2. Prepare tips | 2.1. Saw is cleaned of foreign matter and checked for defects 2.2. Tips requiring replacement are measured and compared to manufacturer's tolerances, checked and marked 2.3. Saw teeth are prepared to provide a suitable surface for replacement 2.4. Saw and tip surfaces are cleaned to provide a good contact surface for brazing or silver soldering |
3. Replace tips | 3.1. Saw is set up in welding jig in line with manufacturer's instructions 3.2. Brazing material and technique is selected suitable for the material, application and the control of heat 3.3. Replacement tip is selected to meet application specifications and welded into position with tolerances checked 3.4. Trial weld of one tip is conducted and adjusted where necessary, to confirm weld pressure, current temperature and anneal settings against specifications 3.5. Trial weld is included in replacement process or where sub-standard, material is segregated and disposed of in line with site procedures and environmental requirements 3.6. Manual or automatic feeds are set in line with the number of tips to be welded 3.7. Tip replacement is carried out regularly, checking and adjusting annealing process temperatures and current to ensure staying within the specified range 3.8. Tips damaged in the replacement process are repaired/sent for repair and tips that cannot be repaired are disposed of 3.9. Surplus brazing material is removed from saw surfaces and tip tolerances checked against specifications 3.10. Replacement process and equipment faults are investigated, recorded and reported in line with site requirements |

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 provide evidence that they can safely and efficiently replace stellite tips within organisational requirements |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The evidence required to demonstrate competency in this unit must be relevant to, and satisfy, all of the requirements of the elements of this unit and include demonstration of: following applicable Commonwealth, State or Territory legislative and regulatory requirements and codes of practice relevant to replacing stellite tips following organisational policies and procedures relevant to replacing stellite tips replacing stellite tips in line with the work order and within prescribed organisational requirements removing and replacing stellite tips from equipment removing and assessing condition of stellite tips in line with standard operating procedures |
Context of and specific resources for assessment | Competency is to be assessed in the workplace or realistically simulated workplace Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints Assessment of required knowledge, other than confirmatory questions, will usually be conducted in an off-site context Assessment is to follow relevant regulatory or Australian Standards requirements The following resources should be made available: workplace location or simulated workplace materials and equipment relevant to undertaking work applicable to this unit specifications and work instructions |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the FPI11 Training Package Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required knowledge Assessment must be by direct observation of tasks, with questioning on required knowledge and it must also reinforce the integration of employability skills Assessment methods must confirm the ability to access and correctly interpret and apply the required knowledge Assessment may be applied under project-related conditions (real or simulated) and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances Assessment may be in conjunction with assessment of other units of competency The assessment environment should not disadvantage the candidate Assessment practices should take into account any relevant language or cultural issues related to Aboriginality, gender or language backgrounds other than English Where the participant has a disability, reasonable adjustment may be applied during assessment Language and literacy demands of the assessment task should not be higher than those of the work role |
