Are you talking about manual stick welding or mechanized GMAWs welding?

Re: ultrasonic testing of butt weld in cross country pipeline
We have developed an automated x-ray system as an alternative to film x-ray or ultrasonics for cross country pipeline girth weld inspection. The inspected welds can be either manual or automated method. Take a look at the GW-1 at http://cmosxray.com

. You can use whatever RT setup you want for the manual welding depending on the speed of your spreads. Maybe a crawler, but for the GMAW-s you ought to be looking into automated UT. Some of the IF encountered with this process, especially with the heavier wall pipe is difficult and sometimes impossible to detect with RT.

Re: ultrasonic testing of butt weld in cross country pipeline
Whee automated welding processes are used i.e. automated GMAW, ultrasonics has become the preferred method of inspection. High speed UT paint brush scanninng primarily based on zonal discrimination as concieved in Canada is widely used.

There are a number of service companies around the world offering services some of which have already posted responses.

If you want to aquire equipment you can look up people such as RD-Tech Canada and Automated Inspection Systems California.

Systems can be expensive so you need to think carefully. We have worked with several operators wishing to convert to using this technology.
