A WPS or Welding Procedure Specification is the written document that contains all the information a welder requires to start a welding process. Position, gas, technique, base material, filler metals… are some of the variables that must be featured. A WPS may seem confusing and difficult to understand for new welders, but it is one of the most relevant documents in the welding field and that is why they are an important part of welding training. How should it be written? The best way to do it is using an example of a real WPS and following these steps:
All the basic information about the welding procedure:
Details of the joint design, including root spacing and backing (if the joint needs it and the backing material). This information should feature a graphic representation of the joint to make it easier for the welder.
Information about the base and filler metals that are going to be used in the welding procedure. You should specify the weld type (fillet or groove) and the thickness range of the base metal.
Pre and post weld heat treatment required, gas used and the positions in which the procedure will be performed. The welding progression should be specified if it is required.
Information about each weld pass, including:
Knowing how to write and understand a WPS is key in welders’ training, that’s why real WPS can be introduced in the Soldamatic Augmented Training welding simulator. This way trainees can learn how to understand a WPS and subsequently practice that same procedure with Augmented Reality.
