Back purging stainless steel

Stainless steel is the preferred material in many applications because of its resistance to corrosion.

When preparing to weld a stainless steel pipe, purging is an important step to ensure that the weld is successful and that it remains intact for the long term.

While our demonstration involves a vehicle exhaust tube, purging stainless steel is important when welding pipe for food storage and other applications where impurities must be avoided. For example, failure to purge a pipe that transports food or beverage materials could lead to particles becoming trapped in hard-to-clean grooves, resulting in contamination.

On the outside, a weld on purged and non-purged stainless steel pipe looks identical. On the inside, however, is where the important difference occurs.

A purged weld is flat and tied in on the inside where the weld metal comes together. There are no valleys that could potentially threaten the integrity of the weld. Both portions of the tube look exactly alike.
Please Help.
Thanks !

I didn't find the right solution from the internet.

Joe, what was the question?

Are you going to use a flux capacitor to perform the welds? How many electrons will you use to get the correct cake layer depth?

I'd love to help you on this.
