Fabricate and assemble structural metal products, such as frameworks or shells for machinery, ovens, tanks, and stacks, and metal parts for buildings and bridges, according to job order or blueprints.

Develops layout and plans sequence of operations for fabricating and assembling structural metal products, applying trigonometry and knowledge of metal. Locates and marks bending and cutting lines onto workpiece, allowing for stock thickness and machine and welding shrinkage. Hammers, chips, and grinds workpiece to cut, bend, and straighten metal. Verifies conformance of workpiece to specifications, using square, ruler, and measuring tape. Preheats workpieces to render them malleable, using hand torch or furnace. Positions, aligns, fits, and welds together parts, using jigs, welding torch, and hand tools. Sets up and operates fabricating machines, such as brakes, rolls, shears, flame cutters, and drill presses. Sets up and operates machine tools associated with fabricating shops, such as radial drill, end mill, and edge planer. Designs and constructs templates and fixtures, using hand tools.

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Building and Construction -- Knowledge of materials, methods, and the tools involved in the construction or repair of houses, buildings, or other structures such as highways and roads. Design -- Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models. Production and Processing -- Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods. Engineering and Technology -- Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services.

Operation and Control -- Controlling operations of equipment or systems. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Mathematics -- Using mathematics to solve problems. Reading Comprehension -- Understanding written sentences and paragraphs in work related documents. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Operations Analysis -- Analyzing needs and product requirements to create a design. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly.

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. Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Static Strength -- The ability to exert maximum muscle force to lift, push, pull, or carry objects. Multilimb 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. Visualization -- The ability to imagine how something will look after it is moved around or when its parts are moved or rearranged. Number Facility -- The ability to add, subtract, multiply, or divide quickly and correctly. Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem.

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. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Making Decisions and Solving Problems -- Analyzing information and evaluating results to choose the best solution and solve problems. Estimating the Quantifiable Characteristics of Products, Events, or Information -- Estimating sizes, distances, and quantities; or determining time, costs, resources, or materials needed to perform a work activity.
