Overview

This unit of competency was developed for engineering fabrication trade training and the recognition of trade skills in selecting welding processes.
It defines the skills and knowledge required to identify basic material properties and select appropriate welding processes to produce welds that conform to AS 1554 General Purpose (GP) and American Bureau of Shipping (ABS) or equivalent as defined by the unit in conjunction with its prerequisites.
The unit includes all welding processes within the scope of AS 1554 GP and the identification of basic properties and characteristics of all commonly welded metals to the extent required to inform the selection of appropriate welding processes.
This unit must be selected in combination with one or more of the following units:

  • MEM05090 Weld using manual metal arc welding process
  • MEM05091 Weld using gas metal arc welding process
  • MEM05092 Weld using gas tungsten arc welding process
  • MEM05093 Weld using submerged arc welding process
  • MEM05096 Weld using flux core arc welding process
  • MEM05097 Weld using oxy fuel gas welding process.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit's learning outcomes & 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:

  • follow work instructions, standard operating procedures (SOPs) and safe work practices
  • match type and grade of base material from manufacturer’s marks or documentation to specifications on at least two occasions
  • identify properties of commonly used metals and alloys using reference information contained in materials and equipment suppliers * handbooks, enterprise documentation or SOPs
  • identify potential welding related contingencies and consider solutions
  • identify and select appropriate welding process, considering process effects on materials on at least two occasions.
    Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Students will also be expected to demonstrate the following knowledge:

  • safe welding practices and procedures and use of personal protective equipment (PPE)
  • hazards associated with the use of chemicals and the fumes emitted by welding processes
  • properties and characteristics of common metals and materials used in welding including tensile strength, grade, heat resistance, density, physical properties, flammable limits and melting point to the extent required to inform selection of an appropriate welding process
  • basic metallurgy principles associated with the effects of heat on alloys and grades of metals
  • common metal and alloying elements used in welding
  • common carbon steels, alloy steels and stainless steel grades used in welding
  • uses and purposes of various metals and alloys
  • distortion prevention measures for various metals
  • different types of electrodes.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by Victoria University and/or via the Victoria University e-learning system.
