Welding Thick-Walled Steel Pipe

When welding thick-walled steel pipes, the oil, paint, water, rust, etc. should be removed first. Then, according to the wall thickness, the thicker groove, the thicker groove is opened, the thinner tank is opened, and the thinner (angular grinder) is opened, and then the gap of the product is typically from 1 to 1.5 times the electrode or wire diameter. If the slot is unexpected, it can be appropriately reduced.
There are at least three points of spot welding, and the four points are suitable for work. When welding, half of the welding should be performed, and the starting point should be 1 cm from the bottom point to obtain a good joint from the other side. When the steel pipe wall is thick, it should be layered, at least two layers, can be welded to the second layer, and the second layer can be welded.
