TWB stands for Tailor Welded Blank, and it means that boards in different material
quality and thickness are blanked and laser welded according to form required in
building automobile.
- Lightening of automobile to reduce fuel efficiency
- Reinforcement of internal damage in considerations to safety
- Usability of raw material
It is the latest automobile lightening method with particularity of initial cost decrease
through enhancement.
To improve automobile fuel efficiency and to take measure on preexisting research on alternative material for iron and steel,the iron and steel manufacturers have organized consortium called ULSAB(Ultra Light Steel Auto Body) after 1994. Since research on automobile lightening technology has been performed, TWB and Hydroforming were selected. TWB is the latest method of construction that simultaneously enhances safety and reduces automobile waste gas, main factor for global warming, by enhancing fuel efficiency of automobile.
