Welding is to make two separate parts into a whole, melt the metal at high temperature and mix it together and cool it down. The alloy will be added in the middle. The internal force is the effect of molecular force, which is slightly larger than the general matrix.

Weld screw Generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful welding seam shape and small welding deformation.

In order to make the argon gas well protect the welding pool and facilitate the welding operation, the center line of the tungsten electrode and the welding workpiece should generally maintain an angle of 80-85°, and the angle between the filler wire and the surface of the workpiece should be as small as possible. It is generally about 10°.
