  • Page 29: Functional Principle Of Stud Welding

    – The use of contact welding for rapidly oxidizing materials like aluminum and aluminum alloys is limited, as the arcing period with contact welding is longer than with gap stud welding. KAH 412 LA Order No. BA 94-37-412 Issue 23.10.08...

  • Page 30: Gap Stud Welding

    With high plunging speed of the welding element, the air gap closes after vaporization of the ignition tip faster, thus the arc time becomes shorter. With rapidly oxidizing materials like e.g. aluminum, the arc must only burn a very short time. KAH 412 LA Order No. BA 94-37-412 Issue 23.10.08...

  • Page 31: Drawn-Arc Stud Welding
