Description
distribution 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. Examine workpieces for defects and measure workpieces 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. Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers. 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. Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals. 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. Estimate materials needed for production and manufacturing and maintain required stocks of materials. Operate brazing and soldering equipment. Direct and coordinate activities of businesses or departments concerned with the production, pricing, sales, or distribution of products. Manage staff, preparing work schedules and assigning specific duties. Manage the movement of goods into and out of production facilities. Assist drafters in developing the structural design of products using drafting tools or computer-assisted design (CAD) or drafting equipment and software. Research, design, evaluate, install, operate, and maintain mechanical products, equipment, systems and processes to meet requirements, applying knowledge of engineering principles. Confer with engineers or other personnel to implement operating procedures, resolve system malfunctions, or provide technical information. Develop and test models of alternate designs and processing methods to assess feasibility, operating condition effects, possible new applications and necessity of modification. Specify system components or direct modification of products to ensure conformance with engineering design and performance specifications. Research and analyze customer design proposals, specifications, manuals, or other data to evaluate the feasibility, cost, or maintenance requirements of designs or applications. Provide feedback to design engineers on customer problems or needs. Design test control apparatus or equipment or develop procedures for testing products. Examine documents, materials, or products and monitor work processes to assess completeness, accuracy, and conformance to standards and specifications. Review documents, such as production schedules, work orders, or staffing tables, to determine personnel or materials requirements or material priorities. Confer with department supervisors or other personnel to assess progress and discuss needed changes. Revise production schedules when required due to design changes, labor or material shortages, backlogs, or other interruptions, collaborating with management, marketing, sales, production, or engineering. Confer with establishment personnel, vendors, or customers to coordinate production or shipping activities and to resolve complaints or eliminate delays. of supplies or parts to expedite flow of materials and meet production schedules. roof to install equipment Test electrical circuits or components for continuity, using electrical test equipment. Test pipe or tubing joints or connections for leaks, using pressure gauge or soap-and-water solution. Join pipes or tubing to equipment and to fuel, water, or refrigerant source, to form complete circuit. Install, connect, and adjust thermostats, humidistats and timers, using hand tools. using power saws or drills.
