Laser Welding

High-speed, low-distortion welds with a narrow HAZ — ideal for thin-section assemblies, cosmetic joints and dissimilar materials.

Laser welding delivers a focused, high-energy beam that produces a deep, narrow weld bead with minimal heat input and virtually no distortion — critical for precision assemblies and cosmetic parts. CNC-guided laser heads follow complex seam paths at high speeds. Suitable for thin-section stainless, aluminium, copper and dissimilar metal combinations that are difficult to join by conventional arc processes. In-process monitoring ensures weld consistency without manual intervention.

Frequently Asked Questions

Laser welding is most economical between 0.2 mm and 6 mm. For thicker sections, hybrid laser-MIG or conventional MIG/TIG is more cost-effective.
Yes — laser welding is one of the few processes that can reliably join dissimilar combinations such as stainless to copper or aluminium to steel, particularly in thin sections.
Our laser cells use inline photodiode and plasma sensors to detect weld anomalies in real time. Any deviation triggers an alarm and the part is flagged for inspection.
