Robotic Grit-Blast Surface Preparation For Quality, Efficiency and Flexibility is the title of a presentation delivered at the ASM Thermal Spray Society’s technical conference program on Reliability, Durability and Performance Assessment of Thermal Spray Coatings held on October 8-9, 2013 at the GE Global Research Center in Niskayuna, New York. J. C. Carson, Business Development Manager at Guyson Corporation, gave the talk.
In the only presentation devoted entirely to the subject of surface preparation, a critical requirement for thermal spray coaters, Carson illustrated blast system features for control of grit sizing and flow control, grit delivery and stressed the importance of controlling blast nozzle angle, offset and surface speed. The results of lab testing were included to demonstrate the influence of each process parameter on surface roughness and coating adhesion.
The presenter compared manual grit-blasting, surface preparation by multiple-gun automated blast machines and robotic grit-blast equipment in terms of reliability in control of nozzle position and motion and reviewed some of the latest developments in robotic blasting systems.
