Tsurusoken conducts advanced research on the welding technology for the same and different materials with laser.

Research and Development on the Advancement of the Laser Welding Technology for the Same and Different Materials

We conduct research and development to improve the laser welding technology by evaluating convection phenomena and cooling processes of molten metal with the laser melting/solidification analysis code, while conducting laser welding experiments on the same and different materials, observing phenomena with a high-speed camera to clarify the welding phenomenon, and performing residual stress* determination with high-intensity synchrotron radiation X-rays (SPring-8).

* residual stress

Residual stress is a remaining presuure generated in materilas after heating/welding process or mecahical process.

Because residual stress has a possibility to cause material failure, it needs to be contaroled and reducerd.
