Embodiment 1

[0028] Embodiment one, see figure 1 , a YG8 hard alloy workpiece and DC53 cold work die steel workpiece welding method: the first step, remove the oil stain and oxide film at the welding place of the YG8 hard alloy workpiece 1 to be welded, and remove the DC53 cold work die steel workpiece 2 to be welded The oil stain and oxide film at the welding place; in the second step, the welding place of the YG8 hard alloy workpiece to be welded and the welding place of the DC53 cold work die steel workpiece to be welded are butted together with a gap to form a weldment pair. The gap is filled with pure copper; specifically, a connecting hole 3 is opened in a YG8 hard alloy workpiece 1, and a connecting head 4 is formed on a DC53 cold work die steel workpiece. The connection holes are blind holes. An air extraction hole 5 is provided on the bottom wall of the connecting hole. The connector extends vertically. A bell mouth section 6 is arranged at the open end of the connecting hole. ...

Embodiment 2

[0030] Embodiment two, the difference with embodiment one is:

[0031] see figure 2 and image 3, the present embodiment is accomplished by a brazing device, which includes a vacuum chamber, a confluence chamber 7 and a heater for heating the vacuum chamber. The vacuum chamber includes a barrel body 8 and a barrel cover 9 . A sealing ring 10 is provided between the bung and the staving. The sealing ring is fixed on the upper end face of the staving, and the bung rests on the sealing ring. The barrel cover is sealed and connected with the barrel body by pressing the sealing ring to form a pressure difference between the outside and the inside of the vacuum chamber by evacuating the vacuum chamber. The vacuum chamber is provided with a first air outlet 11 and a second air outlet 12 . The confluence chamber cavity is provided with a vacuum port 13 and a pressure gauge (not shown in the figure). The first air outlet communicates with the confluence chamber. The second air ...

Abstract

The invention relates to a welding method for a YG8 hard alloy workpiece and a DC53 cold work die steel workpiece. The welding method comprises the following steps that 1, oil stains and an oxide film at the welding position of the workpiece are removed; 2, the welding parts of the to-be-welded YG8 hard alloy workpiece butt joint with the welding parts of the to-be-welded DC53 cold work die steel workpiece at intervals in a spaced mode so as to form a weldment pair, and gaps are filled with pure copper; 3, the weldment part is heated to a set temperature in a vacuum environment and the set duration is kept to enable the pure copper to be fused, the YG8 hard alloy workpiece and the DC53 cold work die steel workpiece are still kept in a solid state, and the molten pure copper permeates into the YG8 hard alloy workpiece and the DC53 cold work die steel workpiece at the same time; and 4, the weldment pair can be cooled, so that the YG8 hard alloy workpiece and the DC53 cold work die steel workpiece are welded together. The welding method has the advantage of being high in welded rate, and solves the problem that the welded rate is low when the YG8 hard alloy workpiece and the DC53 cold work die steel workpiece are welded by an existing method.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method for welding a YG8 hard alloy workpiece and a DC53 cold-working die steel workpiece. Background technique [0002] The method of welding YG8 cemented carbide workpieces and DC53 cold work die steel workpieces is usually brazing. When the existing brazing method is used to weld the YG8 hard alloy workpiece and the DC53 cold work die steel workpiece, there are defects of low welding rate and low connection strength at the weld. Contents of the invention [0003] The invention provides a welding method of YG8 hard alloy workpiece and DC53 cold work die steel workpiece with high welding rate, which solves the problem of low welding rate when welding YG8 hard alloy workpiece and DC53 cold work die steel workpiece in the existing method The problem. [0004] The above technical problems are solved through the following technical solutions: a welding method of YG8 hard allo...
