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.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Prepare for joining | 1.1 Review work order and where required check with appropriate personnel. 1.2 Select appropriate repair, maintenance and personal protective equipment and check for operational effectiveness in line with manufacturer's recommendations. 1.3 Remove band saw blades from machinery. 1.4 Plan joining process in line with work order. |
2. Join or repair band saw blade | 2.1 Follow organisational safety procedures thoughout all maintenance and repair processes. 2.2 Obtain saw blank and cut to length or cut existing blade at weld defect. 2.3 Trim ends to obtain correct back alignment and pitch and/or shape to assist metal penetration. 2.4 Set up ends to specified tolerances in welder. 2.5 Apply weld to ensure metal penetrates through blade thickness and protect from accidental contact. 2.6 Grind surplus weld material from blade without burning or annealing metal. 2.7 Finish blade to eliminate bumps in blade surface. 2.8 Identify damaged blades or those with or sub-standard joins and dispose of these in line with environmental protection practices. 2.9 Package band saw for protection during return to service. 2.10 Identify routine processing and equipment faults and resolve or report to appropriate personnel. |
