Pay Attention To These Matters When Welding Stainless Steel Flanges
Jun 14, 2022
Stainless steel flanges are used for oil, water, gas pipelines, or most of a certain pressure. So, what is stainless steel flange welding technology? Stainless steel bellows flanges and pipes are welded clean. If there are cracks and leaks in the weld, the original weld scar should be cleaned up. Straight pipe flange polished, metallic luster. Straight pipe bellows are too thin to be ground. After grinding, use a hand emery cloth to polish the wire.
The welding installation gap of stainless steel flange is 0. Due to the machining error, sometimes there is an excessive gap, and the welding melt is easy to burn through. The treatment method can be to stack the straight pipe flange on the local surfacing layer, and process it to a gap of 0-0.05mm or manually. sanded. Otherwise, the outer diameter of the straight flanged pipe should be smaller or ground flat until it is suitable to stop.
The welding arc of the stainless steel flange is carried out on the flanged pipe. The arc should refer to a thick tube, heating the bellows with an arc flame, plugging the edge of the bellows with welding wire, and melting the bellows with molten stainless steel wire.
When welding, the rods are transported in thick tubes. Welding or spot welding should be chosen to be shorter. Stainless steel flange welding takes time to observe the molten state of the bellows. Typically, one to three molten pools are melted at a time. Not suitable for continuous welding, especially when the gap is large, it is easy to burn through.
