In 2005, the Company developed and manufactured the gas shielded welder, which has been successfully applied to the continuous strip steel production line.
After years of continuous exploration and research, the gas shielded welder products have been put into use in large quantities and operate stably on the customer sites, which is deeply recognized and praised by customers in the industry.
Kaiqi "NZ series" argon shielded arc welder has won provincial and municipal scientific progress awards many times.

In 2012, the company developed and manufactured the hybrid welder, which has been successfully applied to the continuous strip steel production line.
The welder breaks through the traditional design concept, integrates the advantages of "gas shielded welding" and "lap welding", and integrates the latest self-designed process control technology, which can meet the welding needs of users for cold (hot) rolled plates on one production line. The product has strong adaptability to the variety change of strip steel, wide universality, and is very suitable for the needs of this kind of production line.

In 2010, the Company developed and manufactured laser welder, which has been successfully applied to the continuous steel strip 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 taken the lead in applying solid laser welding technology to hot-rolled plate and strip production lines. The welder has the advantages of high efficiency, energy saving, stable welding, simple operation and maintenance and low cost. It has been put into use in large quantities, covering all production lines in the plate and strip cold rolling industry, and is deeply recognized and praised by customers in the industry.
"GD series" high-power solid (optical fiber) laser welder and "GQ series" high-power gas (CO2) laser welder have obtained the technical achievement appraisal certificates.
