Sanitary Valve: You can use 2.5 thick or 3.2 thick ER316L welding wire; X-shaped groove can be used for 6mm thick steel plate. When welding, you should pay attention to the problem of welding deformation. You can use the front and back sides to try to offset the influence of the welding deformation zone. CO2 welding method: If you want to get better results, you can use flux-cored wire (E316LT) for custom welding. The reason for choosing the core is that the spatter is small and the welding protection effect is good, but the price is more expensive. During the operation, pay attention to the operation of clearing the root, and then remove the coating before the next welding.

Manual welding: It can also be processed by manual welding. Choose A207 welding rod for welding. The welding of the electrode also requires a layer cleaning operation. Welding skills for argon arc welding of thin stainless steel plates This depends on your specific requirements, weld flatness, deformation size, no need to grind (cast light on the line), 0.7 is OK, 0.4, 05mm how to get it, hehe. Usually, 0.7 plate welding has a certain deformation, and its size is only, to reduce the deformation, please try the following steps.
The current should be small enough to melt the welding wire, about 30A, different welding machines, according to each welding machine; the welding speed must be fast, the faster the better, the smaller the deformation, the more beautiful the weld, if there is water cooling effect is better; the electric welding machine should also be paid attention to, generally use inverter AC and DC welding machines, the current is relatively stable. This kind of welding machine will be more expensive. It's all tactical issues, just practice!
