Phased Array weld inspection

PALM

NDT inspections of circumferential butt welds are a complex task. This type of joint is found in various structures including small-diameter tubes in boilers. Experts  inspect these to find defects which could result in the failure of a component, possibly inducing a human or environmental hazard.

The Inspection Robotics PALM Scanner is a compact, lightweight and robust tool that uses ultrasonic phased array technology to reliably, efficiently and safely inspect the weld integrity of small diameter tube racks with clearance as narrow as 12 mm.

fast & easy setup

The set up time for an inspection is less than one minute. The PALM Scanner comes in one piece, ready for inspection. Scanner assembly and adaptation to a specific diameter is not required.

Safety

New or repaired welds are usually inspected by radiography (RT). The technology requires the evacuation of the workers on site, as well as considerable time for developing the RT films.

High Productivity

Inspecting welds by Phased Array means immediate results for the operator. Welder & inspector work back to back during the job. Repair or exchange decisions can be made on the spot.

 

Modules

Inspection Robotics’ Palm Scanners answer today’s challenges to successfully and reliably perform circumferential butt weld inspections. Ultrasonic Phased Array technology provides several benefits in terms of safety, productivity and inspection quality.

PALM circ

Phased Array weld inspection

The PALM Scanner family inspects pipes of diameters from 1.5” up to 3.5”. The tools are adaptable with various wedges and phased array probes to suit any inspection procedures regardless of tube thickness, material or acceptance criteria.

PALM DS

double sided weld inspection

PALM scanners that offer unparalleled ease-of-use experience to operators with superb mechanical design and quality. The ultrasonic PA probes and wedges crafted specifically for this application ensure the outstanding inspection quality. The PALM DS extension allows to inspect welds from both sides simultaneously.

Probes & Accessories
