Personality Type

  • Realistic / Conventional

Knowledge

  • Fuel gas

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

  • 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.

  • Flammable fluids

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

  • Metal thermal conductivity

    The property of metals to conduct heat.

  • Torch temperature for metal processes

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

Skills

  • 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.

  • 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.

  • 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, flux-cored arc welding, and others.

  • Join metals

    Join together pieces of metal using soldering and welding materials.

  • Ensure correct metal temperature

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

  • Smooth burred surfaces

    Inspect and smooth burred surfaces of steel and metal parts.

  • 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.

  • 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.

  • Interpret 3D plans

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

  • 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 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.

  • Operate welding equipment

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

  • Perform metal active gas welding

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

  • Align components

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

  • Interpret 2D plans

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

  • Operate oxy-fuel welding torch

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

  • Handle fuels

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