Ask the manager at an accredited test lab for specific recommendations. I was not aware that there was an "approved type" of thermocouple welder. In any case, have always made my own welders, because I have never had consistent results with something off the shelf. They are very easy to make, and you get exactly what you want for a given type of thermocouple wire and technique.
I recently squashed any requirement to weld in an Argon envelope when an agency engineer was not able to provide 'better' or more consistent data using thermocouples welded with a $6k USD shiny, full of dials, indicators, and lights, welding machine. Although I do whisper some of the (Klingon) R'uustai ritual while welding thermocouples... luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Bolintineanu, Constantin Sent: Friday, July 18, 2008 12:04 PM To: [email protected] Subject: THERMOCOUPLE WELDER Dear Colleagues, I would like to kindly ask you in regard to the THERMOCOUPLES WELDERS that you are using. Information regarding the suppliers, and best performances and reliability, with not to many headaches are very much appreciated. I must admit that what we found is not an approved type... I would prefer to understand which is the best solution without using too many consumables. Please accept in advance my many thanks for your replies.
