Requirements For High-Frequency Welding Finned Heaters In The Process Of Welding
Today we will briefly introduce the welding requirements of finned heaters. In order to improve the welding quality, various protection methods have been developed. For example, gas shielded arc welding uses argon, carbon dioxide and other gases to isolate the atmosphere to protect the arc and molten pool rate during welding. Another example is that when welding steel, iron titanium powder with high affinity for oxygen is added to the electrode coating to deoxidize. It can protect the beneficial elements such as manganese and silicon in the electrode from oxidation and enter the molten pool, and obtain high-quality welds after cooling.
At the same time, because the heating temperature is lower than that of fusion welding and the heating time is shorter, the heat-affected zone is small. Many materials that are difficult to be welded by fusion welding can often be welded by pressure welding to form a high-quality joint with the same strength as the base material.
