Exploring the Pros and Cons of Handheld Laser Welding
Delve into the realm of handheld laser welding machines with insights from MORN LASER. Discover the advantages and disadvantages shaping the landscape of modern welding technology.
Advantages of Handheld Laser Welding:
- Reduced heat input, minimizing metallographic changes and deformation.
- Verification for 32mm thick single pass welding, saving time and filler metal use.
- No need for electrodes, eliminating concerns about pollution or damage.
- Easy focus, alignment, and guidance of laser beam, allowing flexibility in placement.
- Suitable for welding in closed spaces, under vacuum or internal gas environment control.
- Precision in focusing laser beam enables welding of small and closely spaced parts.
- Versatility in weldable materials, facilitating joining of various dissimilar materials.
- High-speed automation with digital or computer control.
- No reflow issues when welding thin materials or small-diameter wires.
- Unaffected by magnetic fields, allowing accurate alignment of weldment.
Additional Features:
- Welding of metals with different physical properties.
- No need for vacuum or radiation protection.
- Achieving a depth-width ratio of 10:1 with perforation welding.
- Capability to transmit laser beam to multiple workstations.
Disadvantages of Handheld Laser Welding:
- Need for accurate positioning of weldment within the laser beam's focusing range.
- Fixture usage requires precise alignment of weldment with laser impact spot.
- Limited maximum weldable thickness (not suitable for penetration thickness exceeding 19mm on the production line).
- Altered weldability of highly reflective and thermally conductive materials like aluminum and copper.
- Use of plasma controller required for laser beam welding with medium to high energy.
- Rapid solidification of weld bead may lead to concerns about porosity and embrittlement.
- Expensive equipment.
