Any aircraft component where braze welding is specified as either a fabrication or repair technique

Parent metal groups against which welding authorities are individually granted are:

Aluminium alloys

Magnesium alloys

Carbon steels and low alloy steels

Corrosion and heat resisting steels

Nickel alloys

Copper-based alloys

Titanium alloys

Welding equipment includes:

Fuel gases

Cylinders

Regulators

Hoses

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

safely applying braze welding skills defined in unit MEM05006C Perform brazing and/or silver soldering, to weld specified aircraft parent metal group materials or components to the standards specified by the relevant Regulator (CASA or the ADF)

applying welding principles (unit MEM05026C Apply welding principles) in the context of braze welding of aircraft components or materials

identifying braze weld requirements from applicable documentation

selecting and correctly using items of PPE applicable to braze welding of aircraft components.

Evidence is required of the ability to produce braze welds to required specifications consistently across the range of components that are being fabricated or repaired, while applying all relevant safety precautions. The ability to do this must be demonstrated through the production of the test pieces specified for the welding process and parent metal group in the CAAP 33-1(0) Aircraft manual welding: approvals and qualifications or RAAF Specification Engineering W5003 Welders – Qualification for Aircraft, Missile and Aerospace Fusion welding.
