This unit of competency defines the skills and knowledge required to identify material properties and select appropriate welding processes that would typically conform to AS 1554 General Purpose and American Bureau of Shipping (ABS) or equivalent, to achieve safe and effective welding outcomes.

This unit applies to all types of welding and includes the identification of properties and characteristics of all commonly used metals, and selection of appropriate welding techniques to ensure integrity of materials is maintained during welding processes.

This unit can only be selected in conjunction with one or more of the following units:
  • MEM05015 Weld using manual metal arc welding process;
  • MEM05017 Weld using gas metal arc welding process;
  • MEM05019 Weld using gas tungsten arc welding process;
  • MEM05023 Weld using submerged arc welding process;
  • MEM05047 Weld using flux core arc welding process, and;
  • MEM05055 Weld using oxy fuel gas welding process.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Unit details

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


MEM13015 - Work safely and effectively in manufacturing and engineering

MEM16006 - Organise and communicate information


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: - following work instructions, standard operating procedures (SOPs) and safe work practices; - identifying properties of common used metals; - identifying potential contingencies and considering solutions; - identifying and selecting appropriate welding process and the effects of the welding process on materials, and; - identifying processes for cleaning and preparing metals and the role of contaminants in welding flaws.Students will also be expected to demonstrate the following knowledge: - safe welding practices and procedures and use of personal protective equipment (PPE); - properties and characteristics of commonly used metals and materials; - basic metallurgy principles associated with alloys and grades of metals; - uses and purposes of various metals; - distortion prevention measures for various metals; - different types of electrodes, and; - hazards associated with the use of chemicals and the fumes emitted by welding processes.
