Abstract

The invention belongs to the technical field of electric resistance welding, and particularly relates to an end plug clamping head. The end plug clamping head comprises a clamping head body and a fixing ring. The outer wall of the clamping head body is sleeved with the fixing ring. The clamping head body comprises three clamping head units which are integrated into the cylindrical clamping head body. Each clamping head unit comprises a cover plate, a layering sheet and a base body from top to bottom, wherein the cover plate, the layering sheet and the base body are integrally formed and are consistent in outer diameter, the inner diameter of the cover plate is smaller than the inner diameter of the layering sheet, the layering sheet and the base body are consistent in inner diameter, the clamping head unit is provided with a screw penetrating the clamping head unit in the vertical direction, and silica gel is arranged on the top of the screw. When the provided end plug clamping head is used for conducting welding, a welded workpiece cannot deform or discolor, and the metallographic structure of the welded end plug and a cladding pipe cannot change.

Description

technical field [0001] The invention belongs to the technical field of resistance welding, and in particular relates to an end plug chuck. Background technique [0002] Resistance welding is a method in which pressure is applied through the electrodes after the workpieces are combined, and the welding method is performed by using the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area. [0003] In the prior art, electron beam welding is used to weld the end plug and cladding tube together, and electron beam welding is complete fusion welding. Therefore, it has certain influence on the use of end plug and cladding tube. The welding adopts the eddy current formed by low resistance (micro-ohm level) and high current (kiloampere level), so that both the end plug and the cladding tube are welded in a molten state (that is, the critical point of melting, but not melted) and rapidly cooled . [0004] Therefore, it is nec...
