Problems solved by technology

[0003] The purpose of the present invention is to provide a one-time capacitive energy storage projection welding process between the metal spout and the pot body. This process solves the shortcomings of the original welding process that the welding effect is not good and requires repair welding, and the entire welding process can be done at one time. The spout is welded well, and there is no indentation on the welding surface

Embodiment Construction

[0020] Below we further elaborate the present invention in conjunction with accompanying drawing,

[0021] Such as figure 1 , figure 2 Shown is the stainless steel pot body and spout that need to be welded, of which figure 1 The welding seam between the spout and the body of the middle spout is long, 240MM, and the thickness of the plate is 0.6mm. For this reason, we choose a capacitor energy storage welding machine with a capacity of 35000J. For the structural diagram of the welding machine, see image 3 , Figure 4 . In order to achieve the ideal welding effect, we strictly follow this welding process:

[0022] 1. We pre-bump the welded surface of the optional stainless steel pot body as a whole, see figure 1 shown;

[0023] 2. According to the curved surface shape of the embossed pot body and spout, process the upper and lower electrode heads that completely match the surface of the pot body and spout to be welded; ensure that the upper and lower electrode heads are...

Abstract

The invention relates to a welding technology of mental pot spout and pot body in the field of welding. It is characterized in that it first integer punches the stainless steel welding side and processes the upper and lower electrode rod which is totally anatomists with the pot body, pot spout welding side by the punched pot body, pot spout curved shape.

Description

【Technical field】 [0001] The invention belongs to the field of welding, in particular to a welding process for a stainless steel spout and a kettle body. 【Background technique】 [0002] When the hardware industry produces metal pot products, the connection between the pot body and the spout generally adopts AC continuous spot welding or seam welding. The products produced by these two welding methods have the following disadvantages: A. The sealing is not good, there are 30 % of the workpiece needs continuous repair welding; B, welding time is long, and the spot welding positioning of the kettle body and the spout is also required before welding. C. After welding, the metal surface will turn black and the surface weld marks will be deep, so the workload of grinding in the subsequent process is large and the efficiency is low. D. Need skilled operators. 【Content of invention】 [0003] The purpose of the present invention is to provide a one-time capacitive energy storage ...
