摘要
用TIG自动焊管机以多段脉冲一次成型工艺,对2.5万个规格为φ32mm×4mm、φ42mm×4mm及φ42mm×5mm的锅炉省煤器管子焊口,进行了优质高效焊接。经过生产线上近两年的实践,表明此工艺具有可靠性与实用性。
The high effective ness combined with good quality of joints are achieved using auto-TIG tube welding machine with multisectional pulse current for welding of total 25 thousand economizer tubes in the sizes of φ32mm×4mm, φ42mm×4mm and φ42mm×5mm. The practice in production line for two years proves that the process possesses good reliability and feasibility.
