Sensing the gas metal arc welding process
Control of gas metal arc welding (GMAW) requires real-time sensing of the process. Three sensing techniques for GMAW are being developed at the Idaho National Engineering Laboratory (INEL). These are (1) noncontacting ultrasonic sensing using a laser/EMAT (electromagnetic acoustic transducer) to detect defects in the solidified weld on a pass-by-pass basis, (2) integrated optical sensing using a CCD camera and a laser stripe to obtain cooling rate and weld bead geometry information, and (3) monitoring fluctuations in digitized welding voltage data to detect the mode of metal droplet transfer and assure that the desired mass input is achieved
Recent development and research at the University of Sheffield blast lab in Buxton, UK
The Blast and Impact Dynamics Lab in Buxton, UK has recently undergone a significant refurbishment due to investment by the University of Sheffield and funding from the Engineering & Physical Sciences Research Council (EPSRC) through a Strategic Equipment Grant. This has complimented development in measurement
techniques funded through standard EPSRC grants and commercial blast testing undertaken by Blastech Ltd. a spin out company of the University of Sheffield
