As the shipbuilding industry develops towards large-scale, complex and high-precision, the shortcomings of traditional welding processes in efficiency and quality are becoming increasingly prominent. In order to meet the needs of modern shipbuilding for high-quality and high-efficiency welding, Ship robotic welding solutions have emerged. By introducing automated and intelligent robotic welder technology, ship welding is freed from heavy manual operations and moves towards a new stage of intelligent manufacturing.

Industry pain points of ship welding

1. Large welding workload

Ships welding usually requires hundreds of kilometers of welds to be completed. The welding process is complicated and time-consuming, and manual operation is difficult to meet the production schedule requirements.

2. High welding quality requirements

Ship welding not only needs to ensure the strength and sealing of the structure, but also withstands corrosion and impact in the marine environment. The quality of the weld is crucial to ship safety.

3. High labor intensity

Ship welding is usually carried out in high temperature, closed or high-altitude environments. Workers are prone to fatigue after long-term work, which affects welding accuracy and efficiency.

4. Shortage of human resources

The welding industry has an increasing demand for skilled welders, but the long training cycle and insufficient supply of workers have become bottlenecks for the development of the industry.

Ship robotic welding solutions

Ship robotic welding solutions solve the bottleneck problem of traditional processes through automated welding equipment and intelligent control technology, and achieve efficient and high-quality ship welding.

1. Robotic welder configuration

Different types of robotic welders are configured according to the ship structure and welding requirements:

Articulated robot: flexibly adapts to complex welding paths, suitable for precision welding of small and medium-sized ships.

Gantry robot: suitable for linear welding tasks of large ship structures, such as decks and ship plates.

Crawling robot: specially designed for large ship welding, it can automatically crawl on vertical or horizontal surfaces and complete welding.

2. Welding process selection

Gas shielded arc welding (GMAW): suitable for long welds and high-strength welding, used in ship plate splicing.

Submerged arc welding (SAW): fast welding speed, suitable for welding of thick plate structures, such as keels and ship main structures.

Laser arc hybrid welding: Combining the advantages of laser welding and arc welding, it has high welding accuracy, small heat-affected zone, and is suitable for thin plate welding.

3. Intelligent path planning

Through the integration of CAD model and robot control system, the automatic planning of welding path is realized. The robot can adjust the welding angle and parameters according to the complex structure of the ship to ensure the accuracy and quality of the weld.

4. Real-time monitoring and quality inspection

The robotic welder is equipped with a visual system and sensor, which can monitor the temperature, speed and weld shape during the welding process in real time and automatically adjust the welding parameters. In addition, after the welding is completed, the weld is inspected using ultrasonic flaw detection and laser scanning technology to ensure that there are no defects.

Implementation steps

1. Demand analysis and solution design

According to the specific needs of shipbuilding, analyze the difficulties and process requirements of ship welding, and formulate exclusive ship robotic welding solutions.

2. Equipment integration and debugging

Integrate the welding robot, track system, fixture and welding power supply into the production line, complete the welding path programming and equipment debugging, and ensure the stable operation of the equipment.

3. Automated welding execution

The welding robot completes the welding of the main structure, side shell and inner compartment according to the set program.

4. Quality acceptance and optimization and improvement

After welding is completed, the welds are strictly inspected and the process flow is optimized according to the inspection results.

Future development direction

The ship robot welding solution provides efficient and intelligent process support for the shipbuilding industry, helping enterprises to improve product competitiveness and production efficiency. With the application of artificial intelligence and industrial Internet of Things technologies, ship welding robots will be more intelligent and networked. In the future, robots will not only be able to learn welding skills autonomously, but also can be linked with other equipment through cloud technology to achieve intelligent collaboration of the entire production line.
