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
