What Are The Precautions When Using Welding Nuts?
Welding nut is a kind of important fastener, but some people may not know much about them. As a professional fastener supplier, Xinchi Fastener Co., Ltd. has rich experience in the fastener industry. We can supply different weld nuts, such as square weld nuts, carbon steel weld top spring nuts, and so on. We are pleased to introduce the relevant knowledge of welding nuts to you.
Welding nut is indeed not easy to loose, but in the process of use, we also need to pay attention to some matters, so as to connect the welding nut to use. The so-called welding is to make two separate parts into a whole, through high-temperature melting metal mixed together and then cooling. In the center, an alloy is added, and inside, the molecular forces are stronger than usual. Therefore, welding nuts are widely used.
Choose a straight external characteristic of the power supply, DC selection of positive polarity (welding wire with the negative electrode).
A welding nut is usually suitable for the welding of thin plates less than 6mm, with beautiful weld forming and small welding deformation characteristics.
The maintenance gas is argon with a purity of 99.99%. When the welding current is 50-150A, the argon flow rate is 8-10L/min, and when the current is 150-250A, the argon flow rate is 12-15L/min.
The contact length of the tungsten electrode from the gas nozzle is 4-5mm, 2-3mm in the place where the shelter is poor, such as fillet welding, and 5-6mm in the place where the groove is deep. The distance from the nozzle to the operation is usually not more than 15mm.
In order to avoid the appearance of welding pores, if the welding part has rust, oil, etc., it must be cleaned up.
When welding ordinary steel, the welding arc length of 2~4mm is the best, and when welding stainless steel, 1~3mm is the best, too long maintenance effect is not good.
In order to maintain the welding pool well with argon and facilitate the welding operation, the Angle between the center line of the tungsten pole and the workpiece at the welding place should usually be 80-85°, and the Angle between the filler wire and the workpiece surface should be as small as possible, usually about 10°.
Windproof and ventilation. Windy local, please adopt the method of the screen. And if it is indoors, it should adopt the proper ventilation method.
