Laser Beam Welder: Case Study

A Tier-1 automotive supplier in Germany recently replaced its traditional TIG welding line for battery tab connections with Klear Laser’s Fiber Laser Welding Machine. The application involved joining copper to aluminum on battery busbars, where inconsistent welds and heat distortion were common with TIG. After integrating the 1,500W Raycus fiber laser with a wobble welding head, they achieved uniform penetration and zero micro-cracking.

The laser system reduced cycle time from 45 seconds per joint to just 12 seconds. With 3,000 units produced daily, this translated to over 27 machine-hours saved per shift. Operators reported minimal post-weld cleanup, eliminating grinding and rework that previously accounted for 30% of labor time. Material waste dropped by 22% due to precise energy control.

The non-contact nature of the laser process also reduced tooling wear and maintenance downtime. The system paid for itself within 11 months, driven by energy efficiency and reduced scrap. Long-term reliability has been confirmed after 18 months of 24/7 operation with no source degradation.

Below is a comparison of the old TIG method versus Klear Laser’s fiber laser welding solution:

The shift to laser welding improved weld strength by 40% in peel tests, critical for EV battery safety. With precise control over pulse frequency and beam oscillation, the laser minimized intermetallic compound formation. This real-world deployment underscores how industrial laser welding enhances quality, speed, and sustainability in high-volume manufacturing.

Key Features & Advantages

Klear Laser integrates premium JPT MOPA and Raycus fiber laser sources for unmatched precision. These industrial-grade components deliver stable beam quality and fine-tuned pulse control. Their high peak power ensures deep penetration without thermal distortion, even on sensitive materials.

The advanced wobble welding head dynamically adjusts beam oscillation during operation. This technology minimizes porosity and spatter while enabling consistent weld bead widths. Operators easily customize frequency and amplitude for diverse material thicknesses and geometries.

Combined, these components create a highly efficient welding solution. Minimal heat input preserves substrate integrity. The result is stronger, defect-free welds for aerospace, automotive, and medical manufacturing.

Industrial Applications

A laser beam welder is the first choice on today’s auto body-in-white lines because it delivers up to 6 kW of power through a hair-thin fiber cable, letting robots move at 8 m/min while still achieving 3 mm penetration in zinc-coated steel. The same seam that once took a MIG torch and two post-grind stations is finished in a single pass with no spatter, so OEMs keep the corrosion-coating intact and cut production time per vehicle by 12 %.

Aerospace builders rely on the same Ytterbium sources—JPT or Raycus units running at 1080 nm—to join 0.5 mm titanium skins to stringers with a focused spot under 50 µm. The key is the wobble welding head that oscillates the beam 2 kHz in a controlled Lissajous pattern; it bridges the 0.1 mm fit-up gaps typical of thin aerospace sheet without filler wire and keeps heat input below 0.5 kJ/mm, so post-weld distortion stays inside the 0.05 mm tolerance window.

In the marine sector, shipyards retrofit a 4 kW hand-held laser torch to replace stick welding on 6 mm AH36 deck plates. A 1.2 mm penetration root pass followed by a 2 mm cosmetic cap eliminates back-gouging and reduces total heat by 40 %, which stops the oil-canning that used to require days of fairing compound. The pulsed waveform also ties into battery packs, so work continues below deck without generator fumes.
