Welder

Lay out, fit, and fabricate metal components to assemble structural forms, such as machinery frames, bridge parts, and pressure vessels, using knowledge of welding techniques, metallurgy, and engineering requirements.

• Lays out, positions, and secures parts and assemblies according to specifications, using straightedge, combination square, calipers, and ruler.
• Tack-welds or welds components and assemblies, using electric, gas, arc, or other welding equipment.
• Cuts workpiece, using powered saws, hand shears, or chipping knife.
• Installs or repairs equipment.
• Observes tests on welded surfaces, to evaluate weld quality and conformance to specifications.
• Inspects grooves, angles, or gap allowances.
• Removes rough spots from workpiece, using portable grinder, hand file, or scraper.
• Welds components in flat, vertical, or overhead positions
• Heats, forms, and dresses metal parts, using hand tools, torch, or arc welding equipment.
• Ignites torch and adjusts valves, amperage, or voltage to obtain desired flame or arc.

• 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.
• 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. Written Comprehension -- The ability to read and understand information and ideas presented in writing.
• Extent Flexibility -- The ability to bend, stretch, twist, or reach with your body, arms, and/or legs.
• Near Vision -- The ability to see details at close range (within a few feet of the observer).
• Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations).
• Visualization -- The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged.
• Multi-limb Coordination -- The ability to coordinate two or more limbs (for example, two arms, two legs, or one leg and one arm) while sitting, standing, or lying down. It does not involve performing the activities while the whole body is in motion.
• Number Facility -- The ability to add, subtract, multiply, or divide quickly and correctly.
• Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions.
