Abstract
PURPOSE: To save processes and produce excellent products at low cost, by punching a guide groove of desired shape in an iron plate, rounding it in a drum form, welding the contact of the adjoining both ends and cap fitting to the tube opening, and hardening and grinding.
CONSTITUTION: An iron plate 1 of a proper thickness and a guide groove 2 of desired shape are punched simultaneously by one punch by a press or the like. By rounding into a drum form, the contact of the adjoining both ends 3, 4 of the iron plate and cap 5 fitting to the tube opening is welded. This welding is carried out by the plasma arc welding which is capable of welding deeply and concentratively in a narrow area of the work. Then, hardening and grinding are performed.
