Problems solved by technology

[0008] 1. During welding, the panel and the tank cannot be positioned accurately. Once the positioning is not accurate, the panel and the tank will not be effectively connected together, cracks will appear during use, and the service life of the stainless steel sink after welding is short
[0009] 2. Due to the high welding temperature during welding, it is necessary to continuously cool the weld seam and the welding head. However, the above-mentioned existing resistance welding machine does not have a cooling system, which causes the welding head to soften due to heat and the weld seam unevenness, unevenness
[0010] 3. Workers need to put a single panel and tank together for welding when welding, and then change to another one for welding after welding. When changing the panel and tank, the welding machine needs to be stopped, which reduces the welding efficiency

Abstract

The invention discloses a special electric welding machine for welding a stainless steel water tank. The special electric welding machine comprises a rack, a welding head connecting rack and a welding head, wherein the welding head is connected to the rack by virtue of the welding head connecting rack; the special electric welding machine further comprises a workbench and at least two locating pieces; the workbench is fixedly arranged on the rack and positioned below the welding head; the workbench is provided with multiple locating holes; the locating pieces are arranged in the locating holes. As actual conditions during stainless steel water tank welding are fully considered, the special electric welding machine is accurate in locating and free from welding deviation.

Description

technical field [0001] The invention relates to an electric welding machine, in particular to an electric welding machine for welding a stainless steel water tank body and a panel. Background technique [0002] In the field of stainless steel water tank production, the commonly used method is to produce the tank body and panel of the stainless steel tank, and then weld the panel and the tank body with a welding machine. The commonly used electric welding machine is a resistance welding machine. The principle of the resistance welding machine is to compress the workpiece to be welded between the two electrodes, and apply current, and use the resistance heating effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to heat it to a molten or plastic state, so that it forms a metal A combined machine. The resistance welding machine is divided into: single-phase AC resistance welding machine, intermediate frequency inverter wel...
