Business Overview

Automatic welding equipment

We have established the basic concept and data for welding automation,
and are developing related technologies as it is highly likely to
manufacture and commercialize welding automation equipment.

Business
  • It is possible to more effectively improve existing robot welding in the BIG3 heavy industries, chemical plant, and shipbuilding and marine specialized fields.
  • It is suitable for the rapidly changing market environment needs (fourth industry, smart factory, shipyard manpower supply and demand problems).
  • Currently, we are developing an automatic steel pipe welding system with an automatic tracking device for welding fusion points in the improvement part for digitalization of feasible ship fittings with a clear recognition of the manpower problem in shipyards, including the Ulsan region.

We have established a welding automation technology coaching program to secure the soundness of welding quality by welding engineering with a difference compared to other companies since the development has now been completed and commercialization can be realized.

Why do they need an automated welding facility system?

A vicious cycle occurred due to manpower procurement problems against the increasing order volume of BIG 3 shipyards

Vicious circle
  • Manpower supply and
    Demand problem
  • Production
    Delay
  • Industrial Accident
    Rate Increase
  • Delayed
    Delivery
  • Quality
    Deterioration

Crisis status of the shipbuilding and welding industries

Decreased production competitiveness of shipyards: Since 2010, the domestic shipbuilding industry has seen a sharp drop in order intake due to lower cost competitiveness and intensifying competition to catch up with latecomers. Due to the deterioration in management, professional manpower restructuring and insufficient investment in new technologies led to a decline in production competitiveness.

- Primary vendors of shipbuilding equipment are in a situation where it is difficult to prepare for the long term on their own due to the burden of technology development investment and lack of research manpower.

(Ecosystem Collapse Crisis) The internal ecosystem is in danger of collapsing due to deepening polarization between large shipbuilders, small and medium sized shipbuilders, shipbuilding equipment companies and production subcontractors.

Overcoming the crisis in the shipbuilding and welding industries

Clearly recognize the problem of shipbuilding manpower and realize sales by implementing products that can turn “crisis” into new “opportunities” through prototype development.
  • ㆍApply advanced automotive welding technology.
  • ㆍPromote the development of an outline for improving welding productivity.
  • ㆍEarly establishment of technological innovation infrastructure.
