   • Select appropriate solder and flux according to the component materials
   • Select appropriate heating methods
   • Apply and control solder
   • Evaluate each finished join
   • Clean, trim, shape and finish components to produce a smooth surface free of sharp edges and irregularities
3. Weld components
   • Identify and position component materials accurately to comply with the design, and in a manner that enables the optimum join to be made
   • Select appropriate welding techniques and equipment
   • Weld components
   • Evaluate each finished weld
   • Clean, trim, shape and finish components to produce a smooth surface free of sharp edges and irregularities

Performance Evidence
