Unit of Competency MEM05017 - Weld using gas metal arc welding process
Description
Employability Skills
Learning Outcomes and Application This unit of competency has been developed for Engineering Tradesperson - Fabrication apprenticeship training and the recognition of trade-level skills in gas metal arc welding (GMAW) on heavy or light metal fabrications. It may also apply to other trade occupations requiring higher level GMAW welding skills.Weld quality would typically conform to Australian Standard 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: AUnit Weight: 4
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 or stainless steel

non-ferrous metals

alloys suitable for GMAW

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) r 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.
