Qingdao Haiyue Electromechanical Technologies Co., Ltd

Our History

Qingdao Haiyue Electromechanical Technologies Co., Ltd was established in September 1996 in the Jimo automobile town. As a former subsidiary held by Haerbin Institute of Technology, Haiyue was of a high technical starting point from its early stage. After restructured in 2004, it is now a high-tech enterprise focusing on the development and manufacture of inverter welding power source, industrial automatic control equipment, medium-high frequency induction power, and automatic welding equipment.

In the past two decades, Haiyue has actively explored the application of induction heating technologies. In order to response the specific heating demands coming from heavy equipment companies, the company has been focusing itself on the development of medium and high frequency induction heating technologies, and successfully applied its products in fields of nuclear power, offshore engineering, electric power, boiler and pressure vessels, shipbuilding, steelmaking, and petrochemical equipment.

For hundreds of technical service projects have been accomplished, abundant of experiences on technology research and development are accumulated. Based on these experiences, personalized service and products are designed, which are identified and welcomed by most large and super-large equipment manufactures at home and abroad.
Although Haiyue have been authorized dozens of invention patents, the company does not stop its pace of scientific and technological research and development. In recent years, Haiyue has been actively taking part in national standards drafting and experimental validations of heat treatment in heavy industries.
