Portable Laser Welders: A New Frontier in Precision Welding
As a DIY enthusiast and my Leroy Merlin experience, today I bring you a complete article about industrial laser welders, a technology that is revolutionizing the precision and safety of our most demanding projects. Portable laser welding machines are very reasonably priced compared to fixed industrial laser welders.
What is Industrial Laser Welding?
The industrial laser welding It uses a high-power coherent light beam to melt and join metals with millimeter-precise control. Unlike conventional welding, lasers concentrate energy into a tiny spot, reducing residual heat and temperature-affected areas.
Advantages of Precision Laser Welding
- Welding of Maximum accuracy in a millimeter cord.
- Reduction of deformed of the pieces.
- Security improved thanks to interlocking systems and optical protection.
- Less need for finishing and post-weld cleaning.
- Increase in the productivity in industrial environments.
- Ability to weld difficult metals (special steels, titanium).
- Portability in compact equipment for on-site repairs.
- Easy integration with robotics and automated production lines.
Technology and operation of laser welding
Fixed industrial laser welding machines consist of:
- Laser source (fiber, CO₂, neodymium)
- Focusing optics to converge the beam
- Protection systems and smoke extraction
- Control CNC the manual
- Refrigeration system
The laser's power and pulse duration are adjustable according to the material (steel, aluminum, copper), ensuring flawless fusion.
Types of laser welding machines
- Fiber laser: high efficiency and lower maintenance.
- CO₂ laser: good penetration but larger size.
- Neodymium (Nd:YAG): Excellent for reflective metals.
- 3-in-1 Portable Laser: cutting, welding and rust removal in a single unit.

Wires Suitable for Laser Welding
Not all of these threads are equally suitable for the precision laser weldingFor this process, we seek a solid wire with optimal deoxidation, low impurity content, and very stable melting behavior. I'll detail which ones are recommended and why:
- ER70S-6 (AWS A5.18) / G3Si1 (EN ISO 14341-G)
- Recommended ✔️
- Its formulation with silicon, manganese and aluminum (and sometimes titanium) provides a very clean bath and uniform fusion, ideal for the concentrated laser beam.
- ER70S-5
- Can be used with caution ⚠️
- It provides more deoxidizers (Si+Mn+Al) and offers good stability, but its aluminum particles can cause slight inclusions if the heat input is not precisely controlled. It is only suitable for highly tuned pulse laser equipment.
- ER70S-4 / ER70S-3
- Less recommended ❌
- Its lower deoxidizer content and larger particle size in the internal flux tend to cause more spatter and oxide zones that interfere with the laser beam, affecting the quality of the bead.
- ER70S-2
- Not recommended 🚫
- Designed for very clean MIG sheet metal, its low deoxidizer content does not guarantee sufficient protection of the weld pool from the speed of the laser pulse.
- High quality steel MIG wire
- for gas shielded welding of carbon, weakly alloyed or unalloyed steels
- Good thread resistance to corrosion
- Connection cable
- Requires additional parts for use
- Diameter: 200 mm
- Excellent priming properties
- High arc stability at high currents
- Good resistance of the wire to corrosion
- High-quality welding wire for almost all MIG/MAG devices with a 50 mm mandrel.
- Unalloyed solid wire electrode for universal use and all steel work with shielding gas.
- Low sparks due to high chemical purity for excellent welding results.
- For Telwin welders
- Compatible with welding machines from other brands.
- For welding with shielding gas
Recommendation: For precision laser welding choose preferably ER70S-6 (or its European equivalent, G3Si1). If your machine allows for very fine pulse and gas adjustments, you could try ER70S-5, but always perform quality tests beforehand. The other wires (S-2, S-3, and S-4) don't provide the bath cleanliness or fusion consistency required by a focused laser beam.
With these recommendations for the best value industrial laser welders, you have versatile solutions at your fingertips for welding everything from delicate metal components to more demanding structures. Now all that's left to do is assess your specific needs—power, portability, or extra features—and decide which of these industrial laser welders best suits your workshop or high-precision home project.
Explore the features of these affordable laser welding machines and choose the one that best suits your workshop or DIY project.
