Seam Welding application mainly demand leak proof joints. This leak proof seam welding requires constant current welding quality.
During seam welding the dressed contact area of the wheel goes on increasing continuously due to wheel wear. This increase in area leads to lower current densities. Any abnormalities or low current flown during the process gives weak joints and thus leakages in turn.
FORWEL - Kirti Constant Current Welding Controller is mainly designed for real time purpose. during seam welding the monitor of the controller gives alarm as soon as the current falls below the specific limit due to wears. Such tanks can be kept separately for rework. As rework area is clearly known rechecking efforts are minimized.
