Welding Hexagon Socket Head Bolt is not easy to loosen, but some things need to be paid attention to in the process of use to facilitate the use of welded nuts. The so-called welding is to make two separate parts into a whole, melt the metal at high temperature and mix them together to cool down, the center will be added to the alloy, the internal is the role of molecular force, which is slightly larger than the usual matrix. Therefore, the application of weld nuts is very extensive.

     1. Use a power supply with straight and external characteristics, and use positive polarity when DC (welding wire is connected to the negative electrode).

  2. It is usually suitable for welding thin plates below 6mm. It has the characteristics of beautiful weld shape and small welding deformation.
  3. The maintenance gas is argon with a purity of 99.99%. When the welding current is 50-150A, the argon flow is 8-10L/min, and when the current is 150-250A, the argon flow is 12-15L/min.
4. The outstanding length of the tungsten electrode from the gas nozzle is preferably 4-5mm. It is 2-3mm in places with poor shielding properties such as fillet welding, and 5-6mm in places with deep grooves. The distance from the nozzle to the operation is usually not More than 15mm.
  5. In order to avoid the appearance of welding pores, the welding parts must be cleaned up if there is rust and oil stains.
  6. The length of the welding arc. When welding ordinary steel, 2~4mm is better. When welding stainless steel, 1~3mm is better. If it is too long, the maintenance effect is not good.
7. In order to maintain the welding pool with argon gas and facilitate the welding operation, the center line of the tungsten electrode and the welding workpiece should usually adhere to an angle of 80-85°, and the angle between the filler wire and the surface of the workpiece should be as small as possible. Usually around 10°.
8. In order to maintain the welding pool with argon gas and facilitate the welding operation, the center line of the tungsten electrode and the workpiece at the welding point should usually adhere to an angle of 80-85°, and the angle between the filler wire and the surface of the workpiece should be as small as possible. Usually around 10°.
