As the world’s leading supplier of high purity welding accessories, Arc-Zone.com is constantly on the lookout for accessories that can help the welder working with reactive metals and/or in industries like food processing and aerospace, produce the best welds possible. If you’re not familiar with these, here’s a rundown of some of what’s available:
Purge Dams
For welding tube and pipe, there are a myriad of accessories that can be used to purge the backside of the weld—so that the weld on the inside of the tube or pipe is just as strong and contaminant free as the outside. Depending on your application, or your personal preference, you can choose from reusable accessories that allow you to create a purge dam for your weld (Purge plugs, Purge baffles, Inflatable purge bladders) or you may need to utilize water soluble solutions such as Purge Film or Purge paper in sheets and rolls, or pre-cut purge paper.
Weld Tape
Aluminum weld backing tape is a good solution for holding your structure in place to facilitate tack welding or to cap off the tubing.
EZ Zone™ weld tape wraps around the weld joint, which is then purged with shield gas. Operators simply peel back a section of tape exposing the joint to begin welding. Shield gas flows out of the exposed area ensuring no atmosphere enters the joint. This engineered aluminum welding tape includes two halogen-free adhesive areas on the outside edges, and an adhesive-free center “Zone”.
Trail Shields and Purge Cups
Another option is the WeldHugger Shield Gas Kit. Wafer thing, these accessories can be shaped for your welding application. And, for the At-Home PRO, there are less expensive options such as the Monster Nozzle Series Flooding Cups.
If you need to make absolutely sure that your weld environment is free of oxygen as well as contaminants–consider a flexible purge chamber.
Oxygen Monitors
To make sure whichever purge system you’re utilizing is doing its job, you can use a monitor to ensure an oxygen free weld zone.
