| Welding is a core technology in the industrial
plant business, and exercises a direct impact on the enhancement
of productivity and product quality. It plays a central
role in the heavy industries sector. |
| |
| This essential team focuses on the development of products
with high-added value and new technologies in areas such
as automated welding, explosive welding, explosive cutting,
explosive disassembling of structures, laser application
and surface treatments, as well as the development of new
raw materials. |
| |
| The team also is in charge of all certification and education
activities related to welding, both for Doosan employees
and members of the general public. |
