" In the vast majority of , it is a very poor and possibly even dangerous practice to weld 7075 or 2024\. The problem is that these two and similar alloys are extremely prone to microcracking, which is not always easily detectable and can lead to catastrophic failure while in service. For this reason, you will never find a recommended filler metal for welding 7075 or 2024 in any manufacturer’s literature." [](
