Laser Weld Penetration: OEM & Customization

At Klear Laser we treat every chassis as a blank forging. Our in-house fabrication team cuts, bends, and welds 3 mm–8 mm carbon-steel or AISI 304 frames to match your plant’s footprint and loading bay limits. We then stress-relieve and machine datum faces so the gantry, JPT or Raycus fiber source, and wobble head stay thermally stable to ±0.05 mm over an 8-hour shift. The result is a rigid, compact skeleton that lets you reach 8 mm stainless penetration without the 30 % power loss seen on lightweight aluminum frames.

Laser power is not a catalogue number for us. We start with your joint geometry and cycle-time target, then pair a 1 kW, 2 kW, or 3 kW JPT MOPA or Raycus continuous source to a 25 µm–100 µm core delivery fiber. Inside the same cabinet we add an extra 20 % headroom on PSU capacity and fit swappable 2-in-1 wobble optics (0–5 mm amplitude) so tomorrow’s thicker chassis parts can still be welded without buying a new resonator.

Our HMI is compiled in CODESYS 3.5 and runs on an industrial ARM IPC mounted on the left door. You get drag-and-drop seam programs, real-time penetration depth calculated from back-reflection, and an open OPC-UA tag set that drops straight into Siemens or Allen-Bradley plants. If you need traceability we can lock every parameter behind barcode-based user levels and auto-generate a pdf report that maps weld depth, plasma plume intensity, and shield-gas flow for each 0.1 mm of travel.

Below is a direct comparison of the penetration achieved with conventional MIG versus our fiber laser on the same 6061-T6 and 304 coupons. The laser values were recorded at 2 kW, 1 m/min with a 2 mm wobble diameter; the MIG values used 1.2 mm ER4043 wire, 28 V, 180 A, 0.5 m/min travel. The table shows why automotive and battery manufacturers are switching to Klear Laser to replace multi-pass arc methods.

By integrating a stiff custom chassis, field-upgradable laser power, and open software architecture, we deliver a welding cell that can grow with your product roadmap while cutting heat input by 85 % and post-weld straightening time to almost zero.

Key Features & Advantages

Klear Laser achieves superior weld penetration through the precise synergy of high-quality fiber laser sources and advanced optical delivery systems. Our machines deliver exceptional energy density directly to the workpiece, ensuring deep and narrow fusion zones. This results in structurally sound joints without the excessive heat input typically associated with traditional TIG or MIG welding processes.

We utilize premium laser sources from industry leaders like Raycus and JPT to guarantee consistent beam quality and long-term stability. These sources provide an excellent Beam Parameter Product (BPP), which allows the laser to focus into an incredibly tight spot size. A tighter spot size significantly increases the energy density per square millimeter, driving the beam deeper into reflective materials like aluminum and conductive metals like copper.

The integration of advanced wobble welding heads is the second critical factor in our penetration capabilities. By oscillating the beam at high frequencies, the wobble function effectively stirs the molten weld pool to release trapped gases and prevent porosity. This dynamic beam movement allows for wider seam bridging while maintaining full-depth fusion, even when the fit-up of the parts is not perfect.

Control systems on our equipment allow operators to modulate the pulse frequency and duty cycle to match the specific thickness of the substrate. This level of fine-tuning ensures that the keyhole effect is maintained for maximum depth without blowing through thin materials. The result is a hermetic seal and a metallurgical bond that exceeds the strength of the base material.

Industrial Applications

Laser weld penetration depth is critical in automotive manufacturing for structural battery enclosures and powertrain components. Deep, narrow welds ensure leak-proof integrity in high-voltage battery housings using aluminum alloys. Our fiber laser systems with JPT MOPA sources achieve 6-8mm penetration in 5000-series aluminum, replacing slower, distortion-prone MIG processes. Wobble welding heads optimize bead geometry while minimizing heat input into sensitive electronics.

Aerospace demands extreme penetration consistency for critical rotating assemblies like turbine disks and shafts. Titanium and nickel superalloys require precise 4-7mm penetration depths to meet fatigue resistance standards in jet engines. Klear Laser systems utilize Raycus QCW lasers with real-time melt pool monitoring to prevent under-penetration defects. This replaces electron beam welding in many applications with safer, more accessible laser technology.

Marine industry applications focus on corrosion-resistant welds for ship hulls and offshore pipelines using duplex stainless steels. Deep penetration (5-10mm) in challenging 2205 duplex steel ensures seawater resistance without post-weld heat treatment. Our pulsed fiber lasers maintain substrate safety by controlling heat-affected zone width below 0.5mm. This eliminates costly secondary processes required by traditional submerged arc welding.
