The ROTIX - Chain Weld Scanner kit is designed to provide encoded position of probes circumferentially around piping for weld inspection on ferrous or non-ferrous inspection surfaces.

It is completely configurable for phased array, TOFD and conventional UT with single or multiple probes. Since this package includes a set of 8 magnetic wheels, this scanner can also perform inspection without the chain on ferrous materials like a standard magnetic scanner.


  • Using two link lengths and an adjustable buckle, any size of pipe can be inspected from 152.4mm - 965.2mm (6in - 38in) diameter. Links are designed with quick releases to easily be added or removed.
  • A double wheel chain is used to straddle the weld. This allows the scanner frame to be centered on the weld to reduce wandering and reduce the width of the scanner.
  • An integrated latch allows easy probe centre spacing adjustment and scanner installation. Due to its modular design most major types of phased array wedges can be accommodated.
  • All wheels are coated with urethane to reduce the effects of foreign debris obstructing the rolling of the scanner. Urethane also eliminates the sideways sliding of the scanner in a required position.
  • A brake is provided to lock the location of the scanner in a required position.
  • The encoder output is fully compatible with all standard instruments.
  • The scanner is sealed using O-ring gaskets and seals to protect against the penetration of contaminants into the unit.
