Fast, Precise Dead-End Welding Device

Executive summary

The Technology The welding of tubing presents specific challenges, particularly in dead-end configurations. In order to meet welding standards, typical tubal welding requires an internal gas flow-through purge with a restrictor on the end of the purge component. The restrictor controls the internal pressure to prevent the weld from falling in or blowing out. When confronted with a tubes closed end (i.e., a dead-end configuration), however, the gas purge has no exit. The increase in pressure within the component produces a faulty weld. Using conventional techniques, the only way to get an acceptable weld in a dead-end configuration is to do numerous practice welds before welding the actual component. .By controlling the internal pressure of the gas purge during welding, this new technology produces consistently reliable and high quality welds with minimal setup time. The unique device ...
