There are shown the investigation results on the impact of ultrasonic oscillation transfer to a structure element upon seam geometry during semi-automatic welding in protective gas environment. The effects arising in melt during ultrasound superposition, their impact upon the formation of molten pool, geometrical parameters and structure of seam cross-section are considered.
The article analyzes the requirements for various functional coatings. The integration of ultrasonic technologies into the processes for obtaining functional coatings in order to improve their quality has been viewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
