Updated on: 03/04/2024 This unit introduces learners to the range of manual and automated welding processes, equipment and applications that support the manufacture of many of the products we see within our homes, places of work and the communities we live in. The learner will be able to demonstrate an understanding of the principles of the metallurgy of weld materials and their behaviour during and post welding operations. They will understand the structure of a weld and the metallurgical effects and stresses induced on a range of materials as a result of the weld process. They will also understand the influence of how weld design can support structures under different types of loading.
