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 provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to apply safe welding practices. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | 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. |
Context of and specific resources for 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. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with applying safe welding practices 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. |

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.
Required skills |
Look for evidence that confirms skills in: sourcing and interpreting safety-related information and Material Safety Data Sheets (MSDS) planning and sequencing operations identifying workplace risks and nonconformances reporting workplace risks and nonconformances checking and clarifying task-related information |
Required knowledge |
Look for evidence that confirms knowledge of: characteristics and properties of common metals and welding materials effect of gas and electrical welding operations on metals hazards and control measures associated with gas and electrical welding, including housekeeping welding safety practices and procedures effect of various treatments on a range of commonly used metals use and application of personal protective equipment |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
OH&S information | National Occupational Health and Safety Commission guidelines Organisational OH&S practices and procedures manuals Australian/New Zealand and ISO standards Company risk management policy Codes of practice Australian dangerous goods legislation Trade practices Occupational Health and Safety reporting requirements Weld procedures |

Other hazards | Fluxes Electro-magnetic radiation Electric shock Sparks Spatter Contaminated and coated metals Gas cylinder and electrical hazards Confined spaces Noise Chemical exposure Solvents Musculoskeletal, back and overuse injuries Vibration Dusts Heat stress Ultraviolet radiation Airborne pollutants Flammable gases Infrared radiation Thermal damage |
Manual handling techniques | Housekeeping practices Lifting weight limits Appropriate storage Use of lifting devices Appropriate training Hazardous materials storage standards and procedures |
Personal protective equipment | Respirators Ear muffs Protective clothing Gloves Boots Helmets Eye protection Face shields |
Procedures to control hazards | Substituting hazardous materials with safer materials Changing workplace design to eliminate hazards Modifying work practices to reduce exposure Using personal protective equipment Using adequate and appropriate ventilation |
Workplace safety measures | Shielding requirements Ventilation General and diluted Local exhaustion Use of personal protective equipment Checking equipment condition Equipment maintenance Correct operation of equipment Correct voltage and electrical connections Good posture Fire safety, plant and equipment isolation Communications with appropriate personnel |
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.
