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

Aluminium Assisted Nickel Alloying in Submerged Arc Welding of Carbon Steel: Application of Unconstrained Metal Powders

open access: yesApplied Sciences, 2022
Nickel alloying of carbon steel is used to enhance steel strength and toughness. Nickel alloying of the weld metal via solid weld wire presents several difficulties as highlighted previously, such as work hardening of the solid weld wire in manufacturing

Reactions at the molten flux-weld pool interface in submerged arc welding

open access: yesHigh Temperature Materials and Processes, 2021
In submerged arc welding (SAW) of chromium (Cr) containing steels, Cr is usually added to the weld metal from the weld wire, and not from the welding flux.

Effect of Filler Wire Feed Rate on the Formation of Porosity in Laser Welded Joints of Magnesium Alloy AZ31B–H24

open access: yesMetals, 2023
In this work, the effect of a filler wire feed rate was studied with special attention to the proportion of porosity volume in the weld metal, microstructure, and mechanical properties. Butt laser weld joints were created using the Nd:YAG laser.

Application of Unconstrained Cobalt and Aluminium Metal Powders in the Alloying of Carbon Steel in Submerged Arc Welding: Thermodynamic Analysis of Gas Reactions

open access: yesApplied Sciences, 2022
The application of cobalt and aluminium powders in unconstrained format, not as metal powder in tubular wire nor as pre-alloyed powder, is used in this work to simplify weld metal alloying. The objective of this study is to demonstrate the application of
