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 describes the essential skills and knowledge and their level required for this unit.
Knowledge and understanding of PE materials and pipeline components, as described in national standards, to recognise electrofusion welding compatibility, and suitability. Knowledge of detailed work instructions necessary to perform electrofusion welding, and the ability to implement within required parameters to attain required quality outcomes.
Knowledge as a basis for solving processing and material problems, including:
identify materials being used
identify compatibility of commercial operating systems
select electrofusion welding parameters for individual control units and fittings components
prepare electrofusion joint assemblies
set up and maintain safe working environment
operate control unit within required parameters
identify and rectify fault causes arising from machine operation and component variables
establish and maintain quality records
as relevant for the practical completion of work required.
Language, literacy and numeracy requirements
Read material which is sequenced for instructions, explanations, information or opinions.
Write short and simple messages about routine tasks or activities, or complete forms.
Use hands-on real-life materials and pictures/diagrams based on personal experience and prior knowledge.
Use several pieces of related mathematical information.
Read, write and speak whole numbers and money sums, recognise and interpret simple fractions, decimals and percentages, use simple data, grid references.
Use simple grammatical forms and vocabulary to give instructions, give explanations, ask questions and express viewpoints.
Clarify intended meaning by asking for repetition when listening, and varying speed and changing tone or emphasis when speaking.
Use strategies such as providing verbal and non-verbal feedback in order to show interest or attitude.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
Context
This competency unit includes the electrofusion welding of polyethylene (PE) pipeline components using calibrated output electrofusion control units. The end applications include pipelines used for transmission of gaseous and water based fluids.
It also includes the operation of all relevant ancillary equipment.
Specifications include national standards for materials (including but not limited to AS/NZS 4129, AS/NZS 4130, AS/NZS4131 and AS/NZS 4401), workplace specifications and instructions, and government codes and regulations.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
calibrated output electrofusion control units and pipe clamp supports
measurement devices, including timers, temperature probes, callipers and computer based output monitors
cleaning fluids, spray equipment and scrapers
relevant safety equipment
comprehensive work instructions.
Hazards
Typical hazards include
hazardous cleaning fluids
pipe material handling
heavy stationary and moving machinery
cutting and heating components.
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.
Typical process and product problems may include:
variable PE materials, and pipes as supplied
equipment malfunction or wear and tear
variable field site conditions.
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.
