Steel Zinc plating surface Weld Screw with Tapping Thread.
Welding screw is also called energy storage screw, electric bolt welding stud, or planting welding nail, etc.
Welding screw is used in a small range, which is only used in the sheet metal industry and the factory producing the case.
Although the welding screws are strong and not easy to loosen, some things need to be paid attention to in the process of use, so that the welding screws can be connected and used. 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°.
Windproof and ventilation. In windy places, be sure to take measures to block the net, and take appropriate ventilation measures indoors.
In order to prevent the appearance of welding pores, the welding parts must be cleaned up if there is rust, oil stains, etc.
