Laser handheld welding vs. traditional handheld welding: How can disruptive technology improve your production efficiency?
In the field of modern metal processing, innovations in handheld welding equipment continue to drive the industry forward. Traditional arc welding (such as MIG/MIG/TIG welding) has long dominated the market, but in recent years, laser handheld welding technology has become a revolutionary choice for industrial welding with its high precision, low deformation and ultra-high efficiency.
So, what is laser handheld welding better than traditional welding? Why are more and more companies choosing to upgrade? This article will compare the core differences between the two technologies in detail to help you make a more informed investment decision.
***1. Welding principle: heat source and energy control
1. Traditional handheld arc welding (MIG/MAG/TIG)
Heat source: arc (high temperature plasma, temperature ~3000-6000°C).
Filler material: usually requires welding wire (MIG/MAG) or welding rod (MMA).
Large heat input: The heat diffusion range is wide, which can easily cause deformation of the base material.
2. Fiber Laser Handheld Welding
Heat source: high-energy fiber laser (1070nm wavelength, concentrated energy ~1000-2000W).
Non-contact welding: The laser beam directly melts the metal without continuous wire feeding (optional).
Precise temperature control: The heat-affected zone (HAZ) is extremely small, reducing deformation and oxidation.
✔️ Advantages of laser welding: More suitable for thin plates, precision parts and highly reflective materials (aluminum/copper).
***2. Seven core comparisons: Laser welding beats traditional welding?
> Compare Items | Laser handheld welding | Conventional arc welding (MIG/TIG) |
> Welding speed | 2-3 times faster (1-5m/min) | Relatively slow (0.3-1m/min) |
> Thermal deformation | Minimal (concentrated heat input) | Easy to deform (wide thermal diffusion) |
> Welding accuracy | 0.1mm level precision welding | Dependence on welder skills |
> Post-weld treatment | No sanding or little sanding | Need to be polished and deslagging |
> Operability | Easy to use, no years of experience required | Depends on welder proficiency |
> Material adaptability | Stainless steel, aluminum, copper, galvanized sheet, etc. | Some high-reflective materials are difficult to weld |
> Energy consumption | Electro-optical conversion efficiency>30% | Low (arc efficiency ~10-20%) |
***3. Why are more and more companies choosing laser handheld welding?
1. Efficiency increased by 200%+, labor costs greatly reduced
Traditional welders have a long training cycle, while laser handheld welding is simple to operate, and ordinary workers can get started with a little training, greatly reducing the dependence on high-tech welders.
2. Perfect welding of 0.3mm ultra-thin plates, say goodbye to burn-through
Traditional welding is easy to burn-through when welding thin plates, while laser welding can easily weld 0.3mm ultra-thin stainless steel or aluminum plates (such as kitchenware, electronic housings) with ultra-low heat input.
3. Almost no spatter, beautiful welds without grinding
Laser welding has almost no spatter problem, no need for large-scale grinding after welding, saving 30% of post-processing time, especially suitable for industries with high requirements for appearance (such as food machinery, decorative parts).
4. Intelligent control system, one-click parameter call
High-end models are equipped with an intelligent database (which can store welding parameters of different materials) to avoid manual debugging and reduce scrap rate.
***4. What industries are the fiber laser cutting machine suitable for?
✓ Stainless steel products (doors and windows, kitchenware, water tanks)
▶ Laser welding achieves non-discoloration welding and keeps the stainless steel surface beautiful.
✓ Auto parts (exhaust pipes, sheet metal parts)
▶ Low heat input avoids metal embrittlement and improves structural strength.
✓ Electronic hardware (battery connector, precision parts)
▶ Ultra-fine spot (0.1-0.3mm) realizes micro welding.
✓ Pipeline/pressure vessel
▶ Laser deep melting welding ensures airtightness and reduces subsequent inspection costs.
***5. How to choose suitable laser handheld welding equipment?
Power selection:
1000W-1500W: suitable for 1-3mm thin plates (home appliances, decorative parts).
2000W: suitable for 4-6mm medium and thick plates (machinery manufacturing, pipeline welding).
3000W: suitable for 6-8mm thicker plates
Brand and after-sales:
Choose a supplier with a complete after-sales system to ensure long-term and stable use.
***6. Conclusion: The Fiber Laser welding Machine, the future is here!
Traditional arc welding is still widely used, but laser handheld welding is becoming the first choice for manufacturing industry upgrades with its high speed, low consumption and high precision. If you want to improve product yield, reduce labor dependence, and reduce subsequent costs, now is the best time to get into laser welding!
