  • Description: 2H Heavy Hex Nuts Manufacturers introduces what are the precautions for using hexagonal weld nuts? 1. 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). 2. Generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful welding seam shape and small welding deformation. 3. The protective gas is argon with a purity of 99.99%. When the welding current is 50-150A, the argon flow is 8-10L/min, when the current is 150-250A, the argon flow is 12-15L/min. 4. The protruding 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 work is generally not More than 15mm. 5. In order to prevent the appearance of welding pores, the welding parts must be cleaned up if there is rust and oil stains. 6. 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. 7. 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°. 8. Windproof and ventilation. In windy places, be sure to take measures to block the net, and take appropriate ventilation measures indoors.
