When welding with shielding gas, a 10% longer time is normally selected.
When welding alloyed steel, a 10% lower current is normally selected.
The given values apply to weldings in the welding position PA. The welding time shall be
reduced for welding in the welding position PC.
In the case of short cycle stud welding, the welding time is less than 100 ms. It depends not
only on the stud diameter, but also on the available current intensity (I[A] = min. 100 x Ø (mm)).
The welding time should be as short as possible in the case of welding without weld pool
protection.
Welding energy is only selected by welding time.
Further notes on
– welding elements
– prestress at installation (tie load) and torque
– material combinations
see appendix and operating manual of the according welding
gun.
