The Use And Maintenance Of Electrode

The use and maintenance of electrodes mainly include the following aspects:

1. The selection of electrode materials should first use copper alloys recommended by technical standards or data, or the best copper alloys that may be used. Secondly, the properties of electrode copper alloys are often significantly different due to different heat treatment and cold working processes. Therefore, Electrode materials should be selected according to different weldment materials and structures. Third, if you need to purchase electrode materials and process them into electrodes yourself, you should pay special attention to the problem that the performance of the materials will deteriorate after improper processing. The performance parameters of electrode materials should be known in detail from the production unit beforehand.

2. The selection of electrodes should give priority to general-purpose standard electrodes. The shape and size of the electrodes should be determined according to the structure and process requirements of the weldment. For example, standard spot welding electrodes and grips have the most forms. It can meet the needs of most spot welding structures. Due to the complex processing and high manufacturing cost of special electrodes or grips, they are only used in special cases.

3. Electrodes for spot welding should generally be selected in common forms according to the characteristics of the weldments.

4. Before welding, attention should be paid to the correct installation and adjustment between the electrode and the machine. All parts and fasteners between the electrode and the machine should be as firm as possible, with sufficient rigidity, and not easy to bend. For example, during spot welding Adjust the position between the electrode, the grip rod, and the electrode arm so that the axes of the upper and lower electrodes coincide.
