Jointing Solutions

Jointing solutions for LiquidCore

Infrared fusion (IR)

IR fusion machines are characterized by contact-free melting of the components to be fused. This eliminates the possibility of contamination or the pipe faces sticking to the heater. Due to the minimal defined welding bead, there is a good flow in the fusion zone.

Weld Bead Inspection (WBI)

The WBI Tool uses advanced photosensory technology to digitally scan and analyze weld beads with high precision. It provides fast, non-destructive inspection of each joint, detecting optical irregularities and verifying weld quality in real time. This ensures consistent, high integrity connections and supports full traceability across the welding process.
