RTE2205A Fabricate and repair metal or plastic structures

Modification History

Not applicable.

Unit Descriptor

This competency standard covers the requirements to undertake minor fabrication and repair of metal or plastic structures where the services of a specialist trades person is not necessary.

It requires the application of basic skills and knowledge to match materials against workplans, and select appropriate plant and equipment to carry out repairs and/or fabricate structures. The work involves the application of some judgement and discretion and would be carried out under supervision within enterprise guidelines.

Evidence Guide

What evidence is required to demonstrate competence for this standard as a whole? Competence in minor fabrication and repair requires evidence of the ability to effectively identify job requirements and select materials, tools and equipment to complete the job. It also requires the ability to identify and use jointing methods and safe and appropriate repair/fabrication techniques, and to clean up after operations. Evidence must be demonstrated in the employment of safe workplace and environmentally responsible practices. The skills and knowledge required to fabricate and repair metal or plastic structures must be transferable to a different work environment. For example, this could include fabrication and repair of different items and structures.
What specific knowledge is needed to achieve the performance criteria?	Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below: types of fabrication materials and their various applications range of metals and non-metal materials that may be used in fabrication and repair industry jointing/welding techniques and fabrication and repair methods OHS legislative requirements environmental codes of practice with regard to equipment operation and maintenance activities operating principles and operating methods for equipment various types of welders and respective functions environmental impacts and minimisation measures.
What specific skills are needed to achieve the performance criteria?	To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to: safely use welding and thermal cutting equipment demonstrate safe and environmentally responsible workplace practices read and interpret manufacturers specifications, work and maintenance plans, and MSDS effectively communicate information, interpret and apply task instructions, and maintain records and reports estimate and measure dimensions, and calculate volumes.
What processes should be applied to this competency standard? There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.
1. How can communication of ideas and information (2) be applied?	Information with regard to fabrication, repair, welding and cutting methods may be discussed with the supervisor and others in the work group.
2. How can information be collected, analysed and organised (2)?	Information with regard to equipment performance, faults and maintenance requirements may be detailed and monitored for analysis, and organised by records and reports.
3. How are activities planned and organised (2)?	Fabrication and repair tasks may be sequenced or carried out in conjunction with colleagues.
4. How can team work (2) be applied?	Team work may be applied in the communication and co-ordination of tasks to achieve specified work requirements.
5. How can the use of mathematical ideas and techniques (2) be applied?	Mathematics may be applied in the calculation and measurement of materials and resources used and volume dimensions.
6. How can problem-solving skills (2) be applied?	Malfunctions or breakdown will require arrangements for repair or replacement to meet work requirements.
7. How can the use of technology (2) be applied?	To communicate, maintain records, and troubleshoot performance problems.
Are there other competency standards that could be assessed with this one? This competency standard could be assessed on its own or in combination with other competencies relevant to the job function.
There is essential information about assessing this competency standard for consistent performance and where and how it may be assessed, in the Assessment Guidelines for this Training Package. All users of these competency standards must have access to the Assessment Guidelines. Further advice may also be sought from the relevant sector booklet.
