What kind of welding machine is used to weld the hot-press welding tool head and the temperature sensitive wire?

The welding machine usually used for hot-pressing welding tool bit and temperature sensitive wire is resistance welding machine.

Resistance welding machine is a kind of equipment which uses the principle of resistance heating to weld. By applying current to the welded joint, the resistance thermal effect is generated, which increases the temperature at the joint, thus achieving the purpose of welding. Resistance welding machine has the advantages of fast heating speed, high welding quality and high welding joint strength, and is widely used in the welding process of hot pressing welding tool head and temperature sensitive line.

In the welding process of hot-pressing welding tool bit and temperature-sensitive wire, it is necessary to put the joint part of tool bit and temperature-sensitive wire between electrodes first, and then apply a certain current and pressure through resistance welding machine. The electric current produces resistance heating effect through the joint, which increases the temperature at the joint, and the applied pressure can ensure the close contact between the joints. When the joint temperature reaches a certain level, the materials of the cutter head and the temperature sensitive wire will melt to form a welded joint. Then, the application of current and pressure is stopped, and the welded joint is cooled and solidified to complete the welding process.

It should be noted that the welding process of hot-pressing welding tool bit and temperature-sensing wire needs to select a suitable resistance welding machine according to specific materials and requirements. Different materials and requirements may require different parameters, such as current, pressure and welding time. Therefore, before welding, we must fully understand and analyze the materials and requirements to ensure the selection of appropriate resistance welding machine and the correct setting of welding parameters, so as to obtain ideal welding effect.
