Can 2024 Aluminum Be Welded To Aluminum. Although 2024 aluminum can be machined, it is not as easy to work with as 6061. But there are a couple exceptions, 2219 and 2519, which can be readily welded with 2319 or 4043 filler metal.
Laser beam welding can be used with crack sensitive materials, such as the 6000 series of aluminum alloys when combined with an appropriate filler material such as 4032 or 4047 aluminum alloys. It’s important to evaluate which alloy is best.
