Introduction to Handheld Laser Welding Machine Nozzles

In a handheld laser welding machine, nozzles play a critical role in delivering high-quality welds. The nozzle is the part at the end of the welding head that guides the shielding gas (such as argon or nitrogen) and helps focus the laser beam onto the workpiece. It also protects the optics from spatter and dust.

Types of Nozzles:

1. Single Hole Nozzle

• Directs shielding gas in a straight line.

• Ideal for straight welds and general-purpose applications.

2. Double Hole Nozzle

• Provides better gas coverage on both sides of the weld.

• Useful for thicker materials or where oxidation is a concern.

3. Nozzle with Wire Feeder Port

• Used when filler wire is added during welding.

• Allows for simultaneous wire feeding and gas protection.

4. Angled Nozzles

• Designed for hard-to-reach areas or corner welding.

• Helps maintain gas flow and beam direction in tight spaces.

Functions of the Nozzle:

• Ensures proper shielding gas flow to protect the weld area.

• Helps maintain a stable and focused laser beam.

• Reduces spatter and contamination.

• Improves weld appearance and quality.

Maintenance Tips:

• Clean nozzles regularly to avoid blockage.

• Replace worn or damaged nozzles to maintain performance.

• Use the correct nozzle size and type based on the material and welding technique.
