Experts at the Shandong Academy of Sciences have recently solved key problems in sea welding techniques that can diminish the sector's heavy reliance on foreign technologies.

The proprietary technologies meet international standards and will be used for ocean engineering, oil rigs and submarine manufacturing, according to Wang Juncheng, the academy's vice-director.

The academy is now establishing China's first industrial zone for production of ocean welding materials and equipment.
