Maintain a constant 2-3mm of distance between the white cone of the flame and the sheet surface
for a proper HEAT INPUT and avoidance of BACKFIRE.
Inspection of weld
Inspect the weld bead after cleaning properly with a wire brush, for a uniform width and height of the bead, uniform
ripples, and proper depth of fusion. (Fig 5)
