Abstract

PURPOSE:To stabilize weld position and weld condition by coalescing a convex part to a heater support and laying and fixing the leg of core wire of the heater in two convex parts. CONSTITUTION:A convex part 10 is pressed and molded to get united into a heater support 9. To this convex part 10, the leg of core wire 6 of the heater is touched, laid in by the load of a welding electrode, and then fixed by welding. The convex part 10 will be 0.5-1.5 times as high as the diameter of the core wire 6, while the laying depth of the diameter of the core wire 6 will be more than one third of the diameter of the core wire 6. In this way, welding position can be easily set and welding is stabilized without causing a weld damage to the core wire.
