Looks like hiding fingerprints. Take TIG, and melt the bead.
Once upon a time, I messed 200lbs of ss. Was making a lid for street cleaner tank, the parts were not bent perfectly and when Tigged, one surface plane was little bit shifted inwards, no big deal, but one mate suggested to use spoolgunlike mig gun, it was strange looking thing, as I remeber for placing cool weld beads(it didnt spatter), and place beads over the dent, I placed AND heat metal around began to bend in. In the end I`ve got a dumpling, many runs outside, and fat ss pocket inside. They discarded it. I was a practicant then. I respect thin metal.
