Renamed from “Tianjin Sainteagle Welding Co.,Ltd.” to “AT&SE Welding Materials Co.,Ltd.”

2019

AT&M Technology’s welding division has completed the integration of its welding business with Sainteagle Welding, establishing a distinctive dual-brand operating model.

2011

AT&M Technology has funded the acquisition, officially making Sainteagle Welding a controlling subsidiary of AT&M Technology.

2000

Advanced Technology & Materials Co., Ltd. is listed on the Shenzhen Stock Exchange.

2000

Sainteagle Welding has become China’s first domestically owned flux-cored wire manufacturer to exceed an annual production and sales volume of 1,000 metric tons.

1999

AT&M Technology’s Welding Materials Division undertakes the national-level industrial demonstration project—The Industrialization Project for Flux-Cored Welding Wire—and in 2009 was awarded the “National Ten-Year Achievement Award for High-Tech Industrialization.”

1999

Sainteagle Welding’s self-developed 1,500-ton-per-year and 3,000-ton-per-year flux-cored wire production lines have passed certification.

1998

Advanced Technology & Materials Co., Ltd. Established  Based on the Metal Welding Research Laboratory of the former General Institute of Iron and Steel Research under the Ministry of Metallurgy, Antai Technology Co., Ltd. established its Welding Materials Division.

1994

Tianjin Sainteagle Welding Co.,Ltd. Established A pilot production line for flux-cored welding wire has been successfully developed, enabling the continuous production of 1.2 mm-diameter fine-gauge flux-cored welding wire.  The first batch of titanium-type flux-cored welding wires developed and manufactured has successfully obtained mass-production certification from the China Classification Society. This marks the first domestically produced flux-cored welding wire product in China to receive formal certification from a classification society.

The 1980s

The laboratory has undertaken numerous national key projects in hydrogenation, nuclear power, and other fields, making significant contributions to critical technologies such as China’s first-of-its-kind refining and petrochemical equipment, primary welds in nuclear power plants, stainless steel surfacing, and nickel-based materials. It has also achieved remarkable results in aerospace and other sectors, thereby supporting the independent development of China’s major national equipment.

The 1980s

Tianjin University has established the Welding Research Institute to conduct systematic research on the complete set of production technologies and equipment for flux-cored wires.

1952

The Iron and Steel Research Institute was established, and the Metal Welding Laboratory was set up.
