DIN557 A2-70 Stainless Steel Customized Square Coarse Thread Nut
1.Product Description
Square welding nut is one of the nuts, is used in a wide range of, and although the strength of the welding nut, not easy to loosen, but in
There are also some precautions to be taken in order to weld nut connections.Welding is the process of turning two separate parts into a whole.
Melt the metal with a high temperature after mixing together in the cooling, the middle will add alloy, internal molecular force is the role, than the general matrix slightly larger
1. Generally suitable for the welding of thin plates under 6mm, with the characteristics of beautiful welding seam formation and small welding deformation.Non-standard custom-made
2. The shielding 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 the current is 150-
At 250A, argon flow is 12-15l /min.
The included Angle between filler wire and workpiece surface should be as small as possible, generally about 10°.
