Why do welding electrodes need heating?
The moisture in the skin of the drying agent prevents the welding from producing hydrogen pores when the water is heated.
1. prevent welding rod damp2. preheating cores, enhanced electrode weldability3. is also a welding process
Prevent welding rod from wettingPreheat the cores, enhance electrode weldabilityIt's also a welding processThe electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece.The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal.
