Estimated values for the parameters for the Drawn Arc Procedure
1
:
• I[A]  80 x  [mm]
• t[ms]  20 x  mm]
The weld rates assume an additional 0.08 sec power on time beyond the weld time during stud plunge. Stud loading and unloading time
are not taken into consideration which may restrict actual stud weld rate.
1. This estimated values are taken from the standard DIN EN ISO 14555: ʺArc welding of metallic materialsʺ (2006). The estimated
values must be adjusted to the concrete conditions (cable length, surface condition and welding position).
