Web8 Apr 2024 · 5. End the weld correctly. Aluminum expands more with heat than most other metals. This means that if you end a weld abruptly, you’ll get a shrink crater. Even more problematic: if you look closely at the crater you will probably see cracks. Tiny cracks tend to grow on heavily stressed parts, which can cause the weld to fail in extreme ... WebWelding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).. In addition to melting the base metal, a filler material …
