钢箱梁制作过程质量控制浅谈

箱型结构梁（以下简称箱型梁）作为钢梁的一种结构型式，以其结构新颖、承载能力强、刚性大、稳定性好等优点，在铁路桥梁、公路桥梁、水利电力、工民建等行业的钢结构工程中应用非常广泛。本文主要从下料、拼配、焊接、矫正等工序的过程控制要点，阐述箱梁制作的主要工序和各工序的质量控制。

Shallow Analysis of the Quality Control of the Steel box Girder Fabrication

The structure of box girder （hereafter refers to as box girder） is one kind of structure pattern of the steel gird- er, is novel by its structure, bearing capacity is strong, the rigidity is big, stability good and so on merits, applies widely in railroad bridge, highway bridge, water conservation electric power, labor National Reconstruction Association steel structure projects and so on. This articJe mainly from the main points of process control of working procedure, such as the board alloca- ting, assembles and fits together, welding, correction and so on, elaborated box girder manufactures main working procedure and various working procedures quality control.
