天圆地方型吊机基柱的焊接工艺方案

Welding Process Scheme of Tian-yuan-di-fang Typed Pillar of Crane

为了控制基柱的焊接变形和装配精度,针对天圆地方型吊机基柱的焊接工艺方案,通过灵活运用刚性固定工装、反变形法及焊后校正法,在制作过程中严格控制下料、坡口设计、焊接顺序设计、装配顺序设计以及焊接方法选择等工艺环节,规范了法兰、直筒体、天圆地方结构件及三者总装的工艺。

In order to control the welding deformation and assembly precision of the pillar,the welding process scheme of Tianyuandifang type pillar of crane was discussed. By using the rigid fixed tooling,anti deformation method and post welding correction,the production processes of blanking,grooving,welding sequence,assembly sequence and welding method selection were strictly controlled,so as to standardize the process scheme of flange,straight tube body,Tianyuandifang structure and assembly of the three structures.
