Handheld Laser Welding Machine

KRRASS Handheld Laser Welding Machine

Fiber Laser Welding is a welding technology used to create a strong joint between several metal components with fiber laser. Fiber laser produces a beam of high-intensity that is concentrated into one spot. This concentrated heat source enables fine, deep welding with high welding speed. KRRASS handheld fiber laser welding machine is used to weld metal plates and metal tubes.

CNC Control System

High Efficiency

Increased by 2 to 10 times

High Quality

Smooth welding seam, no subsequent grinding needed

Low Cost

Spare at least 2 welders 80% to 90% power saving

Laser welding source selection

Double wobble weld head technology

Double pendulum laser welding head can weld aluminum materials

It can perfectly replace some traditional argon arc welding and electric welding in the welding of thin stainless steel plate, iron plate, aluminum plate and other metal materials;
Light weight, small size, ergonomic design and comfortable grip;
The operation is easy to get started, and the requirements for operators are extremely low;
Beautiful welding seam, fast speed, no welding marks, no discoloration, no need for later polishing;
Strong anti-interference.
