About

Heqing Tang is a researcher specializing in advanced welding and additive manufacturing processes, with a particular focus on gas metal arc welding (GMAW) and wire and arc additive manufacturing (WAAM). His work has made meaningful contributions to understanding how process parameters influence weld quality and manufactured component integrity. Tang's research into double-pulsed GMAW has shed light on the characteristics of weld bead ripples as diagnostic indicators of process quality, offering practical insights for improving welding consistency. His investigations into torch inclination during pulsed-GMAW have clarified how operational geometry affects bead formation, providing valuable guidance for robotic welding applications. Notably, Tang's work on robot-assisted WAAM of 316L stainless steel examines how duty ratio and current mode influence heat input and structural outcomes across multi-layer fabrication — addressing a critical challenge in scaling additive manufacturing for industrial use. With approximately 34 citations across his most recognized publications, Tang's research bridges fundamental process science with practical engineering applications, contributing to the growing body of knowledge that supports the automation and optimization of modern arc-based manufacturing technologies.
