Welding of stainless steel and aluminum alloys?
Thread Content
The inner lining of the cryogenic container is made of aluminum sheet, while the outer shell is made of carbon steel. All connection pipes are made of stainless steel, which raises the issue of connecting stainless steel to aluminum – through welding, flange connections, etc. There must be no trace of leakage allowed, and welding is the best method; is it possible to weld them together? Thank you, friend!

Flange connection is used, which poses a risk of leakage. This is filled with pearlescent sand, and leaks are difficult to handle. 3. Use steel-aluminum transition joints. This one gives the best results and is the most expensive
“3. Use steel-aluminum transition joints. “This one gives the best results and is the most expensive.” Friend, what is a steel-aluminum transition joint? Is it available as a pre-made product? Can that facility produce it? Or are there any samples? Thank you!
You can search on the forum. . Steel-aluminum transition joint. . I’ve said it many times already. Those produced domestically have unstable quality and are not very good. We mainly use Asahi Kasei from Japan and T+C from France
French T+C’s stainless steel and aluminum joints are manufactured using the friction welding process, while Japan’s Asahi Kasei employs the explosive welding process. In terms of price, T+C is the most expensive option; however, its steel-aluminum joints have a longer end face length, which makes it less likely for overheating to occur during welding, thus reducing the welding difficulty compared to Asahi Kasei’s products.
