Laser Welding FAQs
About NOVAWELD™ Handheld Laser Welding
What is laser welding?
Laser welding is a metal joining process that uses a high-energy, focused laser beam to fuse materials with precision and minimal heat input. Compared to MIG or TIG welding, laser welding creates deeper penetration, narrower weld seams, and less distortion. NOVAWELD handheld laser welding machines bring this industrial technology into a portable system capable of welding, cutting, and cleaning.
Is laser welding easy to learn?
Yes. Laser welding is usually easier to learn than MIG or TIG welding. NOVAWELD systems include built-in welding presets and adjustable parameters, which allow beginners to produce clean, consistent welds quickly. Proper joint preparation and material setup are still important for the best results.
Is laser welding safe?
Laser welding is safe when proper precautions are followed. Safety requirements include laser-rated eye protection (OD 6+), protective clothing, controlled work areas with curtains or enclosures, and adequate ventilation. NOVAWELD machines also include multiple built-in safety systems to prevent accidental laser exposure.
How is laser welding different from TIG or MIG welding?
Laser welding offers several advantages over MIG and TIG welding, including faster travel speeds, cleaner welds, deeper penetration, and minimal post-weld cleanup. NOVAWELD laser welding machines can weld stainless steel, carbon steel, aluminum, galvanized steel, brass, and copper. For very thick materials, traditional welding methods may still be preferred.
Why are laser weld seams so small?
Laser welding produces narrow seams because the laser beam is tightly focused into a very small area. This results in deep penetration, high strength, and reduced heat-affected zones. NOVAWELD systems also support wobble welding to widen seams and improve gap-bridging when needed. The narrow seams make laser welding well-suited for vertical, horizontal, and overhead positions. The small weld pool, reduced spatter, and lightweight NOVAWELD welding torch make out-of-position welding easier and more consistent.
What is wobble welding?
Wobble welding is a laser welding technique where the beam oscillates during welding to create a wider seam. This improves gap tolerance and weld consistency. NOVAWELD allows full control over wobble width and frequency.
Does NOVAWELD support pulsed laser welding?
Yes. NOVAWELD laser welding machines support pulsed, spot, and continuous welding modes. Pulsed laser welding is ideal for thin metals and heat-sensitive materials, reducing the risk of burn-through.
How durable are laser welders?
NOVAWELD machines are built for industrial environments with enclosed optics that protect against dust and debris. The rugged design ensures consistent performance in both shop and field conditions.
What is the duty cycle of NOVAWELD laser welders?
NOVAWELD laser welders are designed for continuous operation. The dual-circuit cooling system maintains stable laser output during long welding sessions, unlike air-cooled systems that lose performance as temperatures rise.
What materials can a laser welding machine weld?
NOVAWELD laser welders can weld stainless steel, carbon steel, aluminum, galvanized steel, brass, copper, and certain dissimilar metal combinations.
Do I need special training to use a laser welder?
Most users can begin laser welding within hours using NOVAWELD preset parameters. While formal certification is not required, training is recommended to ensure safe operation and optimal weld quality.
How is NOVAWELD cooling different from other laser welders?
NOVAWELD uses dual-circuit direct cooling technology rather than air or standard water cooling. This allows stable performance across a wide temperature range and supports extended duty cycles without overheating.
Can NOVAWELD replace MIG or TIG welding?
In many applications, yes. NOVAWELD laser welding offers faster welding speeds, smaller heat-affected zones, reduced distortion, and easier operation compared to MIG or TIG welding.
Do NOVAWELD laser welders require shielding gas?
Yes. Shielding gas is required for laser welding. NOVAWELD systems must be connected to a shielding gas source to protect the weld pool and ensure clean, high-strength welds. NOVAWELD laser welders are compatible with Argon, Nitrogen, and Helium. Argon provides the highest weld quality for most applications, while Nitrogen is commonly used for stainless steel.
What safety features are built into laser welding machines?
NOVAWELD laser welders include multiple safety features such as emergency stop buttons, key-switch activation, trigger-based control, internal safety interlocks, and certified laser safety eyewear.
Are NOVAWELD handheld laser welders good for beginners?
Yes. NOVAWELD handheld laser welders are designed for ease of use, and most beginners can be trained to produce quality welds in under two hours.
Does Nuwave Laser offer laser welding demonstrations?
Yes. Nuwave Laser offers on-site and virtual laser welding demonstrations so that customers can evaluate laser weld quality and test materials specific to their applications.
