H型钢结构焊接过程中变形的控制

Control of Welding Deformation with H-Shaped Steel

针对钢结构焊接变形的产生原因,提出了在 H 型钢焊接制作过程中采取预留收缩量、反变形施焊、制定合理的焊接工艺、预制上拱度等措施以控制变形,同时对挠曲变形、拱变形、角变形的矫正方法作了初步的探讨。

Effective measures such as adding shrinkage beforehand, reversible deformation welding, working out reasonable welding processes and making camber in advance etc. are put forward to control deformations caused by welding of welded H- shaped steel, and various methods of correcting curve deformations, camber deformations and angular deformations are introduced.
