What Gas Welding, Soldering And Brazing covers

Gas Welding, Soldering And Brazing in Welding Level 4 trains you to join and cut steel with a gas flame and to make brazed and soldered joints. It begins with communication in a welding workshop: principles and barriers, the flow of information, welding drawing interpretation, digital communication and basic costing. Gas welding covers health and safety standards, hazards, equipment and tools, material preparation, welding parameters, positions, joints, faults, defects and finishing. Gas cutting covers its tools, fuel gas and the cutting process. Brazing and soldering each cover tools, materials, parameters and process, and the unit ends with welding tool repair and preventive maintenance of fabrication machines.

Careers after Gas Welding, Soldering And Brazing

This unit prepares you for the benches and bays of metal workshops, where drawings, gas equipment and filler metals meet.

  • Fabrication workshops in Nairobi - read working drawings, prepare steel for gas welding and cutting, then weld in the required positions and joints, inspect the work for faults and defects, finish it and keep the work area clean and safe.
  • Metal repair shops in Nakuru - braze and solder repairs, choosing brazing materials and soldering materials for the metal and the job.
  • Self-employed welders in Kisumu - use basic costing to price a job, communicate with clients by phone and messaging and deliver finished gas-welded products.
  • Workshop maintenance sections in Eldoret - repair welding tools and carry out preventive maintenance on gas welding machines and other fabrication equipment.

Occupational health and safety standards and housekeeping apply in every one of these settings, and a welder who can also read drawings and cost a job is useful in all of them.
