• 07/26/14 ASME Section-IX 3 WPS & PQRWPS & PQR • The purpose of welding procedure specification (WPS) and procedure qualification records (PQR) is to determine that the weldment proposed for construction is capable of providing the required properties for its intended application. • WPS is intended to provide direction for the welder and lists the variables, both essential and non essential and the acceptable ranges of these variables when using the WPS. • 07/26/14 ASME Section-IX 4 WPS & PQRWPS & PQR • It is presumed that welder or welding operator performing the welding procedure qualification test is skilled workman so that welding procedure qualification test establishes the properties of weldment and not the skill of the welder. • The purpose of performance qualification is to determine if the welder is able to deposit sound metal or the welding operator is able to operate welding equipment properly. • 07/26/14 ASME Section-IX 5 Part QWPart QW Part QW is divided into 4 articles. • Article I -Welding general requirements • Article II-Welding procedure qualifications • Article III-Welding performance qualifications • Article IV-Welding data • 07/26/14 ASME Section-IX 6 Test PositionTest Position Before we proceed let us first understand various test position in groove welds in plates, groove welds in pipes and fillet weld in plates etc. In general, • 1G or 1F is called flat positions • 2G or 2F is called horizontal and circumferential • 3G or 3F is called vertical position • 4G or4F is called overhead position • 07/26/14 ASME Section-IX 7 • 07/26/14 ASME Section-IX 8 Test PositionTest Position • Position 5G is only in welds in pipes.

It is a position when pipe axis is held horizontal and circumferential seam is welded without rotating. In a way it is combination of 1G, 3G & 4G. • Position 6G is also for the pipes when pipe axis is at 45 deg. To horizontal plane and circumferential seam is welded without rotating the pipe.
