In modern shipbuilding engineering, welding deformation is one of the core technical challenges affecting structural precision and production cycles. As the global shipbuilding industry transitions toward high-volume and high-precision automation, controlling heat input and compensating for physical deformation through integrated production lines has become a key factor in securing a competitive edge.

Automated panel lines typically begin with a butt-welding station. To achieve excellent productivity while minimizing deformation, industry-leading solutions offer a variety of automated welding options based on advanced arc welding processes.

Currently, proven processes cover both one-sided and two-sided welding stations. By parametrically controlling the welding heat input, consistent and stable penetration can be achieved for various marine steel plate thicknesses, reducing plate warping caused by uneven thermal cycles at the source.

Stiffener mounting and welding represent the most intensive processes in flat block fabrication. Integrating this process into a fully automated station effectively improves assembly precision. The system utilizes separate mounting solutions to position, press and tack profiles, creating optimal conditions for fillet welding.

To further control thermal deformation, automated production lines employ the following strategies:

• Simultaneous Multi-head Welding: Support for multiple welding heads allows for the simultaneous welding of several stiffeners. This synchronized operation not only improves efficiency, more importantly, achieves a balanced distribution of heat, preventing structural distortion caused by continuous welding on a single side.
• Process Flexibility: Support for various welding processes allows for parameter matching based on material range and capacity requests.

Even with advanced processes, large blocks require rigid support during continuous production. Integrating additional auxiliary welding platforms into the line to complete the production solution and minimize residual deformation.

Combined with control software, these hardware facilities create a stable, consistent and parametrically traceable environment. For shipyards seeking long-term reliability, this full-process automation is the inevitable choice to reduce rework costs and enhance quality.

The core value of shipbuilding automation lies in the precise control of thermophysical processes. Through DIG's panel line solutions, shipyards can transform complex welding parameters into stable engineering outcomes, ensuring every panel meets strict geometric tolerances.
