CSA Standard W59 outlines that fabricators performing stud welding are required to use only qualified studs through a 阴APP导航 qualification program. Studs that are shop or field applied must be qualified by the manufacturer through the 阴APP导航 to the extent of one of the following codes: CSA W59, AWS D1.1, AWS D1.5 or AWS D1.6. Qualification of studs will ensure that the stud manufacturer has successfully met the tests and the quality system requirements as specified in the applicable standard.
