Porosity of welds

Acid electrode on steel

with high sulphur content.

Electrode oscillates too

much.

Workpieces are too far

apart.

Workpiece being welded is

cold.

Use basic electrode.

Move edges to be welded

closer together. Move slowly at

the beginning.

Cracks in weld

Material being welded is

dirty (e.g.oil, paint, rust,

oxides).

Not enough current.

Clean workpiece before

welding is an essential method

of achieving neat
