桥检车桁架臂焊接变形的控制

Control of welding deformation about the trusswork of bridge inspection truck

研究了一种新型桁架式臂体桥梁检测作业车的桁架臂矩形钢管拼焊的焊接顺序。通过反复验证,确定了桁架臂生产的最佳装配和焊接顺序,并采取了各种焊接变形控制措施,大大缩短了生产周期,有效控制了生产过程中的焊接变形,减少了矫正变形工作量,对同类结构件的焊接生产具有实际借鉴意义。

A bridge inspection truck with truss boom is worked out in our company. The length of each truss boom is ten meter long,and is putted together with every rectangular steel tube. By many times test,we fixed on a best order of assembly and welding,as well as taked all ways to control the welding deformation actively. By the adjusted technics way,production cycle is cutted greatly,and the welding deformation is reduced availably,and the follow- up work to rectify the deformation is cut down greatly. There is effective meaning of use for reference to the similar welding structure.
