An experimental investigation involving gas metal arc welding is carried here to determine
the temperature distribution, longitudinal and transverse residual stresses and distortions in …

This study aims to minimise the residual stresses and distortions in thin butt-welded
aluminium alloy 5052-H32 plates during gas metal arc welding process by using three …

During the assembly of steel structures, unacceptable weld defects may be found. An
economical solution is local thermal gouging of the affected areas and re-welding. Due to …

The sustainable and resource-efficient production of wind energy plants requires the use of
modern high-strength fine-grain structural steels. This applies to both foundation and …

Related to weld quality, level of imperfections is limited which can result in the need of
grinding and repair welding. It results in material removal and additional heat cycles causing …

High-strength steels offer potential for weight optimization due to reduced wall thicknesses
in modern constructions. Additive manufacturing processes such as Wire Arc Additive …

High-strength steels are increasingly applied in modern steel constructions to meet today's
lightweight requirements. Welding of these steels demands a profound knowledge of the …

Significant cost and time savings may be realised if multiple weld repairs are undertaken at
the same location during the long-term maintenance of naval vessels. Consequently, this …

In welding of high-strength steels, eg for foundations and erection structures of wind energy
plants, unacceptable defects can occasionally be found in the weld area, which should be …
