LAHW Welding System

Combined Laser and Arc Techniques
Laser hybrid arc welding (LAHW) is an advanced welding process that combines laser welding technology with MIG welding technology, overcomes their respective shortcomings, has good welding processability, and can obtain high-quality welding joints.
DIG’s Laser Hybrid welding offers the excellent gap-bridging ability and easy weld-seam preparation, as well as the low heat input, deep penetration and speed of laser welding.

DIG Benefits
Efficiency: Considerable savings in production time and filler material. No need for edge preparations prior to welding. Slag removal is not required.
Exceptional welding quality: LAHW minimizes thermal distortion and reduces common welding defects such as porosity, cracking, and incomplete fusion.
Smooth Finishes: Produces high-quality welds with smooth finishes, requiring less post-weld processing.
Cost-Effective: Reduces waste and rework, lowering overall production costs.
