Use mechanical methods of joining jewellery or silverware
Overview
This standard covers the skills to produce jewellery or silverware, using a range of mechanical joining techniques such as pegs and cheniers, riveting, screw threads, and hinges. You will use range of materials to be mechanically joined both precious and non-precious, and metallic and non-metallic.
You will be required to work to instructions, use a range of equipment, and a variety of joining techniques.
During, and on completion of, the production operations, you will be expected to check the quality and accuracy of your work, against given tolerances and the specification which may include timescales. You will need to be able to recognise any defects, to determine the appropriate action to rectify them, and to ensure that the finished work meets the required specification.
Performance criteria
You must be able to:
- join different components using a range of mechanical methods in line with industry best practice
- produce a range of products with mechanical joined components in line with industry best practice
- check components are dimensionally accurate, the forming is correct and there are no excessive marks visible in line project needs
- seek support and guidance when problems arise in line with workplace instructions
- check the work for 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
Knowledge and Understanding
You need to know and understand:
- safety precautions to be taken when using mechanical joining methods
