What shielding gas should I use, and what’s the recommended flow rate?
- Supported gas type:
- Nitrogen (gas purity ≥ 99.99%)
- Argon (gas purity ≥ 99.99%)
- Compressed air
- Processing mode: Laser Welding
- Gas setting: Flow rate: 15 L/min – 30 L/min
- Pressure: 0.1 MPa – 0.2 MPa
- Processing mode: Laser Cleaning
- Gas setting: Flow rate: 15 L/min – 30 L/min
- Pressure: 0.1 MPa – 0.2 MPa
- Processing mode: Laser Cutting
- Gas setting: Gas pressure: 600 kPa – 800 kPa
- When the gas supply pathway remains unchanged, the pressure and flow rate maintain a fixed correlation.
- For welding and cleaning, a flow regulator valve is typically required. Set the flow rate to 15 L/min – 30 L/min. If the welding results are unsatisfactory, gradually increase the flow rate and reassess.
- For cutting, a pressure regulator valve is generally required. Adjust the pressure to 600 kPa – 800 kPa.
- Compressed air can be used for both handheld cleaning and cutting. However, the cleaning effect is not as good as nitrogen or argon, the latter cleaning will be more cllean and bright.
How do I set the Scan width for the welding head?
Set the Scan width based on material characteristics and joint requirements:
- Material Properties
- High thermal conductivity (Aluminum, Copper): Use wider oscillation (typically 1.0-2.0mm) to distribute heat and prevent localized overheating
- Low thermal conductivity (Stainless Steel): Narrower oscillation (0.3-0.8mm recommended) concentrates energy for proper penetration
- Joint Gap Requirements
- Narrow joints (<0.5mm gap): Small scan width (0.5-1.0mm) maintains focused energy density
- Wide joints (>1.0mm gap): Wider oscillation (1.5-3.0mm) ensures full coverage and uniform fusion
What should I do if filler wire sticks during welding?
To resolve filler wire adhesion, you can:
- Increase the laser shutdown delay time
- Or decrease the Re-feeding delay.
Why does black smoke appear during welding?
Black smoke during welding can result from several factors:
- Material Properties: Some materials—especially aluminum alloys—are more prone to generating smoke due to their sensitivity and composition.
- Surface Contamination: Oil films, grease, or oxide layers on the material's surface can increase smoke production during welding.
- Welding Wire: Standard welding wires not designed for laser welding may produce more fumes. Low-fume wires are recommended for cleaner welds.
- Welding Technique: Incorrect torch angles, inadequate shielding gas flow rates, or improper power settings can lead to incomplete gas coverage, leading to more smoke.
- Damaged Lens: A damaged lens can scatter the laser beam or arc energy, increasing smoke and reducing overall weld quality.

xTool MetalFab Laser Welder 1200w defaults to Standard mode upon startup. In this mode, users can simply select material type, thickness, and wire diameter to begin welding--ideal for quick setup. For more experienced users seeking greater control, switching to Advanced mode unlocks additional parameter settings, allowing fine-tuning based on specific welding needs.
Can laser welding achieve the same penetration depth as traditional methods when welding 5 mm stainless steel?
With appropriate process parameters, xTool MetalFab Laser Welder 1200W can typically achieve a penetration depth of 5mm or even deeper. The specific penetration depth depends on factors such as the set laser power, welding speed, and focal position.
How can I prevent porosity when laser welding aluminum alloys?
To avoid porosity, you should pay attention to these things:
- Material Preparation: Thoroughly clean the aluminum surface to remove oxide layers and contaminants. Ensure the material is completely dry before welding.
- Parameter Settings: Increase wire feed speed as needed to optimize the welding process and prevent gas entrapment.
- Gas Selection: Use argon as the preferred shielding gas for welding aluminum. While nitrogen can be used under normal conditions, argon is more effective in reducing porosity in this application.
Can xTool MetalFab Laser Welder weld or cut titanium and magnesium alloys?
