Eliminate Porosity During Welding with a Dew Point Sensor

The presence of moisture on the joint surface can create porosity in the weld metal. It is therefore important that the dew point is monitored so that welders are made aware when moisture is likely to be present.

Innovators in Weld Purging Huntingdon Fusion Techniques HFT® have recently developed a Dew Point Sensor, an important predication instrument of when water will form on metal surfaces in the welding environment.

Ron Sewell, Chairman for HFT® said: “Under arc conditions, water is broken down into hydrogen and oxygen in atomic form which, when present in weld metal, cause porosity and are known to create cracking in the weld joint. Water can form as moisture on metal surfaces while welding, so it is crucial to be able to measure ‘Dew Point” while welding lengthy critical joints as conditions can change during the welding process.”

“The PurgEye® Dew Point Sensor accessory has been designed to integrate with most of the Argweld® Weld Purge Monitors® via the PurgeNet™ lead that is supplied with them, thereby giving values and water present on the same screen. In this way, the user is not forced into the purchase of an expensive, separate Dew Point Monitor that will give its reading elsewhere.”

The Dew Point Sensor is designed to fit any of the Argweld® Weld Purge Monitors® that read down to 1ppm, which includes the PurgEye® 200, PurgEye® Desk, PurgEye® 600, PurgEye® 1000 and the PurgEye® Site.

Data is displayed on the OLED screen of the Weld Purge Monitor® in split format, so both oxygen (02) and moisture (H20) content are shown as ppm value.

Huntingdon Fusion Techniques HFT® are Weld Purging Innovators, Designers and Manufacturers with offices located globally.

Weld purging is the act of removing, from the vicinity of the joint, oxygen, water vapour and any other gases or vapours that might be harmful to a welding joint. Such gases may combine with the metal to form undesirable compounds that may reduce corrosion resistance or may be instrumental in creating cracks or other structural defects in metals.
