In the manufacturing of engineering vehicles, welding is an indispensable process that directly determines the product’s service life and safety. For tank-type structures such as fuel tankers and cement mixers, weld seams are often long and curved, demanding high precision and consistency. During traditional tank welding, operators find it difficult to observe the molten pool directly, making it hard to detect issues such as weld deviation, incomplete penetration, or poor bead formation in real time.
To address these challenges, Weld Navigator® has developed a welding molten pool monitoring camera system that enables real-time visualization and controllability of the welding process, achieving high levels of automation and stability in tank welding.
I. Principle of the Molten Pool Camera
The Weld Navigator® welding camera utilizes high-dynamic imaging and multi-spectral filtering technology to capture clear and true images of the weld seam and molten pool, even under intense arc light conditions.
With a high-speed shutter and specialized optical filters, the system effectively suppresses arc interference, allowing real-time observation of the molten pool, weld seam centerline, and bead formation.
Combined with Weld Navigator®’s intelligent algorithms, the system not only displays the welding process in real time but also identifies anomalies such as misalignment, porosity, or spatter—providing valuable data for process optimization.
Key Features:
-
Stable imaging under intense arc light; compatible with multiple welding processes (MIG/TIG/laser, etc.)
-
Real-time video monitoring and recording for post-weld quality analysis and traceability
-
Intelligent detection of welding abnormalities for process optimization and automation control
-
Seamless integration with automatic welding systems or robots to enable closed-loop control
II. Common Challenges in Engineering Vehicle Tank Welding
-
Large Workpieces: The large size of vehicle tanks often causes positioning and alignment deviations during welding due to workpiece tolerance and fixture inaccuracies.
-
Molten Pool Visibility: Strong arc light prevents operators from observing the molten pool directly. Manual monitoring relies heavily on experience, and minor defects such as deviation or incomplete penetration are often discovered only during post-weld inspection.
-
Inconsistent Welding Quality: Operator skill differences result in uneven weld appearance and inconsistent quality.
-
Lack of Traceability: Traditional welding lacks video recording, making it difficult to trace the root cause when quality issues occur.
III. Weld Navigator® Visual Welding Monitoring Solution
To overcome these challenges, Weld Navigator® provides a high-precision visual monitoring system that enables complete process visualization and intelligent control in tank welding applications.
-
Real-Time Process Observation
Operators can clearly view the molten pool, weld centerline, and stability on the display screen, significantly improving process controllability. -
Arc Suppression and Stable Imaging
Using proprietary optical filtering and image enhancement algorithms, the system eliminates arc interference and ensures image clarity even in high-brightness welding environments. -
Automatic Detection and Alerts
The intelligent algorithm identifies weld deviation and defects, automatically correcting alignment errors to prevent welding flaws. -
Process Recording and Quality Traceability
The entire welding process is recorded in real time, allowing for quality tracking and process improvement, paving the way for intelligent welding upgrades.
The visualization and controllability of the welding process mark a vital step toward intelligent manufacturing.
Through high-dynamic imaging and intelligent recognition, Weld Navigator® molten pool monitoring camera enables welders to see clearly, control precisely, and trace reliably, solving the “invisible” challenges of traditional tank welding.
Weld Navigator® will continue driving innovation in welding vision technology, helping manufacturers achieve smarter welding and higher-quality production.
