304 thin-walled stainless steel tube welding method

For 304 thin-walled stainless steel pipes are believed to be familiar with, because of its good performance is widely used in many industries. In the use of water pipes, the use of more connections is welding. In order to ensure the use of water pipe effect, it will require welding in accordance with the relevant provisions to operate. Xiaobian below to tell you about thin-walled stainless steel pipe welding method.


1, the thin-walled stainless steel pipe welding method is the use of left welding method, welding torch uniform forward, keep up and down without beating.

2, the welding wire along the welding and paste the welding port from the pool before the edge of the join, depending on the amount of space and the speed may be.

3, as little as possible plus attendance, so as to avoid the formation of thin-walled stainless steel pipe weld in the weld and concave welding when the weld convex to weld a forming principle.

4, the end of the wire is always in the range of argon protection, so as not to red hot end oxidation. The wire should not be inserted into the bath to disturb the argon stream.

5, the thin-walled stainless steel pipe welding wire diameter selection of 2.0 ~ 2.5mm, welding current between 40 ~ 100A, argon flow 8L / min, torch nozzle aperture 8mm, Nozzle and the workpiece distance of 5 ~ 10mm.

6, lead in advance when the air 3 ~ 5s. Before the arc must first increase the speed of travel, and then arc to eliminate the crater.

The above description is the thin-walled stainless steel pipe welding methods, of course, the type of water pipes are different, the connection will be different, including welding, clamping and so on, no matter what method of connection, are more Convenient, and the effect is also good, so users in the connection when they should also be based on the actual situation to choose the appropriate connection method.
