welder performance qualificationsrequirement of welder qualificationin performance qualification the basic attempt is to establish the ability of the
scope of wps and pqra welding procedure specification wps is written qualified welding procedure prepared to provide direction for making production
variables used in wpsdepending on their influence on obtaining a desired weldment the welding variables are then classified and listed some of them
writing of a welding procedure specification wpsa typical working procedure specification is written with all the factors of production in mind both
welding procedure specification wps the purpose of welding procedure specification wps and procedure qualification record pqr is to determine that
metallurgical compatibilitythe two facets of property as above could be made analogous crudely to an athletes wholesome strength which includes both
welding procedure and performance qualificationa total quality assurance scheme embracing all aspects of manufacture would have necessarily made all
intrepretation of defectsintrepretation is an important factor is controlling the quality of the product on economic levels sometimes for want of
structural notchesin t he case of solid solution strengthened alloys and age hardenabled steel the variation in heat io during welding may cause
embrittlementfor use at high strength coupled with good notch toughness all weld structure must be tempered low carbon martensite carbon and
arc strikesrepresent any localised heat affected zone caused by an arc arc strike tends to produce hardening particularly in high carbon steels and
gas porosityporosity is the presence of gas pockets or voids caused by the entrapment of gas evolved during weld metal solidification this porosity
cracks cracks are the linear ruptures of the metal under stress sometimes they appear large and frequently they are narrow separations the major
geometric defects undercutundercut represents a depression into the base metal adjacent to the toe of the weld and if it forms a notch it is a
foreign inclusions slag inclusionsthis is formed due to entrapment of oxides and non metallic solid material in the weld deposit or between the
