Friction stir welding (FSW) is now widely used in industrial manufacturing fields to join metal
materials. Although it avoids solidification cracking, the combination of thermal excursion …

The inner tank is the core weldment of the electric water heater (EWH). During service,
leakage often occurs at the welds of the inner tank due to stress concentration. Reducing the …

Preheating is generally required in the welding of ultra-high strength steels (UHSSs) for
avoiding cold cracking. The present work systematically explores the influence of preheating …

The hydrogen diffusion behaviors in welded joints of ultra-high strength steel (UHSS), which
are related to hydrogen-induced cracks (HIC) in welding, are not yet fully understood due to …

Longitudinal bending deformation is the most typical mode of welding deformation in long-
straight welded structures with asymmetric cross-sections. It is very critical for manufacturing …

Buckling distortion as a troublesome engineering issue is easily generated in thin-plate arc-
welded components (generally less than 4 mm in thickness). This study aims to clarify the …

Residual stress strongly influences the safety of welded joints of pipelines in mountainous
areas with large slopes. But there isn't an effective calculation model. This paper bases on …

Considering the effect of heat input of tungsten inert gas (TIG) arc welding for T-joint welding
of thin-walled parts of aluminum alloy 6061-T6, here, the welding characteristics are …

In this research, local mechanical tensioning treatment in the form of in-situ rolling
tensioning (ISRT) was applied during friction stir welding of AA2024-T3 sheets. Two types of …

With the development of society and urbanization, higher requirements have been put
forward for the safety and seismic resistance of building structures. The fatigue strength and …
