4000W Fiber Laser Welding System for Thick Metal

The 4000W configuration is optimized for heavy-gauge materials in the 4mm to 8mm range. Carbon steel achieves full penetration up to 8mm in a single pass, stainless steel up to 8mm, and aluminum up to approximately 6mm. For materials thinner than 4mm, lower power configurations such as 1500W or 3000W may provide more cost-effective operation.

The key difference is single-pass capability. Where arc welding often requires multiple passes with inter-pass cleaning for thick sections, the 4000W fiber laser can achieve full penetration in one pass on materials up to 8mm. This translates to significantly faster cycle times, reduced filler material consumption, and a narrower heat-affected zone that minimizes distortion on large structural parts.

The system includes an external chiller sized for sustained 4000W operation. High-power laser welding generates substantial thermal load, and the standalone chiller ensures the laser source remains at optimal temperature throughout extended production runs-a critical factor for maintaining consistent weld quality.

The 4000W system requires a 380V three-phase power supply. This should be confirmed with your facility before installation. The system is configured to match your local power specifications.

Yes. Carbon steel up to 8mm and stainless steel up to 8mm can be welded in a single pass. Parameter switching is straightforward through the HMI control system, allowing operators to transition between materials with minimal setup time.
