What is standard WPS?

A Welding Procedure Specification, or WPS, is a formal written document describing standard welding procedures. Like a recipe for welders, these procedures provide clear direction for your welders to make quality products that are up to code and industry standards. A WPS can go beyond just a great weld.

How many welding positions are there as per ASME Section IX?

The 1998 edition of Section IX has more than 200 variables, many with multiple conditions, for 13 welding processes and special processes.

Why PQR is required?

This initial procedure is used to create a series of welds which are then mechanically tested to ensure they meet all applicable requirements. In short, a PQR serves as evidence that a given WPS can, in fact, be used to produce an acceptable weld.
