eliminating the blow back of the arc that was happening previously and enabling the welders to produce a perfect root weld.” Huntingdon Fusion Techniques HFT®’s Weld Backing Tape™ comprises ...

The joint around the underbead, however, needs to be protected simultaneously by purging the air that could be in contact with this underbead, known as the root weld, thus protecting the exposed ...

Engineers at the University of Surrey have developed a novel way to see how crucial welded components hold up under the intense heat expected inside a fusion reactor. Their findings reveal ...

though there is a risk of incomplete fusion due to the low arc pressure and the advancement of the weld pool. This is why a root pass could usually only be welded in a vertical up direction using MAG ...

This achieves a faster purge, down to the lowest oxygen levels, which is ideal for larger-diameter pipes where quality welds are required. Zero color welds can be achieved and there is no loss of ...

CARMS, Wales — Huntingdon Fusion Techniques (HFT) unveiled its updated PurgEye® 100. Weld Purging requires the removal of oxygen and it is important that welders know exactly when it is safe to start ...

A demonstration of Argweld® Backing Tape™ followed, which allowed the argon to flow freely, eliminating the blow back of the arc that was happening previously and enabling the welders to produce a ...
