On June 12th, 2018, an automatic welding robot was set in Qingdao Hesheng's production line. All welding robots have finished commissioning and prepared well to work in welding area. We keeps the aims of controling product quality strictly, improving production capacity continuously, doing our best to meet customers' requirements. This time we chose the welding robot to replace traditional manual welding. Because of its advantages such as stable weldability and 24-hour continuously working can eliminate poorly welding quality and low efficiency by manual welding. The use of welding robot provides an effective guarantee for delivering big volume equipment orders on time by Qingdao Hesheng.
