Zirconium Welding

We uses to weld Zirconium in the reactor plants on submarines, but that technology was classified, so I could tell you but I would have to kill you!!

i not sure you can do

thank you very much, it so usefull for me

Welding Processes

The most common process used for zirconium welding is GTAW. Manual GTAW allows all-position welding of any configuration the torch can access. Automated GTAW usually is limited to flat or horizontal positions. Seam welding machines with copper backup bars and continuous hold-down using copper bars are common for straight joints. Tube-to-tubesheet and small pipe butt welds using automatic orbital GTAW equipment also are very common.

PAW often is used for single-pass welds up to about 3/8 in. (9 mm) thick using automated equipment, copper backing bars, and square butt weld preparations. Typically, a GTAW cover pass is used to correct underfill, and the root side may require a cosmetic fusion pass or mechanical removal of excessive drop-through.

A high-current process, such as keyhole GTAW, should be considered for repetitive welding of heavy sections. Electron beam and laser welding also are suitable.

thank you all

Hai

GTAW is the best process for your requirement, but you need to work out the following.

1. Tungsten electrode

2. Filler Wire

3. Gas

4. Polority
