The Company researched,developed and manufactured its first gas shielded welding machine in 2005, which was successfully applied in the strip steel production line.
Thanks to years of unceasing exploration and research, the gas shielded welding machine has been used in batch, operated stably at the worksite and well recognized and praised by the users in the industry.
The "NZ series" gas shielded welding machine of Wuhan Kaiqi has won provincial and municipal scientific progress awards for many times and various national invention patents and national utility model patents.

The Company researched,developed and manufactured its first hybrid welding machine in 2012, which was successfully applied in the continuous strip steel production line.
The welding machine breaks through the traditional design concept, integrates the advantages of "gas shielded welding" and "lap welding", and applies the latest self-designed process control technology, which can meet the welding needs of users for cold-rolled (hot-rolled) plates on one production line. With strong adaptability to changes in strip steel varieties and wide applicability, the product is highly adaptable to the needs of this kind of production line

In 2010, the Company developed and manufactured its first laser welding machine as the first example of laser welding machine localization, which has been successfully applied to the continuous strip steel production line.
After more than ten years of continuous exploration and research on the core technology of laser welding, the Company has broken through the traditional laser welding technology at home and abroad, and successfully applied solid laser welding technology to strip steel continuous production lines in 2012. The solid laser welding machine offers stable welding quality and is more efficient, energy-saving, cost-effective, easier to operate and maintain than traditional gas laser welding machine. It has been put into use in large quantities for all production lines in the strip steel cold rolling industry, and is deeply recognized and praised by customers in the industry.
The "GD series" high-power optical fiber (solid) laser welding machine and the "GQ series" high-power CO2 (gas) laser welding machine have won scientific and technological progress awards for many times and various national invention patents and national utility model patents.
