Another new technology! Korean shipyard successfully develops hull marking and painting welding robot

On September 21, the final acceptance and demonstration event of the "Hull Marking Welding Automation Equipment Using Collaborative Robots" jointly developed by South Korea's K Shipbuilding and Doosan Robotics was held. This is another successful case of the "2023 Small and Medium-sized Shipbuilding Enterprises Intelligent Production Innovation Support Project" supported by the Ministry of Industry, Trade and Energy and managed by the Korea Research Institute of Small and Medium-sized Shipbuilding (RIMS). It is the first new technology adopted in South Korea.

Hull marks refer to a variety of words and marks engraved on the outer plates of ships for the purpose of ship operation and maintenance. Generally, they are marked at corresponding positions by welding hollow characters or protruding steel characters welding. Weld bead formation. This operation has traditionally relied on manual operation, which is time-consuming and has uneven weld beads.

The automation equipment jointly developed by K Shipbuilding and Doosan Robotics is to mount a collaborative robot on a traveling trolley. The visual sensor mounted on the trolley identifies and writes the position of the reference point, and then marks the input text through the collaborative robot. Welding is performed automatically.

According to K Shipbuilding, as the first technology adopted in Korea, this equipment can ensure high-quality welding beads and shorten the operation time in an epoch-making manner. After K Shipbuilding conducted a trial operation of the equipment, it passed the final acceptance and demonstration evaluation of the project, and its technology was recognized by the competent authority.

K shipbuilding related personnel said: "In the future, the company will also apply this collaborative robot to fields such as material welding or narrow area welding, and contribute to improving production efficiency through the improvement of work processes."

According to reports, K Shipbuilding Company has been actively promoting smart manufacturing in recent years. In 2022, the company also participated in the intelligent production innovation support project for small and medium-sized shipbuilding companies, and used industrial robots in the brazed casing (LUG) production project to achieve automation
