Welding Electrode – refers to the manual arc welding material with a special coating that is uniformly coated on the outer layer of a certain length of metal wire with a certain thickness, referred to as “welding electrode” for short.
The electrode is made of welding core and coating.
Welding core: the metal core covered by the coating for the welding rod.
Effect:
- Conduct current and generate welding arc;
- Melt to form the deposit metal in the weld bead
Coating: fine-grained substances with different physical and chemical properties are bonded and evenly coated on the surface of the welding core.
Effect:
- Remove harmful elements and add useful elements to make the weld bead have good mechanical properties.
- Ensure the arc is easy to ignite and burn stably and continuously; while reducing spatter
- Improve the properties of the deposit metal
