Understanding Handheld Laser Welders
“The LIGHTWELD™ 1500 handheld laser welding system enables dramatically faster welding and is easy to learn and operate.” — Linde plc, Global industrial gasses and engineering company
LightWELD represents the most important advancement in welding technology and offers up to 1500W of adjustable laser power for precise control. The system has 74 stored preset modes that help new welders become skilled at the technique within hours.
What is a LightWELD?
LightWELD excels as a handheld laser welding system that delivers high-quality, consistent results with materials of all types. The system has built-in pre-weld and post-weld cleaning functionality and wobble welding controls that work with up to 5mm of additional weld width. The system comes with 100 laser welding and cleaning presets developed to optimize results.
How handheld laser welding works
A high-energy laser beam focuses on a specific area between materials that need joining. The laser power density melts the metal without needing to strike an arc. The hand torch contains a moving mirror that wobbles the beam dozens or hundreds of times per second over the weld joint and melts base material on both sides. This process creates a very narrow, consistent fusion weld bead.
Key components and features
The core components of a handheld laser welder include:
- Laser Source: Uses fiber laser technology with a service life that runs beyond 10,000 hours and consumes less energy
- Cooling System: Uses high-performance military microcontroller technology to manage temperature reliably
- Welding Head: Features replaceable copper nozzles for different welding functions and weighs less than 1.5kg for easy handling
- Control Unit: Controls laser settings through an accessible touchscreen interface
A single cable delivers laser power, gas, and control connections to the gun. The system connects to a computer through ethernet to access advanced parameter settings for fine-tuning process parameters. This technology makes welding speeds up to four times faster than traditional MIG processes and reduces heat-affected zones while minimizing material distortion.
LightWELD vs Other Laser Welders
“In laser welding operations, the heat affected zone (HAZ) is much smaller and the total heat input is much lower than traditional welding operations.” — Titanova, Inc., Laser welding and cutting services provider
LightWELD models stand out from conventional laser welders in several ways. The latest models show clear advantages that make them a cut above traditional welding systems.
Power output comparison
The LightWELD 2000 XR puts out 2 kilowatts of laser power, which is 30% more than previous models. This boosted power creates 6X higher energy density than the original LightWELD 1500. Some stored modes can reach peak power outputs of 2500 watts for specific applications.
Welding speed and precision
LightWELD systems are no match for traditional methods when it comes to speed. These handheld laser welders work four times faster than standard TIG welding. The higher energy density lets newer models penetrate deeper into thicker materials while maintaining quality.
These systems’ precision comes from their focused laser beam technology. LightWELD creates smaller spot sizes that limit the heat-affected zone and reduce distortion in nearby areas. The system has 74 stored preset parameters that deliver consistent results with materials of all types.
Material compatibility
LightWELD shows remarkable versatility in handling different materials. The system works well with:
- Stainless steel and mild steel up to 8mm thickness
- Aluminum 3 & 5 series up to 8mm
- Titanium and nickel alloys up to 7mm
- Copper materials up to 3mm
LightWELD’s ability to join different metals of varying thicknesses sets it apart. The system needs minimal surface prep — metals don’t need much brushing or thorough cleaning before welding. The laser technology works great for vertical and upside-down welding, offering flexibility that traditional methods can’t match.
The system runs at 100% duty cycle at maximum laser power, which means consistent performance during long welding jobs. LightWELD’s wobble welding feature adds up to 5 millimeters of weld width, improving capability and making seams look better.
Safety Features and Training
Safety should be your top priority when using handheld laser welders. These Class 4 laser devices need strict safety protocols and detailed training programs.
Built-in safety mechanisms
Modern handheld laser welders come with multiple protection layers. LightWELD systems have a two-stage trigger mechanism (Figure 1) that will give a safe torch operation. The system has a weld safety detection feature that shuts off automatically when it doesn’t detect a weld plume. Cable safety interlocks also verify stable connections between the laser fiber and welding torch.
The system stays secure from unauthorized use with a key switch and has an emergency stop button for quick shutdown. Laser area interlock circuits stop operations immediately if someone walks into the welding zone.
Required operator training
ANSI Z136.1 standards say organizations using Class 4 lasers must have a Laser Safety Officer (LSO). The LSO makes sure safety protocols work and control measures stay effective. Operators learn several crucial skills through specialized training:
- Laser classification systems and associated hazards
- Safety protocol implementation
- Emergency response procedures
- Equipment maintenance guidelines
Protective equipment needs
You’ll need multiple layers of safety equipment. Operators should wear laser safety eyewear with an optical density (OD) of 7+ at 1070nm wavelength. A certified laser welding helmet adds more protection with specialized lenses that reflect and absorb infrared laser light.
Regular welding gear won’t cut it for laser operations. Here’s everything you need:
- Heat-resistant gloves and flame-resistant clothing
- ANSI Z87+ impact-tested safety glasses under the welding helmet
- Adequate ventilation systems to handle welding fumes
Your workspace needs specific safety features too. A designated Laser Controlled Area should be enclosed by four walls with a magnetic interlock I mentioned above. This enclosure stops laser light exposure up to hundreds of feet away and keep both operators and nearby workers safe. The enclosure needs to also have a roof if your facility’s ceiling has reflective ducts or pipes.
Real Applications and Results
Handheld laser welders show exceptional performance in a variety of materials. These ground examples showcase modern laser welding technology’s versatility and how it streamlines processes.
Laser welding aluminum projects
Laser technology effectively tackles aluminum welding’s unique challenges. The LightWELD XR system excels at welding 5000 series aluminum, including marine-grade materials, without hot cracking problems. Laser welding’s narrower heat path benefits even 6000 series aluminum, which typically cracks with conventional methods.
The system delivers impressive results:
- Full penetration welds on 5052 aluminum up to 6.35 mm thick
- Allows for welding dissimilar materials
- Thermal shrinkage and distortion stay minimal
Stainless steel applications
Laser welding shines when it comes to stainless steel performance. The LightWELD system handles stainless steel up to 6.35mm thickness with complete penetration. This capability serves essential roles in:
- Metal manufacturing industries
- Elevator component fabrication
- Stainless steel stove production
- Frame and window assembly
Industrial Sales & Manufacturing (ISM) tackled a challenging 14-gauge assembly project with laser welding. The technique eliminated extensive prefab fit-up needs and cut post-processing time by a lot. The technology’s precision lets users weld dissimilar metals that have different electrical conductivity.
