Our tailored blank welding system, which uses mash seam welding equipment and YAG laser welding equipment developed in-house, fuse thick steel plates for sections requiring high strengths with thin steel plates in other areas before auto body component press processing is performed, creating highly rigid yet low weight auto body components. This contributes greatly to reduced auto body weight.
This technology overlaps the edges of steel plates, applying a rotating ring of a disc-shaped electrode on both edges, while energizing the plates under pressure in order to perform welding. This is used in large components such as lower dashboards.
YAG stands for Yttrium Aluminum Garnet.
It is used in precision processing using extremely small spot and stable density laser beams. It is exceptionally well suited to difficult processing work, welding hard and brittle materials, and processing new materials.
YAG laser welding produces little warping, etc., due to heat, making it also optimal for microfabrication.
High-tensile strength materials can offer high strengths with thin plates, so hopes are high for thei r effect iveness in automobi le weight reductions. The higher the tensile strength of a material, the more difficult it is to perform press work on, but we are using simulation technologies to research and develop optimal processing methods and are working toward their practical application.
