Welding rod and welding wire are completely different concepts. The welding rod is composed of a coating and a welding core. The welding core is a solid metal rod, which acts as an electrode during welding to conduct welding current and generate an arc between it and the weldment. And provide filler metal itself. The coating is used for protection during welding, metallurgical treatment, and improvement of welding process performance. Electrodes are mainly used for manual arc welding.
The welding wire is mainly used for welding methods such as MIG/MAG and TIG . (That is , the main welding materials used in submerged arc welding / gas shielded welding, electroslag welding, gas welding, etc.) Welding wire is divided into flux-cored welding wire and solid-cored welding wire. Its function is mainly to fill metal or to conduct welding current at the same time. In addition, sometimes the welding wire is used to guide the welding seam over alloying elements. For the self-shielded flux-cored wire, it also plays a role in protection, deoxidation and denitrification during the welding process.
Welding wire is conducive to automatic welding, improving production automation . Standard welding. Manual arc welding mainly depends on the operation level of the welder, but if it is all done manually, the production efficiency of welding rod is higher than that of welding wire, and the welding performance is better.
