: GMAW, FCAW, GTAW carbon, GTAW low-alloy and stainless, GTAW nickel, GTAW followed by SMAW of chrome-moly, GTAW aluminum, GMAW aluminum plate and pipe.

• 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.

• Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.

• Mark or tag material with proper job number, piece marks, and other identifying marks as required.

• Preheat workpieces prior to welding or bending, using torches or heating furnaces.

• Develop templates and models for welding projects, using mathematical calculations based on blueprint information.

• Guide and direct flames or electrodes on or across workpieces to straighten, bend, melt, or build up metal.

• Detect faulty operation of equipment or defective materials and notify supervisors.

• Cut, contour, and bevel metal plates and structural shapes to dimensions as specified by blueprints, layouts, work orders, and templates, using powered saws, hand shears, or chipping knives.

• Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools.

• Hammer out bulges or bends in metal workpieces.

• Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment such as flame-cutting torches or plasma-arc equipment.

• Signal crane operators to move large workpieces.

• Use fire suppression methods in industrial emergencies.

• Estimate materials needed for production and manufacturing and maintain required stocks of materials.

• Have a working knowledge of QA/QC as it relates to welding.
