Repair of outer plate breakup welding
Outer plate being breakup welding is caused by bad welding between welding wire and metal plates. For
the general breakup welding of the welding seam, a new welding can be applied after removing the
welding wire accumulated at the joint. For the breakup welding of spot-welding, you can use a one-side
spot welder to spot-weld nearby the breakup welding points. The new points are 10-15mm away from
the original points. Before spot-welding, you should clean up the greasy dirt and rusty spot at the welding
points and also make sure that the plates are well aligned.
For the breakup welding that occurs at the flanging edges, an intermittent gas welding can be applied at
the edge of the plate to make the plate edge melted after the 2 plates are well aligned. The every seam
length of the intermittent weld is about 30mm, and the interval of welding seam can refer to the former
welding interval.
Another repair method for outer plate breakup welding is plug welding. It is better to apply CO2 gas
protecting welding. Drill a hole of diameter 6mm on the outer plate, and then press and well paste the
2 plates. Fill the hole with welding wire by CO2 gas protecting welding. When welding, the welding wire
moves in circular way directing to the inner plate to have the inner and outer plates merged together.
After welding, polish and trim the surface, and then paint.
