1. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects
Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).

3. Experimental Study on Cold Lap Formation in Tandem Gas Metal Arc Welding
Sammanfattning : Tandem gas metal arc welding (GMAW) is a high productivity welding process which is appliedin many industries. However, a type of imperfection, known as cold lap, was revealed thatmostly accompanies the tandem GMAW process. LÄS MER
