Providing Lighter and Stronger Car Bodies
The structure for constructing rolling stock must be light and strong. In the unlikely event of a collision involving rolling stock, energy must be absorbed to mitigate the impact suffered by the crew and passengers.
Technology for car body structure
Aluminum and stainless steel are used the most in car body structures, each one used where its characteristics are the most suitable.
For instance, KHI has established a technology for producing stainless structures with laser welding instead of resistance spot welding, which leaves visible indentations on the outer panels of car bodies.

Crash analysis technology
KHI's original "efSET" innovative high-speed rolling stock achieves excellent crashworthiness and satisfies safety standards in overseas markets with its crash analysis technology, which optimizes the balance between the absorption of collision energy in the front and the collision energy absorption by intermediate vehicles.
