In the process of using the welding nut, we need to pay attention to some matters so that the welding nut can be used for connection. The strength of the welding nut is high, and it is not easy to loosen. The so-called welding is to turn the two separate parts into a whole. The metal is melted at high temperature and mixed together for cooling. The alloy will be added in the middle. The mother is slightly large. Therefore, the use of weld nuts is very extensive. Let's follow the Low price Welded Clamp Nut editor to see what problems need to be paid attention to!

1. The protective gas is argon.
2. The length of the tungsten electrode protruding from the gas nozzle.
3. Use a power supply with vertical external characteristics, and use positive polarity (the welding wire is connected to the negative electrode) when DC is used.
4. In order to prevent the occurrence of welding pores, the welding parts must be cleaned up if there is rust, oil pollution, etc.
5. It is generally suitable for the welding of thin plates below 6mm, and has 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. The welding arc length is preferably 2~4mm when welding ordinary steel, and 1~3mm when welding stainless steel. If it is too long, the protection effect is not good.
8. 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 workpiece at the welding place 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. Usually about 10°.
The above is what the editor of Low price Welded Clamp Nut tells: the issues that need to be paid attention to when using welding nuts.
