There are several common welding methods for iron fitting
There are several common welding methods for iron fitting:
1. arc welding
Arc welding is the most widely used welding method at present. It includes hand arc welding, submerged arc welding, tungsten arc welding, plasma arc welding, melting pole gas shielded welding and so on.
2. hand arc welding is one of the earliest and most widely used welding methods in various arc welding methods. It is used as electrode and filler metal coated with an external coated electrode, and the arc is burned between the end of the electrode and the surface of the welder.
3. submerged arc welding
The submerged arc welding is the electrode and the filled metal with the continuous wire. In welding, a layer of granular flux is covered on the top of the welding area, the arc is burned under the flux layer, and the end of the wire and the local material are melted to form the weld seam.
4. tungsten arc welding arc welding
This is a kind of arc welding with non melting polar gas protection, which uses the arc between the tungsten pole and the workpiece to melt the metal to form the weld. Tungsten welding process to melt, only play the role of the electrode. At the same time, the nozzle of the torch is sent into argon or helium for protection. Metal can also be added as needed.
5. plasma arc welding
Plasma arc welding is also a kind of non melting polar arc welding. It is the use of the electrode and the workpiece between the compression arc (called forward transfer arc) to achieve welding. The electrodes used are usually tungsten poles. Plasma gas produced by a plasma arc can be used as a mixture of argon, nitrogen, helium or two of them. At the same time, the nozzles are also protected by inert gas. It can be filled with metal in welding and not filled with metal.
