Join jewellery or silverware components by soldering
Overview
This standard covers the skills to produce jewellery or silverware using soldering as a joining technique.
You will work to instructions and follow design using a range of hand tools, metals and joining techniques.
During and on completion of the soldering, you will be expected to check the quality of your work by comparing it against the tolerances to be achieved, accuracy to the design instructions and that the soldering work meets the required standard without defects. You will need to report any problems and seek guidance on the actions to rectify them.
Performance criteria
You must be able to:
- produce jewellery or silverware *components using a range of *soldering techniques for different projects in line with industry best practice
- join jewellery or silverware using a range of heating equipment for different projects in line with industry best practice
- produce jewellery or silverware using a variety of joined components in line with industry best practice
- produce jewellery or silverware joining two different metals in line with industry best practice
- clean the completed work visually examining for any faults whilst doing so in line with workplace instructions
- seek support and guidance when problems arise in line with workplace instructions
- check the work for tolerances and defects in line with project needs
- take action to rectify any defects detected in line with workplace instructions
- complete the work to the given specification in line with workplace instructions
- manage waste materials safely and economically in line with workplace instructions
