钢结构厂房中的十字型梁没有专门型材,需要两种型材拼焊。由于结构限制,普通埋弧焊接设备无法施焊,且手工拼焊不能保证质量,需要设计专用焊接设备。为了保证十字形梁焊接精度,专用焊机设计前针对定位方式进行误差计算,从而找出合理的定位方式,并制造出专用焊机投入生产,为钢结构厂房中的十字型梁构件的加工方法提供参考。 Steel cross-shaped beam in the workshop there is no special profile, need two profiles welding. Due to structural limitations, ordinary submerged arc welding equipment can not be welded, and manual welding can not guarantee the quality of the need to design special welding equipment. In order to ensure the welding precision of cross-shaped beam, the special welding machine is designed to calculate the error for the positioning method before positioning so as to find a reasonable positioning method and manufacture a special welding machine to put into production for the processing method of the cross beam member in the steel structure workshop for reference.
