This unit covers performing welding/fabrication inspection by selecting, conducting or verifying appropriate nondestructive tests, establishing and validating welding procedures, ensuring quality assurance is carried out, and monitoring procedures.

Unit details

Study level:
Vocational and further education (TAFE)
Unit code:


MEM05026C - Apply welding principles

MEM12023A - Perform engineering measurements


Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - obtaining, interpreting and applying relevant job instructions, design and weld specifications, codes, standards and procedures; - organising tests; - initiating and conducting weld tests; - obtaining and interpreting weld tests; - obtaining and interpreting weld design data; - verbally conveying, checking and clarifying information; - checking weld parameters for conformance to specifications; - documenting welding procedures; - preparing test reports; - recording movement of material through the workshop; - producing test pieces; - marking consumables for identification; - checking material for conformance to specifications; - using and storing welding consumables; - maintaining welding quality records; - checking welding records for conformance with welding quality requirements; - checking the form of the material to be welded for conformance with specifications; - using measurement skills for checking the dimensions of welded components, and; - performing relevant calculations. Students will also be expected to demonstrate the following knowledge: - hazards and control measures associated with welding/fabrication inspection; - safe work practices and procedures; - use and application of personal protective equipment; - types of non-destructive tests and their application; - welding procedures for the given weld; - tests/checks to be conducted; - arithmetic operations, formulae and calculations for testing welding/fabrications; - procedures for initiating the weld tests; - procedures for conducting a variety of non-destructive tests; - procedures for obtaining previous weld tests; - discrepancies between previous and current weld tests; - reasons for any identified discrepancies; - effects of testing procedures on test results; - procedures for verifying/amending previously established weld test procedures; - the parameters affecting the performance of the weld with respect to specifications; - variables affecting the performance of the weld; - tools, equipment and techniques necessary to check each variable; - procedures, tools, techniques and equipment necessary to check the form and dimensions of the welded components; - procedures for documenting welding procedures and preparing a weld test piece; - tools, equipment and techniques to carry out the prescribed tests; - procedures for initiating prescribed tests, obtaining test results, and reporting test result; - discrepancies between the test results and weld specifications; - action to be taken to return the welds produced to specification; - weld specifications; - methods of identifying weld materials; - reasons for correctly marking/identifying weld materials; - procedures for documenting/recording the movement of material through the workshop; - the reasons for documenting/recording the movement of material through the workshop, and; - procedures for transferring material test certification numbers.
