This unit of competency has been developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in gas tungsten arc welding (GTAW) on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level GTAW welding skills.

Weld quality would typically conform to AS 1554 General Purpose and American Bureau of Shipping (ABS), or equivalent.

Where manual thermal processes associated with preparation, pre-heat and/or post-heat is required unit MEM05007 Perform manual heating and thermal cutting and unit MEM05008 Perform advanced manual thermal cutting, gouging and shaping, should also be selected as appropriate.

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

Band: A

Unit Weight: 4

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the 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.
Welds include the following:	fillet and butt welds carried out in all positions
Materials include one (1) or more of the following:	ferrous, including carbon steel or stainless steel non-ferrous metals aluminium and other materials suitable for GTAW welding
Preparation includes one (1) or more of the following:	pre-heating setting up of jigs, fixtures and clamps joint preparation (e.g. bevelling)
Distortion prevention measures include one (1) or more of the following:	pre-heating setting up of jigs fixtures and clamps
Rectify includes the use of one (1) or more of the following:	oxy acetylene air arc equipment grinding devices
Defects include one (1) or more of the following:	porosity slag inclusions discontinuities lack of penetration undercut

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.
