Advanced Fiber Laser Welding Technology
Scantech Laser designs and builds industrial-grade laser welding systems that deliver deep penetration keyhole joining, cosmetic surface welding, and high-speed multi-axis robotic processing with minimal thermal distortion.
Industrial laser welding employs a concentrated, high-energy laser beam to fuse metals and specialized thermoplastics with unprecedented precision. By delivering focused energy densities up to 106 W/cm², our fiber laser welders rapidly melt target material while keeping total heat input extremely low.
This narrow thermal focus prevents thermal warping, preserves structural grain boundaries, and yields clean, high-tensile metallurgical bonds without requiring post-process grinding or flux cleanups. Engineered inside our ISO-certified facilities in Navi Mumbai, every system is customized with laser sources, beam-shaping galvo scanners, and motion control tailored to your specific metallographic requirements.
Why Global Manufacturers Upgrade to Laser Welding
Comparative technical trials confirm substantial savings in production cycle times, filler wire consumption, and post-weld refinishing labor.
High Precision & Low HAZ
Sub-millimeter focal spots concentrate heat strictly at the seam, preserving metallurgical grain structure and preventing component distortion.
Superior Joint Integrity
Deep penetration keyhole welding creates dense, hermetically sealed weld seams with zero internal porosity and exceptionally high tensile strength.
Dissimilar Metal Joining
Wobble beam delivery enables reliable welding between copper, aluminum, stainless steel, nickel alloys, and coated metals with contrasting melting points.
Automated High-Speed Yield
Easily retrofitted with 6-axis articulated robots, machine vision alignment, and seam tracking sensors for 24/7 continuous industrial throughput.
Comprehensive Laser Welding Configurations
Four specialized operational modes engineered to match specific material thickness, seam geometry, and cycle time targets.
Keyhole Laser Welding
High peak-power density creates a vapor channel into thick metals. Yields narrow, deep-penetration weld seams with high depth-to-width aspect ratios for structural automotive and powertrain parts.
Conduction Laser Welding
Energy is absorbed smoothly on the material surface and transferred via thermal conduction. Ideal for smooth cosmetic joints, thin foil sealing, and delicate electronic housings.
Galvo & Wobble Laser Welding
Dual-axis galvo optics oscillate the laser spot in programmable circular or figure-8 patterns, bridging joint gaps up to 1.5mm and stabilizing high-reflectivity copper welding.
Robotic & Seam Laser Welding
Continuous high-speed laser seam welding integrated with 6-axis articulated robots, automatic wire feeding, and real-time vision guidance for large 3D structures.

Fiber laser welding concentrates power density up to 10^6 W/cm² into a micro focal spot. This extremely rapid energy delivery creates narrow keyhole or conduction welds at speeds 4x to 10x faster than traditional arc welding, minimizing thermal conduction into adjacent base metals and virtually eliminating structural deformation and post-weld grinding.
Yes. Our systems feature high-power single-mode and multi-mode fiber lasers combined with dynamic dual-axis wobble optical heads and optical back-reflection protection. This enables highly reliable welding of aluminum alloys (6061, 5083), pure copper busbars, and dissimilar metal combinations such as copper-to-aluminum.
Absolutely. We supply both standalone Class 1 laser welding workstations and fully integrated 6-axis robotic welding cells featuring seam tracking sensors, machine vision positioning, inline weld defect monitoring, PLC/MES interface connectivity, and automated clamping fixtures.
Scantech Laser machines are manufactured in ISO 9001:2015 certified facilities and adhere strictly to international Class 1 laser safety standards (IEC 60825-1 / EN 60825-1) with interlocked protective enclosures, optical density-rated safety glass, CE compliance, and comprehensive FAT/SAT protocol documentation.
