Procedure Qualification Record (PQR) is a document that consists of procedures for creating and testing the sample welds, and the final results as well. PQR is a prior step before Welding Procedure Specification (WPS) document. Simply, a procedure qualification record (PQR) is a supporting document for WPS. A PQR serves as evidence that the given …
Welding Cost Estimation and Calculation is an important step in all the welding processes. It determines the time of completion of fabricating welded structures and components. Welding cost estimation also plays a crucial role in welding shops run by independent welders. The requirement of cost calculation arises due the various factors like labor cost, time …
Welding Symbols are unique guides and instructions in form of graphs, diagrams, and images. They are necessary elements of engineering and welding. The weld symbols are specific in their nature for particular types of welds. Welders employ various types of welds and joints as per the demand of clients and the designated structure of the …

DCEN and DCEP in welding are two important current polarities. Both play a crucial role in all types of welding activities. The polarity means the direction of the current that flows through a circuit. In the DCEN circuit, the current moves from the electrode to the workpiece. And in the DCEP circuit, the flow of …
