the welding speed was fixed as 60 cm/min
and the change in depth of penetration was drawn with
increasing welding current for 22, 24 and 26 V. The biggest
penetration value was obtained in 115 A and 26 V,
while the smallest one in 95 A and 22 V. The change is
similar to the conditions observed in 40 cm/min welding
speed, the depth of penetration increases with increasing
welding current, especially in between 95 and 105 A.
