To avoid spalling surfacing steel parts should not produce more than two layers. For welding large thicknesses lower layers of deposited electrodes other marks, depending on the composition of the parent metal.

Metal tends to form small cracks do not reduce the operational resistance of the weld parts. Surfaced metal must be thoroughly cleaned from oxides, rust, grease, moisture, paint and other contaminants.
