Welding point interfaces are used as threaded connections in different types of arms and holders so that their conical parts can be replaced, which leads to increasing the life of the main part and reducing production stops. It is also possible to change the dimensions of the adapter to give the necessary changes to the holders.
The raw materials of connectors are mainly copper chromium zirconium class 2, copper beryllium cobalt, NP200 class 3 and brass.
