How to Use Welding Flux?

Welding flux, or soldering flux, is an indispensable substance in the welding process. Its main function is to reduce the interfacial tension between the base material and the solder, thereby promoting the smooth progress of welding. The following is another way to describe the use of welding flux and its main steps:

Preliminary preparation: We first apply an appropriate amount of welding flux to the area to be welded. Then, use tools such as electric soldering irons to preheat the area. This step is to enable the welding flux to play its role more effectively and ensure that the solder can be evenly distributed in the subsequent steps.

Add solder: After the welding part has been fully preheated, we will then apply solder evenly to the welding point. Then, the parts to be welded are closely contacted and fixed with the welding point. This step is crucial because it determines whether the solder can completely fill the welding part to form a stable connection.

Finishing cleaning: When the solder in the welding part is completely solidified, we need to do the final cleaning. This includes removing residual welding flux and solder residue. The purpose of this step is to keep the welding part clean and prevent any residue from potentially affecting the welding quality.
