Spot welder fuses two pieces of sheet metal to the two points closest to the copper head through an electric current.It can also be used to perform touch welding on sheet metal by means of an electric welder.However, it is generally described in the first case that plug welding is a solid phase welding technology, which USES consumable special plug rod to eliminate the FSW tail hole or defect.It has many advantages, such as large depth and narrow gap welding;Low material cost of plug rod;Environmental protection;Fast welding speed, it only needs 20s to fill 100mm deep hole;And can be welding in bad environment.The welding process is as follows: under certain pressure or tension condition, the plug rod rotates through the drive device, and friction with the interface of the plug hole (the hole to be welded) to form plasticized metal, and hold the pressure for a period of time to complete the welding
