Discover the Stainless Steel Pipe Welding
Stainless pipe welding is gravy work. Has been. Always will probably be.
If you're able to get it done and do it well, you're man and you will probably never go hungry. But it takes some care about detail to get it done right.
The biggest thing that separates the boys in the boys or should I say, the real welders from the rod burners may be the willingness to adhere to procedures for welding stainless-steel. Procedures like awaiting the pipe to chill between passes, maintaining your hot tip of the rod shielded with argon, snipping the end from the tig welding rod if this gets crapped up, maintaining your tungsten sharp.
One of many procedures I am talking about is PURGE. Metal absolutely must be purged with argon gas in order to avoid sugaring. Sugaring can be called granulation but it's severe oxidation it doesn't matter what you call it.
You cant even make do with tack welding lacking an argon purge that shield the back side or inside of the pipe. How do you take action? How do you protect the rear affiliate with argon?
Usually it is finished with aluminum duct tape. The ends of an stainless steel pipe are taped shut along with the whole inside is purged with argon gas. Even opening in the pipe joint is taped to ensure argon can fill the entire pipe and push out any oxygen. The tape is peeled back adequate to obtain a tack once the pipe is purge enough.
What's enough? The only method to tell for certain has been an oxygen analyzer. A bic lighter will not likely do the trick. Even 2% oxygen content will fly out a bic lighter. And 2% oxygen will lead to a black root pass.
There are many other down and dirty methods to confirm the purge but an oxygen analyzer could be the sure way.
Here are a couple tips that will help you get a good purge for the metal pipe you weld.
Make sure there is absolutely no water in the pipe...not really a drop. A single drop water will throw a monkey wrench with your purging until it evaporates. Remember what exactly is in water? Hydrogen and oxygen.
Poke a vent hole within the uppermost place you can discover. Imagine argon like it turned out water. Because it is heavier than air, it will refill any space like water, displacing the air since it fills every nook and cranny.
More purge gas flow isn't necessarily better. A top and turbulent flow of argon won't necessarily purge a pipe quicker when compared to a lower flow rate. As well as a diffuser around the end from the end of one's argon hose usually allows you to use a higher flow rate. A homemade diffuser can be created with a few stainless wool , some perforated stainless sheet, along with a bit of sheet metal.
Once you verify a good purge, you're to tack. Peel the tape back sufficient to tack and let cool a little and re tape. Then tack again 180 degrees apart. Continue until all tacks are in place.
