Assessment tool
Version 1.0
Issue Date: June 2024
This unit applies to all types of welding. It 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.
Band: A
Unit Weight: 2
This unit covers identifying material properties and selecting appropriate welding processes to achieve safe and effective welding outcomes.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 | A person who demonstrates competency in this unit must be able to select welding processes. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with selecting welding processes or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

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.
Required skills |
Look for evidence that confirms skills in: reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents planning and sequencing operations checking and clarifying task-related information |
Required knowledge |
Look for evidence that confirms knowledge of: hazards and control measures associated with welding practices, including housekeeping safe work practices and procedures properties and characteristics of commonly used metals and materials basic metallurgy principles information resources chemical content of fumes emitted by welding processes uses and purposes of various metals distortion prevention measures for various metals |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Characteristics | Tensile strength, grade, heat resistance, density |
Properties | Physical properties, flammable limits, melting point |
Basic metallurgical characteristics | Alloys and grades of metals and different types of electrodes |
Information | Steel suppliers handbooks, welding company materials, standard operating procedures, safety documentation |
Welding processes | Fusion: electric arc welding gas (oxy-fuel) welding thermit welding Pressure welding processes: resistance welding fire or forge welding friction welding explosive welding Low temperature processes: soldering brazing Other: ultrasonic welding electron beam welding |
Effects | Thermal expansion, heat affected zones, fume emissions, altered density, distortion |
Distortion prevention measures | Heat treatments, consolidations |
Processes for cleaning and weld preparation | Etching, grinding, arc gouging, thermal cutting, chemical additives, anti-corrosion treatments |
Safety requirements | 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.
