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.
