In the field of metal welding, cold welding machines are undoubtedly very popular, but do you know the reasons why cold welding machines are popular? Let's find out with Chengdu cold welding machine manufacturer Xiaobian:
1. Reasonable design and free adjustment . Different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.
2. Small heat-affected area. There is no heat input during the instant of stacking, so there is no deformation, undercut and residual stress. No local annealing will occur, and no re-heat treatment is required after repair.
3.Minimum welding repair impact, the welding machine overcomes the phenomenon of ordinary argon arc welding on the periphery of the workpiece during the welding repair process. The machining surface of the workpiece without the rest can also be repaired with confidence.
4.High repair accuracy: the thickness of the overlay welding is from a few microns to a few millimeters, just grinding and polishing.
5.High welding strength: due to sufficient penetration of the material on the surface of the workpiece, strong bonding force is produced. 6.Easy to carry: light weight (28-30 kg), 220V power supply, no working environment requirements.
7.Economy: Immediate repair at the scene, improve production efficiency and save costs.
8.Multi-purpose for one machine: It can perform overlay welding, surface strengthening and other functions. By adjusting the discharge power and discharge frequency, the required thickness and finish of overlay welding and strengthening can be obtained.
9. Hardness of the overlay layer and the variety of supplementary materials: Different electrode rod materials (supplementary materials) can be used to obtain different hardness requirements.
