| Abstract |
The electrical and thermal fields during a resistance seam welding process for the production of titanium-clad steel plates were numerically analyzed using a finite volume method. Effect of welding parameters such as welding speed, electric current, heating/cooling period, electrode/plate contact area, water cooling intensity, and thermal conductivity of electrode, on temperatures at the bonding layer and titanium surface were studied. With the increase of the water cooling intensity, welding speed, electrode/plate contact area, and thermal conductivity of electrode, temperatures at the bonding layer and titanium surface decreased, but they increased with increasing the heating/cooling period and electric current. Strong cooling, low welding speed, and the use of high thermal-conductivity electrodes were advantageous in preventing oxidation of titanium surface. |
