procedure qualification record (PQR) A record of the welding data and variables used to weld a test coupon and the test results used to qualify the welding procedure.3.82 welder performance qualification (WPQ) A test administered to a welder to demonstrate the welders ability to produce welds meeting prescribed standards.WELDING PROCESSES INSPECTION - Apr 16,2010 mechanically anchored flat bottom tanks welding procedure and welder qualifications#0183;Welding inspection includes much more than just the non-destructive examination of the completed weld.Many other issues are important,such as review of specifications,joint design,cleaning procedures,and welding procedures.Welder qualifications should be performed to better assure the weldment performs properly in service.The Four Different Types of Retaining Walls That Every Has a plate and anchor head which is a threaded nut and allows the steel to be prestressed and locked off.Grou t Provided a medium through which load gets transferred to the soil and also protects the pre-stressing steel from corrosion.Because these tendons are angled,there will be a horizontal and vertical component of the soil reactions.
