What welding method should be used for aircraft shell?

Welding is that all kinds of metals are heated at high temperature, disrupting the arrangement of metal atoms and rearranging them. However, some alloys have memory, and once heated again, they are easy to return to their original arrangement and deform, so rivets can overcome this. This can resist high temperature and impact, and produce many beneficial effects, such as welding stress parts and riveting skin.
