A computational fluid dynamic analysis of the effect of weld nozzle geometry changes on shielding gas coverage during gas metal arc welding [PDF]

open access: yes, 2013
Three geometry changes to the inner bore of a welding nozzle and their effects on weld quality during gas metal arc welding (GMAW) were investigated through the use of computational fluid dynamic (CFD) models and experimental trials. It was shown that an

Hybrid welding of steel 4330V

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The article describes the hybrid welding process (Laser-MAG) of 4330V steel. This steel is a high-strength, micro-alloy material with tempered martensite structure. The microstructure of tempered martensite is obtained through the heat treatment process and through the vanadium micro-additive.
