摘要
目前我国高速列车铝合金车体主要采用MIG自动焊接,为实现自动焊接,要求焊丝尺寸精,且具有一定的刚度。国内生产的铝合金焊丝存在严重的质量不稳定问题,高速列车的铝合金焊丝尚依靠进口。为实现高速列车用铝合金焊丝的国产化,本论文针对目前高速列车使用的ER5356及ER5183铝合金焊丝,开发了铝合金光亮焊丝生产工艺。
At present our country＇s high-speed aluminum alloy train body mainly used the automatic MIG welding. In order to realize automatic welding, welding wire must be accurated in size, and it has certain stiffness. Domestic Al-alloy welding wires have serious quality problem, so high-speed train aluminum alloy welding wire still relies on imports. In order to realize the localization of Al-alloy welding wires, this thesis aims at ER5356 and ER5183 aluminum alloy welding wire used in the high-speed train and develops the production process of aluminum alloy welding wires.
