It makes me wonder if it is really necessary to back purge or use the flux.Typical weld in stainless steel made without backing gasWith a gas flow of 50 ft3/min, purge time can range from 30 seconds per foot of pipe for 3-inch pipe and smaller to 90 minutes per foot of 48-inch pipe. The inside surface of a completed weld on properly purged stainless-steel pipe will be smooth, even, and uniform.
May 23, 2019 · Welding stainless steel tubes and pipes typically requires back purging with argon gas when using traditional processes, such as gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW). But the cost of the gas and the setup time for the purging process can be significant, especially as the pipe diameters and lengths increase.What is the purpose of the back purge gas for stainless polishing purge welding stainless pipeJan 02, 2014 · When you are welding stainless steel pipe for the food service,industrial or automotive industries back purging is done to prevent the formation of oxides inside of the pipe, which are caused by the presence of oxygen. Alloys like that of stainless steel are prone to formation of oxides if not shielded from oxygen that is present in the atmosphere.Why Passivate Stainless Steel and What Happens If You ated with lack of a suitable welding purge go away, i.e. severe weld discoloration or sugared welds. Cutting, grinding and mechanical polishing also alters the stainless steel surface and can affect the passive surface. It is very important to use tools dedicated for use with stainless steel when performing these opera-tions.
