After the material is received, the makeup is arranged at the beginning of the makeup (that is, different parts are processed on a steel plate according to the information of size, quantity and the like, namely, the makeup), and then the material is discharged. Generally, a square plate with the thickness of less than 16mm and a part with a straight line edge are called small parts, blanking is carried out by using a plate shearing machine, a part with the thickness of more than 16mm is called large parts, the large parts and special-shaped parts are blanked by using a numerical control slitting machine, and the small parts with holes on the parts need to be transferred to a drilling machine for punching; the large and small pieces needing to be beveled (the groove with a certain geometric shape which is formed by processing and assembling the parts to be welded of the weldment) are turned to a beveling team to be beveled. All large and small pieces need to be polished, and the large and small pieces of the box type beam column are transferred to a main assembly workshop for assembly after finishing groove polishing; h type, cross beam column then needs to carry out the assemblage operation (also is thick welding) earlier: the assembly workshop carries out rough welding on parts of H-shaped and cross-shaped beams and columns according to requirements: and after the assembly is finished, transferring the assembly to a main assembly workshop for assembly.
