Welding Procedure Development

When you bake a cake you require a recipe to ensure the final product is what you are after. The same must be said when performing all types of welding. A welding procedure must firstly be developed and tested to ensure you obtain a sound weld in accordance with the relevant specification.

When developing a welding procedure, all the variable essentials must be considered. Such things as material, joint preparation, welding consumables, welding wire/electrodes, welding gas, amperage, voltage, travel speeds and gas flows. In some cases other items such as pre-heating and post heating may also become part of the final welding procedure requirements.

Once the Welding Procedure has been developed, a sample simulating the production welding is welded and then subjected to various Non-Destruction and Destructive tests. If all the tests results comply, then this welding procedure can be used to carry out the associated production welding. With special alloys it may require specialized development to achieve a satisfactory welding procedure that will satisfy the welding requirements.
