Weld Monitoring

Hello,

I'm from National Automation and Technologies Inc. in Hamilton, Ontario. We are currently working on an application where we have been asked to monitor or to ensure the intergrity of a weld. The application is cold rolled steel being inductively welded at 100'/min. Is there anyway of using eddy current type technology to look for cold/bad or missing welds? If anyone has ever done something like this your input is much appreciated.

My company markets the Technofour range of instruments and mechanics for eddy current testing.

One of their products is the "Flawmark E.C.", specifically designed for testing wires and tubes made from ferro=magnetic materials, and includes inspection of a seam weld in tubes.

This instrument will be eminently suitable for your application, and because it is manufactured in India, will have a very competitive price.

Please contact me with more details of your application.

Our web-site is www.hands-ndt.co.uk and that of Technofour is www.Technofour.com

With my best Regards,

Godfrey Hands

Re: Weld Monitoring
I've done quite a lot with this in the past.

Small defects can be found with a magneticaly biased differential probe, Detecting unwelded sections requires an absolute channel.
Detection of 'cold' welds tends to involve some kind of signal analysis , nowadays computerised. This is the one area which is bit more of a problem.

Unfortunately Zetec, who I work with at the moment, dont have equipment for this market. Companies who do, and who have reasonable support in North America, Include Hocking, Rohmann, Forster, Pruftechnik and MAC

Good luck
Joe
