Overcoming Shipbuilding Pain Points with Intelligent Welding and Cutting Equipment

The shipbuilding industry has long been constrained by challenges such as the processing of irregularly shaped medium-to-heavy plates, complex weld configurations, a significant shortage of skilled welders, and high rework costs. Wuxi Zhouxiang—a national-level "Little Giant" enterprise recognized for specialization, refinement, uniqueness, and innovation—has dedicated 35 years to the welding and cutting equipment sector. Leveraging nearly 50 invention patents, the company has developed a comprehensive suite of specialized robotic welding solutions for shipbuilding. These solutions cover a wide range of hull components—including sub-assemblies, flat blocks, and T-profiles—thereby facilitating the intelligent transformation of shipyards.

For ship sub-assembly components such as T-bar longitudinals and deck stiffeners, Zhouxiang’s multi-torch gantry welding system enables the simultaneous welding of multiple profiles; combining hydraulic synchronous clamping with real-time seam tracking and correction, it doubles efficiency compared to traditional single-unit setups and achieves a weld NDT pass rate exceeding 99%. Designed for large flat panel blocks, the gantry and cantilever welding robot workstations feature a 3D line-scan vision system that eliminates the need for manual teaching; by directly importing 3D ship models for automatic path planning, the system autonomously compensates for assembly errors of up to 30mm, reliably executing complex welds—including flat, vertical, and corner welds—in a continuous, 24-hour production environment.

For high-risk work areas such as double bottoms and narrow engine room compartments, Zhouxiang’s lightweight, magnetic-adhesion collaborative robot offers flexible deployment; it can be positioned and set up by a single operator, replacing manual welding tasks performed at heights or in confined overhead spaces, thereby significantly reducing safety hazards.

Field data from shipyards demonstrates that Zhouxiang’s shipbuilding equipment reduces block construction time by 30% and cuts overall labor costs by 40%, while significantly reducing the need for grinding and the consumption of consumables for rework. We provide comprehensive, integrated services—including equipment customization, process testing, on-site commissioning, and lifelong maintenance—empowering smart shipbuilding with professional, intelligent welding and cutting equipment.
