金属结构在焊接过程中产生变形是影响结构制造质量的一个主要因素,严格的控制变形措施虽然可以在一定范围内有效地控制焊接后变形,但不能完全杜绝,最终这些残余变形将直接影响工件制造精度和装配质量,因此矫正变形方法的研究和应用是钢结构制造生产实际中的重要课题。目前矫正变形的主要方法有冷矫正(手工或机械矫正)和热矫正(火焰矫正)。而火焰矫正在结构件制造工艺和装配工艺中
Metal structure deformation during welding is one of the main factors affecting the quality of the structure manufacturing. Although strict control deformation measures can effectively control the post-weld deformation within a certain range, they can not be completely eliminated. Ultimately, these residual deformations will directly affect the manufacturing of the workpiece Accuracy and assembly quality, so the research and application of corrective deformation method is an important issue in the actual manufacture of steel structure. The main methods of correction of the current cold correction (manual or mechanical correction) and thermal correction (flame correction). Flame correction in the structure of the manufacturing process and assembly process
