Welding flux is a key factor affecting the quality of welding. Therefore, everyone must keep their eyes open when selecting the flux, so how to choose a good quality flux? Here are some elements that Xiaobian helped you organize:

        First, choose good quality. The sintered flux must first learn to smell. If it smells isopropanol, it is good. Although it may be a mixed solvent, the price of the flux added isopropanol will be higher;

        Second, looking at the welding samples is also the main method of selection. Check the difference between the sample and the flux after the welding is completed, such as the specific gravity and acidity value to check the difference;

        Third, select the flux produced by large manufacturers. At present, there are many manufacturers of sintered fluxes, and the quality of the products produced is also uneven. In order to avoid the problem of inferior charging, we must choose products from large manufacturers.
