Linear slag inclusion
NettetLinear indications are mainly cracks, lack of penetration, lack of fusion, and elongated slag inclusions. Rounded Indication: Any indication with a length equal to or less than three times the width. A rounded indication may be circular, elliptical, conical, or … NettetSlag inclusions are nonmetallic particles trapped in the weld metal or at the weld interface. Slag inclusions result from faulty welding technique, improper access to the joint, or both. Sharp notches in joint boundaries or between weld passes promote slag entrapment.
