Version 1.0
Issue Date: April 2024


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

MEM05055 Weld using oxy fuel gas welding process

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

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Characteristics include the following:

tensile strength, grade, heat resistance and density

Properties include the following:

physical properties, flammable limits and melting point

Basic metallurgical characteristics include the following:

alloys and grades of metals and different types of electrodes

Information includes one (1) or more of the following:

steel suppliers’ handbooks

welding company materials

SOPs

safety documentation

Welding processes include one (1) or more of the following:

fusion – electric arc welding, gas (oxy-fuel) welding and thermit welding

pressure welding processes – resistance welding, fire or forge welding, friction welding and explosive welding

low temperature processes – soldering and brazing

other – ultrasonic welding and electron beam welding

Effects include one (1) or more of the following:

thermal expansion

heat affected zones

fume emissions

altered density

distortion

Distortion prevention measures include one (1) or more of the following:

heat treatments

consolidations

Processes for cleaning and weld preparation include one (1) or more of the following:

etching

grinding

arc gouging

thermal cutting

chemical additives

anti-corrosion treatments

Safety requirements include one (1) or more of the following:

dry and ventilated areas

in accordance with workplace procedures

location away from heat risks

location away from incompatible substances

requirements for hazardous substances

adequate signage and labelling

appropriate sealing

routine inspections

emergency procedures

regulatory notification requirements

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
