Welding arms and holders are equipment used in welding processes. These tools are designed to hold, position, and move electrodes, welding wires, or other welding materials during the welding operation.
During welding, the welding electrode or wires are melted and attached to the material to be welded. As they need to be held in the correct position for welding, welding arms and holders facilitate the welding process, ensuring that welding is done accurately and safely.
Welding arms are typically designed to hold electrodes used in the welding process. They often include a trigger mechanism to control the current flow, used to regulate the high current of the electrode during the welding process.
Welding holders, on the other hand, are designed to hold welding wires or other welding materials. These holders may include a lockable clamp system to keep welding wires in the correct position. Moving these holders during welding enables the welding process to be carried out accurately.
Resistance welding arms and holders, producible through cold bending and chip machining, are made from tough copper alloys such as Cupro MAX (CuCrZr), Cupro CNB (CuCoNiBe), and Cupro NSS (CuNi2Si Cr). The choice of composition is based on the requirements of strength and conductivity. The crucial aspect is that the equipment efficiently conducts electricity and remains undamaged during electrode changes.
WHERE ARE WELDING ARMS AND HOLDERS USED?
Welding arms and holders find applications in various industries and welding processes. These include resistance welding robots in the automotive sector, steel mesh welding machines, condenser welding lines, spot and seam welding in panel radiators, chain welding machines, and the production of steel wire cages.
