Overview

This unit of competency covers the preparation, positioning, fixing, and manual welding techniques associated with general trade level welding using manual metal arc welding (MMAW) equipment including the selection and set up of the equipment appropriate to both the material and the weld to be performed, carrying out the MMAW to prescribed standards, and examining for and correcting defects, in a range of welded fabrications.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each competency unit’s learning outcomes and performance criteria requirements, including the setting of project and work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

identifying and interpreting welding specifications including appropriate standards e.g. Australian Standard 1554 General Purpose, American Bureau of Shipping (ABS) or equivalent;
selecting and using appropriate tools and equipment;
using a variety of welding machines and electrodes;
identifying and rectifying weld defects;
applying techniques for distortion prevention and rectification;
cleaning welds;
reading and interpreting information on sketches, written job instructions, specifications, standard operating procedures and engineering drawings;
recording routine information including routine weld records related to MMAW onto proformas and standard workplace forms;
following oral instructions, and;
measurement skills relating to joint preparation and MMAW.

Students will also be expected to demonstrate the following knowledge:

material preparation;
joint preparations;
electrode classification;
causes of distortion for materials within the scope of this unit;
causes of defects and methods of rectification;
the relationships between amperage, electrode and material;
safe welding practices, and;
use and application of personal protective equipment for MMAW.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
