Profession welder

Welders operate welding equipment in order to join metal workpieces together. They can use fusion welding processes based on different techniques and materials. They also perform simple visual inspection of welds.

Personality Type

• Realistic / Conventional

Knowledge

• Welding techniques

  The different methods of welding together pieces of metal using various equipment, such as oxygen-acetylene welding, gas metal arc welding and tungsten inert gas welding.

• Torch temperature for metal processes

  Ideal temperature of tools and machinery equiped with torches to perform various metal processing on workpieces.

• Quality standards

  The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.

• Metal thermal conductivity

  The property of metals to conduct heat.

• Fuel gas

  The various qualities, hazards and applications of gaseous fuels, such as oxy-acetylene, oxy-gasoline, oxy-hydrogen and others.

• Flammable fluids

  The behaviour of liquids and gases that represent a serious explosion and fire danger, and their appropriate handling systems and effective storage.

• Types of metal

  Qualities, specifications, applications and reactions to different fabricating processes of various types of metal, such as steel, aluminium, brass, copper and others.

Skills

• Interpret 3D plans

  Interpret and understand plans and drawings in manufacturing processes which include representations in three dimensions.

• Remove inadequate workpieces

  Evaluate which deficient processed workpieces do not meet the set-up standard and should be removed and sort the waste according to regulations.

• Perform metal inert gas welding

  Weld metal workpieces together using inert gasses or gas mixtures such as argon and helium. This technique is usually used for welding aluminium and other non-ferrous metals.

• Recognise signs of corrosion

  Recognise the symptoms of metal showing oxidation reactions with the environment resulting in rusting, copper pitting, stress cracking, and others, and estimate the rate of corrosion.

• Apply precision metalworking techniques

  Comply with precision standards specific to an organisation or product in metalworking, involved in processes such as engraving, precise cutting, welding.

• Remove processed workpiece

  Remove individual workpieces after processing, from the manufacturing machine or the machine tool. In case of a conveyor belt this involves quick, continuous movement.

• Align components

  Align and lay out components in order to put them together correctly according to blueprints and technical plans.

• Perform metal active gas welding

  Weld metal, mostly steel, workpieces together using active gas mixtures such as concotions of argon, carbon dioxide and oxygen.

• Interpret 2D plans

  Interpret and understand plans and drawings in manufacturing processes which include representations in two dimensions.

• Monitor gauge

  Oversee the data presented by a gauge concerning the measurement of pressure, temperature, thickness of a material, and others.

• Ensure correct metal temperature

  Ensure the necessary, usually constant, temperature of processed metal workpieces during metal fabrication processes.

• Select filler metal

  Select optimal metal used for metal joining purposes, such as zinc, lead or copper metals, specifically for welding, soldering or brazing practices.

• Perform tungsten inert gas welding

  Weld metal workpieces together by tungsten intert gas (TIG) welding. This arc welding process welds metal workpieces using the heat generated between an arc of electricity struck between a non-consumable tungsten metal electrode. Use an argon or helium inert gas to shield the weld from athmospheric contamination.

• Handle fuels

  Handle and store fuels and assess their potential risks and dangers.

• Join metals

  Join together pieces of metal using soldering and welding materials.

• Wear appropriate protective gear

  Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.

• Operate welding equipment

  Use welding equipment to melt and join together pieces of metal or steel; wear protective eyewear during the working process.

• Troubleshoot

  Identify operating problems, decide what to do about it and report accordingly.

• Operate oxy-fuel welding torch

  Operate a cutting torch fueled by oxyacetylene gas safely to perform welding processes on a workpiece.

• Ensure equipment availability

  Ensure that the necessary equipment is provided, ready and available for use before start of procedures.

• Perform test run

  Perform tests putting a system, machine, tool or other equipment through a series of actions under actual operating conditions in order to assess its reliability and suitability to realise its tasks, and adjust settings accordingly.

• Spot metal imperfections

  Observe and identify various kinds of imperfections in metal workpieces or finished products. Recognise the best fitted manner of fixing the problem, which could be caused by corrosion, rust, fractures, leaks, and other signs of wear.

• Smooth burred surfaces

  Inspect and smooth burred surfaces of steel and metal parts.

• Apply arc welding techniques

  Apply and work with a variety of techniques in the process of arc welding, such as shielded metal arc welding, gas metal arc welding, submerged arc welding and flux-cored arc welding.
