Kinki Sharyo to introduce advanced laser welding technology

Spot welding has been the conventional technique for stainless-steel carbody shell in order to achieve less distortion that occurs from the welding process. However, there has been the problem of indentations made through the spot welding process, so other welding methods have been sought to replace spot welding. However, the result of repeated research into other techniques has allowed for the development of a laser welding structure technology called KSLabo (Kinki Sharyo LAser welded carBOdy shell) that can be applied to stainless-steel carbody shell. We are pleased to introduce hereby an overview of that technology to you. Note that we have been granted the 36th Japan Welding Engineering Society (JWES) award "Technical Award (main prize)" by developing an applied technology of this technique and enabling its mass production.
