Snail Tools | AS20D Series M16 Laser Welder Nozzle for Dual Wire and High-Flow
The Snail Tools AS20D Laser Welding Nozzle is a crucial consumable engineered for North American automated and specialized fabrication that utilizes Dual Wire Feeding technology. This nozzle is characterized by the ‘D’ designation, indicating a specialized internal channel design to manage two filler wires simultaneously, a process critical for maximizing deposition rates and bridging wider gaps.
Key Features for North American Manufacturing Success:
-
Dual Wire Feed Capability: The ‘D’ (Double) design is essential for specialized welding heads, maximizing deposition rates and providing material flexibility in a single pass.
-
Versatile Wire Guiding: The aperture is often designed to fit , , and wires when run in a double-feed configuration, accommodating various job requirements.
-
Weld Clean Application: The nozzle’s design and copper material properties are highly suitable for use during the integrated Weld Clean (pre- and post-weld surface treatment) function of advanced laser heads.
- M16 Thread & 32mm Length: Standard dimensions ensure a secure, high-concentricity fit across compatible M16 laser welding systems.
- High-Flow Gas Shielding: The large internal diameter ensures a robust curtain of inert gas to protect the large weld pool from atmospheric contaminants.
