Is laser welding a good method for welding thin-walled materials that can withstand low temperatures of -196°C?
Thread Content
I have some thin-walled stainless steel pipes here, with a wall thickness of 0.15 mm. The tube must be able to withstand low temperatures of -196°C (liquid nitrogen). I would like to know about the low-temperature performance of laser-welded joints – is there a possibility of leakage at the weld seam?
What temperature tolerance is required? It’s a matter of the material. . It’s not a problem with the welding method
The performance after welding must be able to withstand the temperature of liquid nitrogen, as liquid nitrogen flows inside the tube. Due to the thin walls, many welding methods can easily puncture the tube. The energy of laser welding is relatively stable; it’s just not clear whether the welding properties of laser welding can withstand such low temperatures.
