BUSINESS
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.
- 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
- Manpower supply and
Demand problem - Production
Delay - Industrial Accident
Rate Increase - Delayed
Delivery - Quality
Deterioration
Crisis status of the shipbuilding and welding industries
- 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.
Overcoming the crisis in the shipbuilding and welding industries
- ㆍApply advanced automotive welding technology.
- ㆍPromote the development of an outline for improving welding productivity.
- ㆍEarly establishment of technological innovation infrastructure.
