The metal core covered by the coating in the electrode is called the welding core. The core is generally a steel wire with a certain length and diameter. During welding, the welding core has two functions: one is to conduct the welding current and generate an arc to convert electrical energy into heat energy; the other is to melt the welding core itself as a filler metal and fuse with the liquid base metal to form a weld. When the electrode is welded, the core metal accounts for a part of the...
