摘要
轨道车辆不锈钢车体的顶板及地板采用厚度0.8 mm、材质为SUS301L的奥氏体不锈钢薄板滚压成型材焊接而成。为保证车体的密封性、控制焊接变形,波纹板拼接采用全自动电阻缝焊工艺。通过制定试验方法,开发波纹板缝焊工艺,实现了不锈钢波纹板自动、稳定的焊接,大大提升了轨道车辆不锈钢车体的制造水平。
Rolled stainless steel 0.8 mm-SUS301L is used in roof plate and underframe plate of stainless steel railway vehicles, and several plates are welded together.Automatic seam welding is used to weld the corrugated plate for tighting and welding deformation of carbody.Stainless steel corrugated plate can be welded automatic and stable by making test method and developing seam welding process.It improves the manufacture level of stainless railway vehicles greatly.
