Crane welding
The model of welding rod is E4303(J422) E4316(J426) E5003(J502) E5015(J507) E5016(J506). E4303 E5003 slag with good fluidity, removal of slag layer is easy and so on. E4316 E5016 arc are stable, process performance is general. All this mainly used for welding of important low-carbon steel structure.

Crane painting
Primer spray will be painted immediately after shot blast to avoid rust of the surface. Different paint will be used according to different environment, and also different primer will be used on the basics of different final coat.
Process flow
Crane metal cutting
Cutting method:CNC cutting, semi-automatic cutting, shearing and sawing. Processing department will choose the appropriate cutting method, draw up procedure card, put in program and number.
After connecting, detection and leveling, draw cutting lines according to the required shape, size, cut them with semi-automatic cutting machine.
Process flow
Crane inspection
Flaw detection: butt weld seam will be detected according to requirements because of its importance, grade is no lower than II regulated in GB3323, when detected by ray,  and shall be no less than I regulated in JB1152 when detected by ultrasonic. For unqualified parts, shaved by carbon arc gouging, re-weld after cleaning.
Process flow
Crane installation
Assemblage means assemble each parts according to requirements. When main girder and end carriage are connected into bridge, assure that distance between center of two track and length tolerance of bridge diagonal line meets requirements. When assemble LT and CT mechanisms.
