Joining a repair section to an existing panel starts with the edge preparation rather than the joining itself. A joggler steps the edge down so the new panel sits flush over the old one instead of standing proud along the joint. A joint that stands proud shows through paint however well it is filled afterwards.
The same tool usually flanges as well, turning a 10mm flange for the overlap, and the tools here work in both steel and aluminium sheet. Material thickness is what limits them, since a tool sized for panel steel will not form heavier gauge. A combined joggler, flanging and punch tool covers all three operations from one body.
Plug welding needs a hole rather than a flange. A 5mm punch tool makes the hole for a MIG or spot weld without drilling, which leaves a cleaner edge and does not leave swarf behind the panel where it will corrode. Punching also leaves the metal round the hole undisturbed, which the weld then keys into.
Taking a factory panel off means splitting its spot welds, and a flat spot weld splitting tool separates them without cutting through the panel behind. Cryocobalt drills stand up to the work where a general drill dulls. Hand riveters at 255mm with four nozzles cover mechanical fixing.

Sealey hold the joggler, punch and splitter range with Sykes covering the drills that go with it.
