Welding stainless steel pipe purging ~ Higher Thickness SS plates and Tubes. Put purge plugs in pipe. Prepare the pipe ends for welding. Seal the inside of the area to be welded with caps or dams.
Stainless Steel pipe needs a good purge on inside of the root pass in order to keep it from getting crapped up. In these areas the welding of piping. During the purging stainless steel pipe welding process the weld seam is subjected to the heat and the air that leads to the oxidation of the processes. Welding stainless steel tube and pipe traditionally requires a back purge of argon.
Pipe welders called it sugaring and the technical term is oxidation or granulation. The back purge on stainless steel was an especially time-consuming process typically requiring 20 to 30 minutes depending on the pipe size to set up the argon shielding gas and tape the pipe ends for purging. There are six basic steps to purging a TIG weld. Why is Back Purging Necessary in TIG Welding.
Stainless steels and alloys with titanium nickel and zirconium when heated to high levels react to water grease and gases floating free in the environment among other things. It is vital when welding metals such as stainless steel zirconium and titanium that the welding zone is purged of oxygen to a level as low as 100 parts per million ppm or even 10 ppm to ensure oxide free zero colour welds are achieved. Higher Thickness SS plates and Tubes. Ad No Min Order Quantity.
In non-critical applications where cost is a driving factor nitrogen can also be used as a back purge but it may lead to the formation of some nitride compounds in the weld. Tack them together. A back purge removes contaminants and provides backing but it also adds significant time and money. With a gas flow of 50 ft3min 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.
Purging the weld is the best way to protect the inside of pipes from oxidation. This reaction causes the filler used in the weld. Look at your dime of a weld. Introduction Austenitic stainless steel welding is widely performed in the fabrication of various components for the chem ical pharmaceutical nuclear food processing and other industries.
Ad Find China Manufacturers Of Welding Wire. Chrome steels must also be purged correctly during their heat treatment cycles before and after welding as well as during the weld purging process. If youre welding stainless steel pipe with a traditional process like TIG or stick it likely requires a back purge with argon gas. When GTAW process alone or a combination of GTAW and SMAW processes is recommended for the production of a particular joint the purging shall be maintained during the root pass and for the first filling pass to minimize oxidation on the inner side of the pipe unless otherwise specified in Welding Specification Chart.
Purging in pipe welding without any adverse effects on the properties of the unstabilized austenitic stainless steels. Specialist in Stainless Steel Pipes and Tubes in all the Grades. Ad Find China Manufacturers Of Welding Wire. The inside surface of a completed weld on properly purged stainless-steel pipe will be smooth even and uniform.
Solar-flux is a powder that is mixed with methanol to form a cream like paste which is then painted onto the inside of the pipeplate. Purge Welding Stainless Steel. I take it your talking about TIG welded root runs. 26WELDING DESIGN FABRICATIONMAY 95.
Either way its ugly stuff. For welding stainless steel pipe Dixie Mechanical followed the traditional process of using a TIG root pass with an argon back purge followed by flux-cored fill and cap passes. Fill pipe with argon. Specialist in Stainless Steel Pipes and Tubes in all the Grades.
Fit pipe together. Oxidation must be eliminated by using different pipe purging equipmentThe quality of the exotic corrosion-resistant material welding is dependent on the correct purging methods to minimize or eliminate oxidation.
