Abstract

PURPOSE:To form a perfectly-welded part with no insufficient fusion by perheating the front of a welding line of Cu, etc., and then by driving a welding car truck when the heated temperature exceeds a set temperature to control the temperature automatically for gas shield arc welding. CONSTITUTION:Welding-line position B in front of point A where arc 17 is generated is locally preheated by heating torch 4. The temperature of heating part B, measured by detector 3, is compared with the set temperature of setter 1 and heating is carried on until the difference becomes zero. When the difference reaches zero, motor 8 for the run of welding car truck 7 is driven in its progress direction through amplifier 2. In this way, preheating for gas shield arc welding at point A of Cu and Cu alloy high in thermal conductivity or welded material 9 requiring preheating is automatized and its control can also be performed definitely, so that a perfectly-welded part can be realized.
