Keyhole-induced porosity occurring in deep-penetration laser welding is a large issue in
laser manufacturing large-thickness components. In order to improve understanding of the …

Welding production efficiency is usually optimised if full penetration can be achieved in a
single pass. Techniques such as electron and laser beam welding offer deep high speed …

In this study, AISI 304 and AISI 410 stainless steels were welded together by a fiber laser-
TIG hybrid welding system. Weldability was evaluated through the characterization of the …

Keyhole-induced macro-porosity, which results from the collapse of the keyhole that formed
by the reaction forces of metal vapors, is a major problem limiting laser and laser-arc hybrid …

Laser welding and laser-based powder-bed fusion additive manufacturing in the deep
penetration (keyhole) mode are promising technologies for the synthesis of metal …

Laser and hybrid laserarc welding present significant opportunities for thick sec tion welding
of nickelbased alloys during the construction and repair of nuclear power plant components …

The weldability of AA7075-T651 during keyhole laser and laser–arc hybrid welding was
studied using microstructural and X-ray radiography techniques. The results showed that the …

The mechanical response of laser welds in complex load states can be highly variable,
underlying the need for models that can accurately predict mechanical behavior to ensure …

Laser welding has gained more and more industry acceptance due to narrow heat affected
zone, low distortion levels, possibility of remote processing, and outstanding welding speeds …
