Producing socket and flange fillet welded joints in pipe using a manual welding process

​

This standard identifies the competences you need to produce socket and flange fillet welded joints in pipe, using a manual welding process, such as manual metal arc (MMA), MIG, MAG, TIG, flux cored wire, plasma or oxy/fuel gas welding equipment, in accordance with instructions and/or approved welding procedures. You will be required to check that all the workholding equipment and manipulating devices required are available and in a usable condition. You will be expected to check the welding equipment to ensure that all the leads/cables, hoses and wire feed mechanisms are securely connected and free from damage.

In preparing to weld, you will need to set and adjust the welding conditions, in line with the instructions or welding procedure specification. You must operate the equipment safely and correctly, and make any necessary adjustments to settings, in line with your permitted authority, in order to produce the welded joints to the required specification. You will be required to demonstrate your capability to produce the fillet welds to the required quality, and this could be through tests according to relevant standards (for aluminium)

Your responsibilities will require you to comply with organisational policy and procedures for the welding activities undertaken, and to report any problems with the welding equipment or welding activities that you cannot resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, taking personal responsibility for your own actions and for the quality and accuracy of the work that you produce.

Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will provide an understanding of how the particular welding process works. You will know about the equipment, materials and consumables, in adequate depth to provide a sound background for the welding operations to be performed, and for ensuring the work output is produced to the required specification.

You will understand the safety precautions required when working with the welding equipment. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
