摘要
大型游乐设备的机械部件(如曲柄)设计和选用中,涉及使用的材料一般只考虑经济性、适合性和方便易采购。为获得具有一定塑性、韧性和强度较高的优良综合力学性能的焊接接头,会涉及到异种钢的焊接,异种钢的焊接工艺是处理和获得材料性能稳定过渡的关键技术。焊接工艺评定过程的实施是对拟定的焊接工艺规程进行验证和今后对生产中焊接工艺规程的制定依据。
In the design and selection of mechanical components of large-scale amusement equipment,such as cranks,the materials used are generally considered only for economy,suitability and convenience.In order to obtain welded joints with high plasticity,toughness and strength,the welding of dissimilar steels will be involved.The welding technology of dissimilar steels is the key technology for processing and obtaining stable transition of materials.The implementation of welding procedure qualification process is the basis for validating the proposed welding procedure and formulating the welding procedure in production in the future.
