Before or during stainless steel welding operations, it is common to purge with a high purity inert gas. Stainless steel welded pipe tee automatic welder is penetrating, which means that the weld enters the inner diameter of the pipe and forms a structural joint. This type of weld has a smooth surface that can come into contact with any product, is simple to clean, and has no cracks or oxidized layers that could harbor and other contaminants. To enable sanitary design and compliance with standards and regulations, all food contact surfaces should be: smooth, impervious to water, free of cracks, and seams non-porous, non-absorbent, non-contaminating, inert and corrosion-resistant, maintenance-free, and cleanable.
When you create sanitary welds with stainless steel tubing or piping, the welds must be purged with a high-purity inert gas to remove harmful gases released and accumulated during the welding process, which can otherwise cause discoloration, contamination, and oxidation. . The next step in creating a sanitary weld is inspection. Pipeline mirrors are used to verify that the weld is *permeable* and to identify any defects or contamination. Other non-destructive testing methods may also be used. Weld defects include failure to fuse with the base metal, root weld cracking, and failure to weld through. 
Stainless steel welded pipe tee automatic welder weld type: automatic tig weld joint sanitary applications in austenitic stainless steel pipe and piping system welding specifications, austenitic stainless steel pipe and piping, all sanitary welds should be completed using tungsten electrode gas shielded welding process.
Sanitary Stainless Steel Pipe Tee Automatic Welder Automatic TIG welding process, also known as tungsten inert gas welding, is a clean, high-quality welding process that is typically used when precision welding is required. Automatic welding is superior to other processes because it provides greater precision in heat input to the weld area, resulting in a higher quality weld with a smaller heat affected zone. The automatic TIG welding process works by creating an electric arc between a non-consumable tungsten electrode and the metal part to be welded. An inert gas, usually argon, is used to protect the tungsten rod from oxidation or contamination during the process. Automatic TIG welding is suitable for most metals, including stainless steel, and requires little or no finishing work to produce a high quality weld.
