SRI International Partners with Kawada Technologies and Kawada Industries to Introduce Weld-Visualization Technology and Next-Generation, 3D-Welding Helmet
MENLO PARK, California, Sept. 19, 2019 /PRNewswire-AsiaNet/ --

--New 3D-welding helmet will allow for training new welders and enhancing
  productivity of existing welders, by presenting a live high dynamic range
  scene and welding data safely to the welder's eyes

Technologies, Inc. (

) (KTI) and Kawada Industries to develop Xtreme Dynamic Range (XDR) weld 
visualization technology that uses image processing to visualize live weld 
details to the welder safely. XDR has been further applied to a 
next-generation, 3D-welding helmet that uses cameras to completely transform 
the world of welding.

XDR Weld Visualization Technology

For this project, the objective was to enable a larger number of welders and 
improve their welding quality by greatly enhancing visibility of the welding 
scene using ordinary image sensors rather than special high cost image sensors. 
Specifically, the newly developed technique manages shutter speed and the time 
at which images are captured with microsecond resolutions to acquire images to 
perform real-time XDR Fusion. As a result, instead of the limited commercial 
camera dynamic ranges of 60-70 dB, the dynamic range of the visualized scene 
using commercial cameras in the XDR welding helmet, is expanded up to 150 dB 
without the need for special image sensors. 

Next-Generation, 3D-Welding Helmet

The next-generation, 3D-welding helmet equipped with XDR acquires and 
synthesizes images as a stereo camera unit. These images are displayed, with 
minimal delay, inside the helmet on a head-mounted display (HMD) as a stereo 
image. This helmet system runs on wearable hot-swappable batteries and 
therefore can be used indefinitely in environments that have no external power 
source. The helmet also includes display and recording functions of various 
real-time welding status parameters related to welding (temperature, voltage, 
current, etc.). This allows welders to easily collect and check useful 
information to ensure a high-quality weld, which in turn accelerates the 
learning curve. Finally, the welder's eyes are completely protected from arcs 
because the weld is viewed indirectly through the screen in the helmet. 

SRI International, a research center headquartered in Menlo Park, California, 
creates world-changing solutions to make people safer, healthier and more 
productive. Kawada Industries' unique techniques for manufacturing thick steel 
plates have led to much success in the construction and bridge engineering 
industries. With the cooperation of SRI, KTI Kawada Group developed XDR. KTI 
Kawada Group is also working on analyzing data obtained by the helmet to 
perform various tests for improving the quality and reliability of welding.

"Kawada came to SRI with a need to greatly shorten the time required to train 
new welding technicians while continuing to pass down welding knowledge in an 
effective manner to new welders," said Mike Piacentino, Senior Technical 
Director of Vision Systems for SRI International. "The real-time 
weld-visualization technology developed by SRI provides higher dynamic range to 
allow humans and robotic welders to see more than just the welding tip. The 
ability to view real-time welds maintains quality and informs the welder of low 
quality or possibly failing welds, which is a critical advantage over 
conventional welding where precision welds are critical to structural integrity 
and public safety of infrastructure such as construction and bridge 
engineering."

The next-generation, 3D-welding helmet will be improved over the next year and 
will be utilized to teach technical welding skills at Kawada Industries. The 
KTI Kawada group is expected to gain insights that can be applied to support 
new technological and product developments.

"Welding is the most important and difficult skill to transfer from skilled 
welders to novice welders," said Noriyuki Kanehira, Project Leader and 
Director, Kawada Technology Research Center. "Visualization is the key. This 
new technology developed by SRI clearly visualizes the entire area of the 
workspace with appropriate brightness and contrast. Welding visualization 
directly leads to stabilizing welding quality and providing trace-ability."
