From the appearance point of view, welding wire and welding rod are not the same concepts at all, one is in the state of a line, and the other is in the shape of a metal rod.
Welding rod: Generally, it is a solid metal rod. It is used as an electrode during welding, and it is switched to a welding current to generate an arc with the welding device and provide filling for itself. The coating can protect the welding process and improve its performance of the welding process.
The welding wire is suitable for MIG, MAG, TIG and other welding methods. The welding wire is divided into flux-cored welding wire and solid welding wire. Its function is to fill metal or conduct welding current.
From the aspect of the welding process, the welding wire is easier to realize automatic welding, improve production efficiency, and standardize welding; the welding rod is more dependent on manual operation, and the technical requirements exceed the welding wire. Soldering wire is generally used by electric soldering irons, and welding rods are used by some large welding tools.
The maintenance method was to use the welding wire reel to wind the product and avoid contact with other substances to prevent welding quality problems.
