2. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds
Abstract : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. READ MORE

3. Welding of Heavy Structures Subjected to Fatigue
Abstract : Welding is a key process for heavy steel structures, but it is also a weak link of the structure since fatigue fractures in welds are a common cause for failures. This thesis proposes several changes in order to improve the fatigue properties in a cost effective way. READ MORE

4. Experimental Study on Cold Lap Formation in Tandem Gas Metal Arc Welding
Abstract : 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. READ MORE

5. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects
Abstract : 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).
