Pemamek LLC, a North American subsidiary of Finland-based Pemamek Ltd., has developed an automated semi-narrow groove welding solution with proven success in welding exceptionally thick plates ranging ...

The new narrow groove welding means faster welding, fewer additives and fewer mistakes due to a reduced welding need. "Strength, endurance and lightness of structures are essential in steel ...

Residual stresses arise in welded assemblies as a consequence of non-uniform heating and cooling during the welding cycle. Rapid thermal transients induce localised expansion and contraction, leaving ...

For shaft repairs, LBW-W is generally more applicable than LBW-P. The first reason for this is that LBW-W has a lower probability of forming defects, namely porosity, which may result in rejectable ...
