(1) the method of blocking ventilation is adopted on the back side.
(2) the use of soluble paper or the combination of soluble paper and blocking plate for blocking ventilation.
TIG welding with flux cored wire.SS 304 and 316 Steel Grating
(4) using backing wire (self shielded welding wire) for backing TIG welding.
1. the blocking method is used to block the ventilation protection on the back (i.e. solid core wire +TIG).
When the stainless steel pipe is prefabricated, the weld is usually rotated and welds, and the ventilation is very easy. At this time, the plugging plate is usually used to protect the pipe on both sides of the pipe to protect it. (see chart 1), and the outside is blocked by adhesive.Alloy steel ASTM 4140 round bar for selling
When welding, we should adopt the process of early ventilation, lag stop gas, the outer adhesive edge welding edge tear, because the plate is made up of the rubber and white iron, it is not easy to damage. So this welding method can guarantee the inside of the weld full of argon and guarantee its purity, thus effectively guaranteeing the inner metal of the weld seam not to be oxidized.
