Evidence Required

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 apply welding principles to meet the statutory and regulatory requirements for welding procedures

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently apply the skills and knowledge covered in this unit of competency in new and different workplace situations and contexts Critical aspects of assessment and evidence include

applying welding statutory and safety requirements to different welding jobs and environments

interpreting welding codes and symbols including symbols for type of weld weld size processing and finishing operations etc

applying appropriate pre and postheat treatment processes for a range of welded materials

setting up weld sequence and preparing materials in a logical manner for welding job

Context of and specific resources for assessment

This unit must be assessed in combination with one of the units satisfying the Australian Standard Certificates Welding to AS requires both theoretical knowledge and high practical skills The assessment process for the two units must be designed to identify consistent performance to the tandards the code and specifications across a range of materials and positions The assessment must also identify a workplace level of performance in terms of defect rates and weld failure rates It is recommended that assessment involve demonstrations of competency under both workshop and site conditions This means that the ideal assessment environment is either on the job or a combination of both on and off the job

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

Method of assessment

Typically an Engineering Tradesperson Fabrication and other tradespersons engaged in welding are required to apply welding principles and techniques across a range of jobs and specifications

A single assessment event is not appropriate On the job assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit

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 supervisors 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

This unit could also be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with applying welding principles to meet the statutory and regulatory requirements for welding procedures or other units requiring the exercise of the skills and knowledge covered by 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


Range Statement
