No welding equipment manufacturer can promise that once a WPQR package is purchased, no further tests are required to comply with EN 1090. The notified body is the ruling authority. If the notified body does not believe the welders are able to consistently produce welds of the desired quality, they will order welding procedure qualifications. This is why ESAB offers very specific groups of WPQRs. Doing so enables you, the fabricator, to benefit from our expertise without having to purchase welding procedure specifications that you will need to qualify on your own.
