Cross-welding column and booms and the welding roller frame are used to complete longitudinal and circumferential surfacing of internal wall of large cylinder shell, and the narrow gap welding of vertical circumferential weld inside and outside cylinder shell. DIG's narrow gap submerged arc welding system is a set of closed-loop submerged arc welding system that can accurately realize narrow welding butting.The minimum end of I-type slope submerged arc welding can be narrow to 18mm with the depth of the welding torch reaching 350mm. When the plate thickness is 50mm, the welding efficiency of I-type slope submerged arc welding is 0.5 times higher than that of ordinary submerged arc welding. When the plate thickness reaches 200mm, the efficiency can be increased by at least 1.5 times.

Urban subway is mostly made of stainless steel and the main welding processes are mainly plasma welding, TIG welding, MIG welding, resistance welding and so on. The welding of large parts usually uses gantry robot welding system with dual-computer coordination mode configured with error compensation and welding seam tracking. The welding of carriage body assembly uses special machine while the welding of roof with side wall uses gantry welding.   

Friction stir welding and MIG welding process are used for high-speed rail body parts welding. The friction stir welding process adopts mobile gantry structure and is equipped with laser welding seam tracking and constant pressure constant position control system. MIG welding process adopts mobile gantry equipped with robot.    

We have a series of welding products such as narrow gap submerged arc welding, narrow gap TIG welding, narrow gap MIG / MAG welding, electroslag welding, and strip surfacing. We also have a series of auxiliary machines such as welding column and booms, welding rollerbeds, welding positioner, and welding milling and filling machine. There are complete set of solutions including mature nuclear power rotor welding, hydrogenation reactor assembly and welding.

There are different process options for different ship types. The processes usually include joint plate welding, line cutting and grinding, stiffener assembly, stiffener welding, parts (T-row, ribbed plate,casing) assembly, parts (T-row, ribbed plate, casing) welding, outfitting, lifting and delivery etc.               The Thin Panel Production Line for Luxury Cruises The core technology of thin plate welding is very clear —achieving good productivity with the minimum deformation. Based on long-term experience and continuous innovation, DIG has several effective single-sided and double-sided molding or double-sided welding solutions. The application of laser MIG composite welding, double-wire MIG/MAG, thin-wire submerged arc welding and other processes and the coverage of fully automatic control and informatization have brought more accurate quality and higher efficiency to shipbuilding.     Solution of Block Welding by Both Sides on Medium-Thick Plates In the construction of medium-thick plates, high-quality welding seam can be obtained by using the double-sided SAW or MIG/MAG welding process. Using hydraulic mechanical method to roll over or travelling crane to roll over depends on budget and layout for which we have relatively rich experience.   Solution of Both-Side Molding by Single-Side Welding on Medium-Thick Plates The application of FCB or FAB method in the construction of medium-thick plates can accomplish double-side molding by single-side welding. In the construction of thick plate, it is also a good choice. Compared with double-sided welding, double-side molding by single-side welding requires no turning process; however, it usually requires a maintenance pit to repair the reverse side which requires sufficient negotiation and communication between both parties.
