If you're interested in a visual of how different welds interact with the metal, I watched this video on SpaceX's Starship welding that was helpful [1]. Something I try to remember is that most non-organic materials gain their properties from a precise lattice structure. This often doesn't come across when looking straight at the chemistry equations. Welding both disrupts and rebuilds this lattice structure, which is why it requires so much skill to do at volume.
