RISReconstruction of Three Dimensional Gas Metal Arc Weld Pool Surface From Reflected Laser Pattern
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A system has been developed to measure the threedimensional weld pool surface geometry in the gas metal arc welding (GMAW) process. It utilizes the specular nature of the weld pool surface by projecting a fiveline laser ...
Machine Recognition of Laser Reflection From Gas Metal Arc Weld Pool Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The reflection of projected laser lines may be used to determine the three-dimensional geometry of the reflecting weld pool surface. However, for gas metal arc welding (GMAW), the transfer of ...
Investigation into the Preparation, Carbonation Evolution Mechanism, and Rebound Strength of High-Volume Ultrafine Mineral Admixture Concrete
Publisher: American Society of Civil Engineers
Abstract: AbstractAdmixture ultrarefinement is an effective strategy to address the challenges of low
gelling activity and slow early strength development in high-volume admixture concrete.
To further enhance the low-carbon properties ...
