Braziers operate various equipment and machinery such as torches, soldering irons, fluxes and welding machines in order to join two metal pieces together, by heating, melting and forming a metal filler inbetween them, often brass or copper. Brazing can join metals such as aluminum, silver, copper, gold, and nickel. Brazing is a similar process to soldering but requires higher temperatures.

- 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.
- 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.
- 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.
- Ensure equipment availability
Ensure that the necessary equipment is provided, ready and available for use before start of procedures.
- Apply brazing techniques
Apply and work with a variety of techniques in the process of brazing, such as torch brazing, braze welding and dip brazing.
- 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.
- 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.
- Monitor gauge
Oversee the data presented by a gauge concerning the measurement of pressure, temperature, thickness of a material, and others.
- Operate brazing equipment
Use equipment designed for brazing processes in order to melt and join together pieces of metal or steel.
- 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.
- Wear appropriate protective gear
Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.
- Apply flux
Apply a chemical cleaning agent, such as ammonium chloride, rosin, hydrochloric acid, zinc chloride, borax, and others, that removes the oxidation from metals being joined during soldering, brazing, and welding processes.
- 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.
- 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.
- Prepare pieces for joining
Prepare metal or other material workpieces for joining processes by cleaning the workpieces, checking their measurements with the technical plan and marking on the pieces where they'll be joined.
- Ensure correct metal temperature
Ensure the necessary, usually constant, temperature of processed metal workpieces during metal fabrication processes.
