1 QETI/007 Fabrication and welding principles Credit Value 7 QCF Level 2 GLH 50 Unit purpose/aims Learner pack This unit enables you to develop the general fabrication and welding knowledge essential to support the carry out of related tasks and in support of further learning. This unit involves the use of tools, equipment or machinery and as such must be delivered in a secure and safe environment; learners must be supervised at all times by competent and qualified staff to ensure their safety. All tools, equipment or machinery must be maintained and presented in a safe and fit state for use. The higher risk activities within this unit require safeguarding at all times. Summary of learning outcomes You will: 7.1 Understand the types and application of fabrication hand and machine tools 7.2 Understand fabrication drawing, basic geometry and the application of weld symbols 7.3 Understand mechanical joining techniques 7.4 Understand thermal joining equipment and techniques Assessment requirements An internally assessed multiple choice question paper that assesses the knowledge requirements of learning outcomes An internally assessed task that assesses the practical requirements of learning outcome 7.2.

2 Learner instructions Internal assessment 7.2 weld symbols WHY are we doing this? To demonstrate an ability to draw weld symbols in accordance with BS EN WHAT do we need? Suitable drawing board and drawing equipment to produce the weld symbol drawings on the task sheet Assessment task sheet HOW do we make a start? Observe health and safety procedures at all times. Add weld symbols to a given drawing On the provided drawing of a location bracket draw the correct weld symbols in the identified locations. Marks are given for the symbols, their location on the line and any additional information required by the individual symbol. Continued on next page Page 2 of 6
