Circulating water cooling liner device for welding and application method of liner device

Abstract

The invention discloses a circulating water cooling liner device for welding. The liner device comprises a liner device body an a circulating water cooling device. The grooves of two to-be-welded plates are oppositely fixed on the upper side of the liner device body. The circulating water cooling device is connected with the liner device. A recessed longitudinal arc-shaped forming groove is formed in each of the four sides of a copper liner which is longitudinally positioned through a retaining plate. A water pump water outlet pipe is connected with a cooling water circulating hole of the copper pad and is connected with a water return pipe of a water storage tank through a water return hose. The invention further discloses an application method of the circulating water cooling liner device. The method includes: fixing a liner seat; selecting the width W1 of each longitudinal arc-shaped forming groove of the copper liner; tightly pressing the copper liner through the retaining plate; connecting water pipes at two ends of the copper liner; fixing the two to-be-welded plates; starting a water pump to feed water so as to cool the copper liner, and welding the two to-be-welded plates. By the longitudinal arc-shaped forming grooves in the copper liner, utilization rate of the copper liner is increased by three times, welding of plates of different thicknesses can be satisfied, and application cost is lowered.

Description

technical field [0001] The invention relates to a circulating water-cooled liner device for a single-side welding and double-side forming process, and also relates to a method for using the device, which belongs to the technical field of welding technology. Background technique [0002] The single-side welding and double-side forming welding process improves welding efficiency, reduces welding costs, and shortens the welding processing cycle. In the implementation process of single-side welding and double-side forming process, in order to ensure good forming quality of the back of the weld, it is necessary to place a liner with a forming groove on the longitudinal lower side of the groove of the two workpieces to be welded before welding. During welding, the molten liquid metal adheres to the lining on the back of the workpiece and is constrained by the forming groove on the surface of the lining, forming a shaped weld on the back of the workpiece that is similar to the sha...
