Assemble and weld metal parts on production line, using welding equipment, requiring only a limited knowledge of welding techniques

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 workpieces preparatory to welding or bending, using torch. Fills cavities or corrects malformation in lead parts and hammers out bulges and bends in metal workpieces. Examines workpiece for defects and measures workpiece with straightedge or template to ensure conformance with specifications. Climbs ladders or works on scaffolds to disassemble structures. Signals crane operator to move large workpieces. Dismantles metal assemblies or cuts scrap metal, using thermal-cutting equipment such as flame-cutting torch or plasma-arc equipment. Positions and secures workpiece, 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 workpiece to straighten, bend, melt, or build up metal. Fuses parts together, seals tension points, and adds metal to build up parts.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Production and Processing -- Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.

Operation and Control -- Controlling operations of equipment or systems. Equipment Selection -- Determining the kind of tools and equipment needed to do a job.

Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Arm-Hand Steadiness -- The ability to keep your hand and arm steady while moving your arm or while holding your arm and hand in one position. Near Vision -- The ability to see details at close range (within a few feet of the observer). Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Trunk Strength -- The ability to use your abdominal and lower back muscles to support part of the body repeatedly or continuously over time without 'giving out' or fatiguing. Dynamic Strength -- The ability to exert muscle force repeatedly or continuously over time. This involves muscular endurance and resistance to muscle fatigue. Dynamic Flexibility -- The ability to quickly and repeatedly bend, stretch, twist, or reach out with your body, arms, and/or legs. Extent Flexibility -- The ability to bend, stretch, twist, or reach with your body, arms, and/or legs. Wrist-Finger Speed -- The ability to make fast, simple, repeated movements of the fingers, hands, and wrists. Finger Dexterity -- The ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects.

Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems.
