How much chromium is in stainless steel?
Unlike using traditional steel, stainless steel resist corrosion and creates a healthier weld. This is accomplished by adding anywhere from 10% to 30% of chromium, as well as other elements to the steel. Often this can include adding iron or even nickel alloys. The combination with these other elements and alloys greatly reduces corrosion.
Why is it important to pay attention to the grade of aluminum?
If the proper filler material is not used during the welding operation and the right technique is not employed, cracking and a compromise well are quite common as a result.
Why doesn't aluminum work?
Another reason why this doesn’t really work is that the thermal expansion of aluminum vs steel is hugely different. Aluminum will grow about twice as much as steel as it heats up. That means that as the metal cools off, the welded area is likely to crack under the strain.
How hot does aluminum melt?
Aluminum melts around 1200 F, and steel melts around 2700 F. That usually means that the aluminum will completely melt away before the steel even starts to glow. Even if you can get the metal to pool together, it won’t fuse. You’ll just get globs of steel that are very lightly held on by messy, garbage aluminum.
