table. The repair weld shall extend at least 3/8"
beyond each end of the discontinuities being
repaired.
If any of the studs bend tested fail the test or if
there is continued and frequent evidence of
insufficient stud burn off, production must be
halted and appropriate supervisory personnel
notified. The welding variables should be
checked, the necessary adjustments made and the
process and operator qualification procedures
repeated with satisfactory results before welding
continues.
2.8 Closing Comments
Over one hundred million studs of all types are
welded throughout the world each year. Stud
welding is a long recognized and practiced
welding method.
If the method is employed properly using suitable
equipment and qualified settings with trained
operating personnel, approved studs and base
plate materials and appropriate quality assurance
and inspection procedures, it is reasonable to
expect that 100% of all welds made will develop
full strength and full quality.
