Certified Pipe Welder

POSITION SUMMARY:

The Pipe Welder will participate in the installation or maintenance and inspection of HVAC, Utility and Process piping systems.

POSITION RESPONSIBILITIES:

• Regular attendance at assigned location; may include the A/Z fabrication facility or other project sites;
• Works on systems that include Heating Hot Water, Chilled Water, Steam, Condensate, Compressed Air, Process Fluids, Chemical, Fuel Oil, Gasses, and other related systems;
• Works with materials that include carbon steel, stainless steel, plastics, fiberglass, copper, (brazed, soft soldered and pro-press);
• Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding.
• Remove rough spots from work pieces, using portable grinders, hand files, or scrapers.
• Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc-cutting equipment.
• Weld pipe and components in flat, vertical, or overhead positions using open root butt weld, socket weld and/or fillet weld.
• 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.
• 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.
• Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.
• Examine work pieces for defects and measures work pieces with straightedges or templates to ensure conformance with specifications.
• Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreignmatter.
• Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.
• Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals.
• Fill holes, and increase the size of metal parts.
• Detect faulty operation of equipment or defective materials and notify supervisors.
• Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.
• Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.
• Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
• Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools.
• Clean or degrease parts, using wire brushes, portable grinders, or chemical baths.
• Mark or tag material with proper job number, piece marks, and other identifying marks as required.
• Position and secure work pieces, using hoists, cranes, wire, and banding machines or hand tools.
• Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.
• Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment such as flame-cutting torches or plasma-arc equipment.
• Preheat work pieces prior to welding or bending, using torches or heating furnaces.
• Hammer out bulges or bends in metal work pieces.
• Develop templates and models for welding projects, using mathematical calculations based on blueprint information.
• Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments.
• Cut, contour, and bevel metal plates and structural shapes to dimensions as specified by blueprints, layouts, work orders, and te
