Weld purge monitoring The portable PurgEye ® 200 weld purge monitor is designed to meet the needs of higher welding specifications requiring

oxygen levels down to as low as 10 parts per million (ppm). The handheld PurgEye 200 from Huntingdon Fusion Techniques (HFT) is totally waterproof and dustproof. It has warning icons on the large screen to show low battery and low sensor

gas over the sensor before discharging it to the atmosphere. The lifetime sensor eliminates the need for changing cells every year or so, as is the case with wet cell instruments. Alarm signals can be given by the PurgEye 200 to show when the oxygen level is within or outside the required ppm range. HFT has a range of PurgEye weld purge monitors to measure oxygen levels from atmospheric content (20.94%) down to 1 ppm (accurate to 10 ppm), at which point no discolouration in welds of any kind should occur. By striving for zero-colour welds, companies can eliminate the post-weld cleaning costs of oxidised welds. Huntingdon Fusion Techniques – UK hft@huntingdonfusion.com www.huntingdonfusion.com New products include short inside scarfing tow bars, a hydraulic power pack with pre-selected pressures and return button to accelerate the out- of-cut movement, and an impeder filtration and pressure station with easy handling. Other products include blanks, tools, rolls and wear parts made of tungsten carbide, powder metallurgical alloys or steel.

conditions, and also displays oxygen readings in percentage or in ppm very accurately down to 10 ppm. Luke Keane, distributor support for HFT, said, “Weld purge monitors are an essential instrument to help obtain non-oxidised, zero-colour welds by monitoring the oxygen level when welding metals such as titanium and zirconium where high quality and high strength welds are required. The PurgEye 200 also finds a place with those making important zero-colour joints in stainless, duplex and chrome moly where a metallurgically pristine weld is produced with the help of high quality purging.” The PurgEye 200 contains an internal electro-mechanical pump for automatically drawing samples of purge

Scarfing technology Saar-Hartmetall und Werkzeuge GmbH is dedicated to the techniques of scarfing longitudinally welded tubes.

Its staff have completely revised its range of products and have made important innovations in the design of the tooling as well as in the quality of the carbide inserts concerning geometry and carbide grades. The company’s hydraulic inside scarfers now start from 19mm inside diameter, and mechanical tooling from 14mm ID. Through its partnership with a coating centre, the company can also improve specific scarfing problems.
