Spot welding
What angle should the torch be for spot welding?
Quick answer
Square and clamped — the arms must squeeze the sheets flat together. Angle on a spot gun equals a weak, offset nugget.
Why the angle matters
Angle directs the arc force and the shield. Pushing pre-heats the path and gives a wider, flatter bead; dragging focuses heat into the metal for penetration but risks slag trapping on fluxed processes. Pick per process and stay consistent — wandering angles make wandering beads.
