MEA431A Braze weld aircraft components

Modification History

New unit.

Unit Descriptor

This unit of competency covers the development of competency elements required to gain approval within the CASA or ADF regulatory systems to braze weld aircraft components. Individuals will be authorised to weld specific parent metal groups, as specified in CAAP 33-1(1) Aircraft manual welding: approvals and qualifications or RAAF Specification Engineering W5003 Welders – Qualification for Aircraft, Missile and Aerospace Fusion welding.

Application of the Unit

The unit requires application of the skills and knowledge of MEM05006C Perform brazing and/or silver soldering, to the brazing of applicable aircraft parent metal groups as specified by the Regulators.

Individuals who have attained this unit and the applicable approval from the relevant Regulator for the relevant parent metal groups will be able to perform braze repairs on aircraft components or fabricate components where the applicable welding process is specified as brazing.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

1	Prepare to perform repair or fabricate component using braze welding process	1.1	Materials or components to be brazed and the applicable parent metal group are identified in accordance with applicable data
1.2	Correct braze welding equipment and consumables are selected and safely set up in accordance with standard operating procedures
1.3	Component (or materials) is prepared for braze welding
1.4	Equipment is adjusted ready for the brazing process
2	Braze weld components	2.1	Braze welds are performed to the required standard in accordance with the applicable repair scheme or drawing
2.2	Completed welds are inspected for defects and any defects rectified
3	Complete documentation	3.1	Required documentation is completed in accordance with standard enterprise procedures

Required Skills and Knowledge

Look for evidence that confirms knowledge of: regulatory requirements applicable to aircraft welding standards applicable to aircraft welding the procedure for assessment of weld test pieces the use of braze welding in relation to specified aircraft parent metal groups Look for evidence that confirms skills in: 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 Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment	Test pieces must be completed and assessed in accordance with the regulatory requirements for the granting of aircraft braze welding approvals. Competency must be separately assessed for each parent metal group for which a braze welding authority is sought.
Critical aspects for assessment and evidence required to demonstrate competency in this unit	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.
Context of and specific resources for assessment	Test pieces specified for each parent metal group for which approval is sought may be completed in the workplace or a simulated workplace. The individual must be provided with all required equipment, consumables, PPE, materials and data/drawings relating to the test pieces that are required for the approvals being sought. Assessment of test pieces must be carried out in a testing facility that meets the requirements specified by the applicable Regulator.
Method of assessment	Assessment methods are specified 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.
