Weld using manual metal arc welding process
Assessment tool
Version 1.0
Issue Date: April 2024
This unit applies to welds associated with heavy or light fabrication: fillet and butt welds in all positions on a range of materials that may include carbon steel or stainless steel. Weld quality would typically conform to Australian Standard 1554 General Purpose, American Bureau of Shipping (ABS) or equivalent.
This unit covers preparing materials, selecting and setting up the welding equipment, carrying out the manual metal arc welding (MMAW), and inspecting for and correcting defects, in a range of fabrication activities.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package | |
Overview of assessment requirements | A person who demonstrates competency in this unit must be able to prepare materials, select and set up the welding equipment, carry out manual metal arc welding and inspect for and correct defects, in a range of fabrication activities. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Context of assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. 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. |
Interdependent assessment | This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with welding using manual metal arc welding process or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | 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, supervisor's 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. |
Consistency of performance | 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. |
Required skills | Look for evidence that confirms skills in: |
identifying and interpreting 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 written job instructions, specifications, standard operating procedures and drawings | |
recording routine information related to MMAW onto proformas and standard workplace forms | |
following oral instructions | |
measurement skills relating to joint preparation and MMAW | |
Required knowledge | Look for evidence that confirms knowledge of: |
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 | |
use and application of personal protective equipment for MMAW | |

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.
The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here. The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable | |
Variable | Scope |
Welds | Welds would be fillet and butt in all positions |
Materials | Materials used would include carbon or stainless steel |
Prepared | Preparation of materials including preheating, setting up of jigs, fixtures, clamps, etc., joint preparation e.g. bevelling |
Equipment | AC or DC welding machines |
Distortion prevention measures | Include preheating, setting up of jigs, fixtures, clamps, etc. |
Rectified | Remedial action using thermal processes including oxy acetylene and air arc equipment Grinding devices may also be used |
Defects | 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.
