In the process of using the welding nut, we need to pay attention to some matters, so that the welding nut can be connected and used. Welding nuts are strong and not easy to loosen. The so-called welding is to make two separate parts into a whole, melt the metal at a high temperature and mix them together and cool down. Alloys are added in the middle. The internal force is the effect of molecular force, which is better than normal. The maternal body is slightly large. Therefore, the use of weld nuts is very extensive. Hex Nut Factory introduces the precautions for using welding nuts:

1. The shielding gas is argon.

2. The length of the tungsten electrode protruding from the gas nozzle.

3. The power supply with vertical external characteristics is adopted, and the positive polarity is adopted for direct current (the welding wire is connected to the negative electrode).

4. In order to prevent the appearance of welding pores, the welding parts must be cleaned up if there is rust, oil stains, etc.

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

6. Windproof and ventilation. In windy places, be sure to take measures to block the net, and take appropriate ventilation measures indoors.

7. For welding arc length, 2~4mm is better when welding ordinary steel, and 1~3mm is better when welding stainless steel. If it is too long, the protection effect will not be good.

8. In order to make the argon gas well protect the welding pool and facilitate the welding operation, the centerline of the tungsten electrode and the workpiece at the welding point 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°.

Through the above introduction, China 2H Hex Nut Factory hopes that you can simply refer to the content of this article in future use.
