Type A double girder crane adopts steel coil coil or seamless steel pipe. Weihua has an industry-leading steel plate coil coil production and processing production line, from 1250t press pre-bending to three-roll coiling machine to round, and then to Automatic welding center welding of simplified longitudinal and circumferential seams and simplified machining of heavy-duty CNC horizontal lathes.

The main beam is the first in the industry to adopt efficient and intelligent welding robots. The inner seam welding of the main beam adopts advanced MAG welding, using Ar+CO2 mixed shielding gas, and the four main welds on the outer side of the main beam are welded by submerged arc automatic fillet welding machine.

The main butt welds and fillet welds of the main girder plates are tested by radiography and ultrasonic testing to ensure the quality of the welds.
