During TIG welding of aluminum alloy spiral welded pipes, the high fluidity of the melt pool and severe arc reflection make it difficult for welders to directly assess penetration status. The introduction of a melt pool monitoring weld camera provides a clear, magnified view of the molten pool and tungsten region, effectively filtering out arc glare and enabling real‑time on‑screen monitoring of weld formation.

Key advantages:

• Improved weld quality – Captures melt pool edges, penetration depth, and oxide layer rupture clearly, allowing timely parameter adjustments to reduce defects such as porosity and lack of fusion.
• Enhanced welder safety and health – Eliminates the need for close direct observation of the arc, significantly reducing eye and skin exposure to UV and IR radiation.
• Lowered skill requirements – Enables novice welders to intuitively understand melt pool behavior through the screen, accelerating skill acquisition and reducing trial‑and‑error costs.
• Process traceability – Supports video recording for subsequent quality analysis and process optimization.

By adopting a melt pool weld camera, the production of spiral welded pipes becomes more stable, safer, and more efficient.
