Hybrid Laser Arc Welding
Referred to as Laser-Augmented or GMAW-Augmented, or HLAW (Hybrid-Laser Arc Welding), this welding technology has many benefits to offer over traditional welding methods.
AT&F’s Hybrid Laser Arc Welding (HLAW) system combines a High Powered Laser with the GMAW Welding process in a 20 ft x 60 ft (6.1 m x 18.2 m) working envelope. The combination of the laser weld and electrical arc process happen simultaneously acting within the same weld pool.
Weld Characteristics
- Smooth surface contours
- Small heat affected zone
- Fine grain structures
- Low base metal dilution
- Very high weld toughness
Process Characteristics
- High Productivity based on higher welding travel speeds
- Low Consumable Costs
- Improved Tolerance of Gaps, Edge Quality, Contaminant
- Automated Process
HLAW vs Traditional Welding
- Deeper penetration replacing multiple passes with one
- Lower Heat Input
- Low Distortion/Shrinkage
- Much lower residual stress
- High Weld Toughness and Strength
- Higher Productivity
- Eliminates the need for bevels in certain applications
- Reduces filler metal consumption
