Determining welding and related technical requirements to achieve objectives
Overview
This standard identifies the competences you need to determine welding and related technical requirements, in accordance with approved procedures. You will be required to identify the overall activity for which the technical requirements need to be determined, and to gather all appropriate data in order to fulfil the specified objectives. The technical requirements must relate to significant welding and related processes or activities that consist of multiple operations or stages.
Your responsibilities will require you to comply with organisational policy and procedures for determining and specifying the technical requirements. You will report any problems that you cannot personally resolve, or that are outside your personal authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to gathering, determining and specifying technical requirements for welding and related activities. You will understand the welding and related processes within your area of responsibility, including problem solving principles and procedures, in adequate depth to provide a sound basis for carrying out your activities to the required standard. Additionally, you will understand your organisation's methods of operation in sufficient detail to enable you to make informed decisions.
You will be aware of any health, safety and environmental requirements applicable to your area of responsibility. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
Performance criteria
You must be able to:
- clearly identify and confirm the objectives to be achieved
- gather information and assess the work circumstances and their technical implications
- obtain information on the welding and/or technical activities
- identify technical requirements that could deliver the specified objectives
- select and specify for implementation the most appropriate technical requirements to achieve the objectives
- identify and report those requirements which cannot be achieved
Knowledge and Understanding
You need to know and understand:
- the specific safety precautions to be taken when working in a welding and related environment (such as specific legislation or regulations governing the activities or work area, safe working practices and procedures to be adopted, general workshop and site safety practice, risk assessment procedures and relevant requirements of HASAWA, COSHH and Work Equipment Regulations)
- the personal protective clothing and equipment (PPE) that should be worn (such as eye protection, ear and head protection)
- the hazards associated with working in a welding environment (such as electric arc flashes; fumes and gases; hot metal; grinding and mechanical metal/slag removal), and how they can be minimised
- the welding processes being used, and their technology (such as basic principles of fusion welding, AC and DC power sources, power ranges, manual metal arc (MMA), MIG, MAG or flux cored-wire arc welding, tungsten arc welding (TIG), submerged arc, oxy/fuel gas and plasma welding, electron beam, resistance welding, laser and friction welding and other relevant fusion welding processes)
- materials and their behaviour during welding (such as structure and property of metals; heat treatment requirements; types of steel and cracking phenomena, cast iron, copper, nickel, stainless steel, aluminium and their alloys; joining dissimilar materials)
- construction and design of welded joints (such as design principles of welded construction, joint design, behaviour of welded structures under static and dynamic loading)
- general principles of welding components and structures (such as use of jigs, fixtures and manipulating devices; residual stresses and distortion; types of defect and their avoidance; quality control during manufacture)
- types and features of welded joints in plate, tube and sections (including fillet and butt welds, single and multi-run welds, welding positions, weld quality)
- how to obtain information on welding and related activities, and the types of information that will be available
- how to access and use the appropriate information and documentation systems, and your organisation's regulations, guidelines and procedures
- extracting information required from drawings and welding procedure specifications (such as interpretation of welding symbols; scope, content and application of the welding procedure specification) to include symbols and conventions to appropriate British, European or relevant International standards in relation to work undertaken
- the codes and conventions that are used in the welding specifications
- the factors to be taken into account when determining the welding technical requirements, especially those relating to health and safety and working conditions
- the types of data that should be included in the technical information
- the types of resource that are associated with the different types of welding and related activities
- the importance of maintaining records of the technical requirements; what needs to be recorded, and where records are kept
- who needs to be informed about the welding technical requirements
- the organisational procedures for providing information to different people, and the various ways of presenting this information
- the importance of providing the right information at the right time
- the types of problem that can occur when identifying the welding technical requirements and how to avoid them
- the extent of your own responsibility, and to whom you should report if you have problems that you cannot resolve
