​The process of spot welding is generally carried out according to the following steps: workpiece cleaning - joint design - preloading - electrification - power off forging.

For a spot welding machine with excellent quality, its transformer must first be wound with copper enameled wire in the primary, and the secondary is an integrated water-cooled structure poured with c

​Spot welding machines can be classified into DC and AC according to the current. Many people don't know the distinction between DC spot welders and AC spot welders.

​Spot welding machine, also known as resistance welding machine, is a welding equipment that uses the own resistance of the workpiece to be welded to generate high temperature locally through a large

High production efficiency. Submerged arc welding can use a large current, the penetration ability of the arc is strong, and the penetration depth of the weld is large.

Basic Information Spot welding machine is a highly efficient and versatile industrial equipment used for joining two or more metal parts by applying heat and pressure. This machine is widely used in v

​Welding machines are divided into universal (universal) and special-purpose types according to their uses; according to the number of solder joints welded at the same time, there are single-point, do
