1. In order to prevent erosion due to heating, the welding should not be too long. It should be 20% less than the carbon steel electrode. The arc should not be too long. The layers should be cool quickly. The narrow weld bead is suitable.
2. The hardening of the stainless steel pipe fittings is quick after welding, which is easy to crack.
3. Stainless steel pipe fittings, in order to improve corrosion resistance and weldability, add an appropriate amount of invariable elements Ti, Nb, Mo, etc, weldability is better than stainless steel pipe fittings.
4. Stainless steel pipe fittings have delicate corrosion resistance and oxidation resistance and are widely used in chemical, fertilizer, petroleum, and medical machinery manufacturing.
5. Stainless steel pipe fittings have titanium calcium type and low hydrogen type.
6. Stainless steel pipe fittings have certain corrosion resistance (oxidizing acid, organic acid, cavitation ), Heat resistance, and wear resistance.
7. When welding stainless steel pipe, it will be heated repeatedly to precipitate carbide, which reduces the corrosion resistance and mechanical function.
