Overview

The position of Welder A reports directly to the Welding Supervisor and/or Project Manager for particular assigned project.

Responsibilities

  • Sets up and operates arc welding machine to weld together parts of fabricated metal products, as specified by blueprints, layouts, welding procedures, and operating charts
  • Welds flat, cylindrical or irregular parts that may be clamped, tack-welded or otherwise positioned
  • Visually examines welds for adherence to specifications
  • Grinds surfaces for interpass preparation or penetrant test
  • Adjusts machine setup to vary size, location and penetration of bead
  • Lays out, fits and tacks work pieces together
  • Preheats work piece, using hand torch or heating furnace
  • Removes surplus slag, flux and spatter, using brush, portable grinder and hand scraper
  • Connects cables from welding unit to obtain amperage, voltage slope and pulse
  • Strikes (forms) arc that generates heat to melt and deposit metal from electrode to work piece and joins edges of work piece
  • Manually guides electrode or gun along weld line, maintaining length or arc and speed of movement to form specified depth of fusion and bead, as judged from color of metal, sound of weld, and size of molten puddle
  • Welds in flat, horizontal, vertical or overhead positions
  • Examines weld for bead size and other specifications
  • Cleans or degreases weld joint or work piece, using wires brush, portable grinder or chemical bath
  • Prepares broken parts for welding by grooving or scarfing surfaces
  • Chips off excess weld, slag and spatter , using hand scraper or power chipper
  • Positions and clamps work pieces together or assembles them in jig or fixture
  • Operates other machine shop equipment to prepare components for welding
  • Welds short beads at points specified by layout, welding diagram or by fitter, along overlapping edges of metal parts to hold parts in place for final welding
  • Tack-welds, using hand submerged, or gas-shielded arc welding equipment
  • Welds metal parts, using gas welding equipment as specified by layout, welding diagram or work order
  • Selects torch tip, filler wire and flux according to charts and thickness and type of metal
  • Connects hoses from torch to regulator valves and cylinders of oxygen and fuel gas
  • Turns regulator valves to start flow of gases, lights torch and adjusts gas mixture and pressure to obtain flame of desired size and color based on knowledge of gas-welding techniques
  • In Arc cutter operations, cuts trims, or scarfs metal objects to dimensions, contour or bevel specified by blueprints, work order, or layout, using arc-cutting equipment
  • Selects carbon or metal coded carbon electrode, electric current, gas nozzle and gas pressure, according to thickness and type of metal, data on charts, or record of previous runs
  • Uses non-consumable tungsten electrode and gases, such as helium or carbon dioxide
  • Selects torch tip, gas pressures, speed of cut and allows for width of cut, according to thickness and type of metal as computer from charts
  • Installs torch tip and turns handle to start and adjust pressure of fuel gas
  • Directs flame on work piece to heat it to oxidizing temperature, as indicated by color of metal
  • Squeezes lever or trigger to release additional jet of oxygen that burns a path through metal
  • Guides flame along cutting line, observing cutting to judge angle, distance or torch and speed of movement
  • Lays out cutting lines, using rule square, compass or by tracing template
  • Moves or hauls or positions compressed gas cylinders near work area, drags weld leads from energy source to work area prior to beginning welding operations
  • Identify proper welding consumables and fluxes for a selected process
  • Responsible for care and cleanliness of their assigned equipment/workstation and/or area

Qualifications

High School diploma or general education degree (GED); or, 5+ years related experience and/or training; or equivalent combination of education and experience. This job requires the ability to read and interpret documents such as safety rules, operating and active experience in the following welding processes:   SMAW, SAW, FCAW, and others. Maintenance instructions and procedure manuals.  This job requires the ability to write routine reports and correspondence.  This job requires the ability to add, subtract, multiply and the ability to apply common sense understanding to carry out instructions in written, oral, pictorial or diagram form.  Will be required to pass welder certification or performance tests to meet certification standards of governmental agencies or professional and technical associations.  May be required to work while wearing respiratory protection, either air supplied or air purifying, depending upon atmospheric conditions and work location.  May be required to work in confined spaces, above ground in excess of fifty feet, outdoors in direct sunlight and in seasonal temperature extremes.  The ability to verbally communicate alarms or warnings clearly, concisely, loudly and quickly is essential.  Must be able to clearly and quickly hear or otherwise sense alarms or warning and take appropriate action, maintain equilibrium to prevent falling when moving, walking, standing, kneeling or crouching – particularly on narrow, uneven, irregular, slippery surfaces, going up or down ladders, stairs, scaffolding, ramps, poles or other objects using hands, arms, feet or legs.  Must be able to move about on hands and feet, bending the body downward and forward bending leg and spine – working in a bent over position.  Sensing physical attributes such as size, shape, temperature, texture or sharpness of an object by touching is required.  Must possess foot agility and dexterity – operating pedals, foot controls, kick bars and other similar tasks that require foot or toe motion.  Must be able to grasp, grip and/or apply pressure to an object with the fingers and palm, holding an object in the hand.  The ability to clearly and concisely perceive sounds, the ability to hear and understand detailed oral communication, the ability to hear warning signals and alarms given verbally and mechanically is essential.  Must be able to lift, raise or lower objects in a vertical direction, particularly heavy or bulky objects.  Must be able to move objects backwards, forward, in or out in a horizontal direction, particularly heavy or bulky objects.  Job will require pulling, exerting a steady backward, downward, upward or outward force against an object –jerking, plucking, wrenching, stretching, towing, drawing, dragging or tugging objects in a sustained motion.  Reaching, extending the hand(s) and/or arm(s) in any direction.  The ability to see, read and understand written communications; including directions, instructions and warning signs, to see and distinguish colors, to visually distinguish shapes and patterns, to accurately sense distances (depth perception), to accurately see objects and detect motion at wide angles (peripheral vision).  Bending the body downward and forward by bending the spine at the waist, using the lower extremities and back muscles and moving on foot, particularly for long distances.  Must be able to pass all pre-employment physicals and testing.
