6. What is P&ID?

7. What is WPS?
A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements
8. What is PQR?
A PQR is a record of a test weld performed and tested (more rigorously) to ensure that the procedure will produce a good weld. A WPS is supported by a Procedure Qualification Record (PQR)
9. What is WPQ?
A Welder Performance Qualification (WPQ) is a test certificate that shows whether a welder possesses the necessary experience and knowledge to perform the specifications of a particular weld procedure
10.Different between Pipe and Tube?
PIPE:It is identified by NB(Nominal Bore) and its thickness is identified by schedule
TUBE:It is identified by OD (Outside Diameter) and its thickness is identified by BWG (Birmingham Wire Gauge)
