In situ investigation of chemical composition during TIG welding in duplex stainless steels using Laser-Induced Breakdown Spectroscopy (LIBS)

open access: yesForces in Mechanics, 2022
Many applications in industry require a material-to-material joining process of Duplex Stainless Steels (DSS). Therefore, it is essential to investigate the material's properties during a welding process to control the weld quality.

Influence of nonmetallic inclusions on the resistance of metal weld to brittle fractures [PDF]

open access: yesНанотехнологии в строительстве, 2018
According to statistics, up to 80% of all fixed metal structure accidents are associated with welded joints. However, most of the emergency destructions, usually caused by non-metallic inclusions in the weld metal, are fragile. The probability of brittle

The effect of X80 steel microstructure on CO inhibition of hydrogen embrittlement

open access: yesYou-qi chuyun, 2022
Carbonic oxide(CO) can effectively reduce the risk of hydrogen embrittlement(HE) of hydrogen pipelines by inhibiting the adsorption of hydrogen molecules on the inner wall, which provides a potential solution to ensure the safe hydrogen transportation by

Thermal welding of polymeric biomaterials: Development of a novel device for temperature controlled local application

open access: yesCurrent Directions in Biomedical Engineering, 2021
We present a thermal processing device, equipped for local heating and welding of biomaterials, e.g. electrospun nonwovens or polymer films. Depending on the application and choice of materials, we aim to determine appropriate processing parameters for ...
