根据EN 10225-2009标准要求,结合实际生产需求,制定合理的FACW对接工艺并进行焊接,分析焊接接头显微组织(金相组织)及性能(拉伸、冲击、弯曲、硬度),并进行综合力学性能的评定,推荐合适的焊接工艺范围。
According to EN 10225-2009 standard requirements, combined with the actual production requirements, formulate reasonable FACW butt welding process, analyze the microstructure (metallographic structure) and properties (tensile, impact, bending, hardness) of welding joints, and evaluate the comprehensive mechanical properties, recommend the appropriate welding process range.
