- 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.
- 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.
- 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.
- Fuel gas
The various qualities, hazards and applications of gaseous fuels, such as oxy-acetylene, oxy-gasoline, oxy-hydrogen and others.
- Interpret 2D plans
Interpret and understand plans and drawings in manufacturing processes which include representations in two dimensions.
- 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.
- Operate oxy-fuel welding torch
Operate a cutting torch fueled by oxyacetylene gas safely to perform welding processes on a workpiece.
- 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.
- Operate welding equipment
Use welding equipment to melt and join together pieces of metal or steel; wear protective eyewear during the working process.
- Ensure equipment availability
Ensure that the necessary equipment is provided, ready and available for use before start of procedures.
- Conform to health and safety regulations
Carry out all work in accordance with relevant environmental and health and safety legislation, risk assessment requirements and company policies. Take the necessary health and safety precautions during work including posture the body well, safely operate tools and machinery, and wear the right clothes and protection for the climate.
Identify operating problems, decide what to do about it and report accordingly.
- Perform metal active gas welding
Weld metal, mostly steel, workpieces together using active gas mixtures such as concotions of argon, carbon dioxide and oxygen.
- 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.
- 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 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.
- Align components
Align and lay out components in order to put them together correctly according to blueprints and technical plans.
- 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.
- 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.
- Smooth burred surfaces
Inspect and smooth burred surfaces of steel and metal parts.
- Wear appropriate protective gear
Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.
- 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.
- Monitor gauge
Oversee the data presented by a gauge concerning the measurement of pressure, temperature, thickness of a material, and others.
- 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.
- 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.
- Ensure correct metal temperature
Ensure the necessary, usually constant, temperature of processed metal workpieces during metal fabrication processes.
- 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.
