In welding technique sector, we mainly engage in R & D of welding techniques and equipment for stainless steel and aluminum alloy that are used in high-speed train, metro cars and light rail vehicles. We possess a group of advanced welding and cutting machines and/or equipment, such as automatic welding machines for producing longitudinal welds, CNC air plasma cutting machines, aluminum alloy welders from Miller, USA, LVD CNC shearing machines and bending machine from Belgium , large-scale vacuum brazing/soldering welding machines. Products such as aluminum alloy air reservoirs, water tanks, battery boxes, water-cooled radiators, heat exchangers, integrated air passage boards have been developed and successfully applied to high-speed trains and tilting trains.
