Description
The course is one of the interesting & specialist topic in welding. The course shed light on the definition of WPS & PQR, which lead to the aim of them and influence of industrial projects. On the other hand, the course offered the different between pWPS, WPS & PQR and why we should go through these expressions. In addition, the course exposed to the welding variables, what do they mean? What are their important in formulating the WPS? Welding variables are classified into three categories; essential, non-essential and supplementary variables so the course explains their definitions and their effect on the establishment of WPS. The course draw main rules to qualify a welding process starting with understand the intended application for which the WPS will be used and develop a draft procedure (Called Preliminarily WPS "pWPS" ( after that make a qualification weld and finally test the qualification weld and write up the WPSThe last step in our course is PQR, what is the aim of PQR, how can it prepare? what are the mechanical tests applied on it and what is the acceptance criteria for each test. In addition, we offered an approved example of WPS for more strong understanding. In this example we show all welding variables which we studied in the course with their ranges and also the PQR with its mechanical tests with acceptance criteria
