Taicang startup makes breakthroughs in laser welding
Tonggao Advanced Manufacturing Technology Co Ltd, a start-up from Taicang in East China's Jiangsu province, has made a name for itself due to its innovate laser welding methods.

Tang was admitted to Tongji University in 1997 and after graduating he started working for world-renowned Dürr Paintshop Systems Engineering (Shanghai) Co., Ltd and Comau Shanghai Engineering Co Ltd for whom he did research and development, management and maintenance services for projects in South Korea, Thailand, India, Japan and Australia launched by auto suppliers such as General Motors, and Ford Motor Co. Tang received his doctorate from France's Grenoble Academy in 2014.
"Taicang is a great place for start-ups," Tang said. "It is home to more than 200 German-funded enterprises. So here we received capital and technologies to start our own business."
In 2014, Tang started working in R&D in new laser welding and reverse engineering technologies with teams of experts in robotics, laser technology and control sectors.
"Laser welding achieves more efficient, precise welding using a high-efficiency atomic battery device to produce high energy density laser beams," Tang explained.
In contrast to electric and arc welding technologies, laser welding ensures higher security and quality, and allows vehicles to be lighter., making it popular in the high-speed rail and aerospace fields.
"Usually, a couple of robots weld at the same moment in a limited space, and quite often robot arms crash into each other," Tang said. "And clients have not able to fix this problem."
To correct this fault, Tang and his team did a lot of research in combine robots and laser workstations and eventually developed computer simulation technology by mixing and processing a number of complex automatic devices through high-power laser technology. This system enables robots to in close precision without interfering with each other.
With its superior capacity in R&D, the company finished 10 successful projects in two years, won seven licensed patents, including three for inventions, and established close ties with MBE of the United States, Germany's ThyssenKrupp and Laserline, China's CNR Corporation Limited and Shanghai SAIC Motor.
Tang has promised to promote laser welding technology and the high-end equipment manufacturing industries throughout the Port of Taicang.
