随着高速铁路技术的不断成熟,从牵引系统、各种构件到车体的焊接,从低碳钢、低合金钢、高强钢、不锈钢到铝合金,从焊条电弧焊、埋弧焊、气保焊、接触焊、搅拌摩擦焊到机器人和智能化焊接,在高速列车制造及轨道建设中都得到很大应用。在此,我刊专门开辟“高速列车及轨道先进焊接技术”专题,旨在推广高速列车及轨道焊接中的先进技术,为全面提高铁领
With the continuous development of high-speed railway technology, from the traction system, various components to the body of the welding, from low carbon steel, low alloy steel, high strength steel, stainless steel to aluminum alloy, from the arc welding, submerged arc welding, Welding, contact welding, friction stir welding robots and intelligent welding, high-speed train manufacturing and track construction have been great applications. Here, I published a special “high-speed trains and tracks advanced welding technology” feature, designed to promote high-speed train and rail welding in the advanced technology, to raise the overall iron collar
