Laser notching has a many advantages:

• Lower investment costs than conventional (splitting) processes
• Lower operating and maintenance costs
• No tool wear
• Reproducible, i.e. always creates identical notches, which translates into homogenous cracking processes
• Optimum roundness during fine machining thanks to the uniform laser notch which will be specific to the workpiece and material
• Easy to adjust laser notch

Depending on the job specifications, laser notches can be made to meet a wide variety of different requirements. Every type of notch has its own particular advantages:

• Straight laser notch
• Angled laser notch
• Sinus shaped laser notch

Example areas of application of sinus wave-shaped laser notches:

• Joining workpiece components without previously centring them using guide or contact faces
• Assembly of conrods that are subject to pressure from the bearing pillow
• Safely joining forged conrods with critical internal stress
• Particularly suited for fine fractures such as occur in high-tensile forged or sinter-forged cups
