Description

Technical Field

[0001] The utility model relates to the technical field of resistance welding, in particular to a resistance welding electrode with adjustable heat distribution. Background Technique

[0002] Methods for resistance welding studs to metal sheets are well known in the prior art. An electrode is used herein, which provides a cavity and an inlet in the form of an opening for the stud. Here, a typical stud has a head and a shank. The head is used to support on the metal sheet. The head is welded to the metal sheet. The shank can be smoothly formed or have external or internal threads. Resistance welding has been basically proven especially in the automotive industry, but also in other industrial branches. However, resistance welding may cause residues of the melted material during the welding process to contaminate the electrode. Therefore, the electrode needs to be cleaned frequently. If this does not happen (i.e., the electrode is not cleaned frequently), then the performance of the electrode will gradually decline, which results in a significant quality decline in the welding connection.

[0003] In the existing resistance welding electrodes, when the device welds the metal sheet, the metal sheet is prone to position deviation on the placement table, resulting in the accumulation of solder joints at the solder joint of the metal sheet when the device welds the metal sheet, making the outer wall of the welded metal sheet unaesthetic. Moreover, when the device is working, the welding head cannot be adjusted, thereby causing uneven thickness at the welding part of the device. For this reason, a resistance welding electrode with adjustable heat distribution is proposed. Content of the Utility Model
