Ooooh I think I get what you mean that makes sense! then the weld starts deeper on the added stock and then the area that was ground away is rebuilt by the weld, increasing the surface area of the bond as well!
Exactly :3
Also, if you’re welding material with a larger gap between them, you can do a series of tack welds to give yourself more material to work with without burning through the metal. This works better with MIG welding though.
With stick, it’s bad practice but you can take an electrode, knock off the flux, and use the electrode itself as a filler metal.
If you’re using flat pieces of metal together and are afraid of it burning though, you can use a backing bar to both draw excess heat away and reduce the chance of blowing through the weld by providing structure for the weld pool to sit on. You need to use metal with different properties than what you’re welding though, otherwise you’ll just end up with a 3rd piece of metal attached to your weld piece. I think I remember using either bronze or brass.
Oh don't I know it! Like a dozen of these bars have a half inch or more that is all just the electrode filling empty space cause the bar I cut was too short xD
