This review describes several key laser-arc hybrid modes in LAHW and the fundamental concepts and characteristics of droplet transfer behavior. It focuses on analyzing the key factors affecting droplet transfer from a multi-physics coupling perspective, including force balance, process parameters, auxiliary physical fields, and material properties. Finally, in response to the shortcomings of existing models, it proposes three major directions for future research to provide theoretical support for the industrial application of this technology and to promote its wide application and development. laser-arc hybrid welding droplet transfer behavior force balance process parameters auxiliary physical field material properties Full Text Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
