Shielding Gas Screen Torch for Laminar Weld Gas Flow

The patent employs a gas lens with a porous structure containing multiple channels that distribute shielding gas in a controlled manner. This porous configuration transforms the gas flow pattern from turbulent to laminar, ensuring stable protection of the weld zone without causing porosity or disruption to the weld pool.

The patent changes the flow distribution parameters by introducing a gas lens with specifically designed channels. This modifies the velocity profile and flow characteristics of the shielding gas, converting high-velocity turbulent flow into lower-velocity laminar flow that maintains weld quality while providing adequate shielding.

The gas lens utilizes a porous structure with multiple channels to distribute shielding gas efficiently. This configuration maintains effective shielding coverage while reducing the overall gas consumption by optimizing flow distribution and eliminating excessive gas discharge associated with turbulent flow patterns.

The patent optimizes gas flow parameters through the lens design, achieving effective shielding at lower flow rates. The controlled laminar flow pattern maintains protective coverage without the excessive consumption associated with high-velocity turbulent flow, thereby reducing operational costs.

The gas lens with its porous channel structure creates a stable laminar flow that forms a consistent protective barrier. This laminar flow pattern prevents atmospheric contamination by maintaining a stable gas column that resists mixing with surrounding air, unlike turbulent flow which draws reactive gases into the shielding zone.

The patent modifies flow parameters to achieve laminar flow conditions that maintain a stable shielding gas column. This stable flow pattern prevents the incorporation of atmospheric contaminants that occur with turbulent flow, ensuring pure shielding coverage without introducing harmful reactive gases.

The gas lens employs a porous structure with integrated channels that inherently control flow distribution. This design achieves laminar flow without requiring complex external flow control mechanisms, as the porous structure itself provides the necessary flow regulation through its geometric configuration.

The gas lens serves multiple functions simultaneously: it distributes shielding gas, controls flow patterns, and maintains laminar flow characteristics. This multi-functional component achieves flow control without adding separate dedicated flow control devices, thereby limiting the increase in overall system complexity.
