Stainless Pipe Welding

xStainless steel pipe welding is gravy work. Has been. Always is going to be.

If it can be done and get it done well, you’re the man and you’ll never starve yourself. However it takes some focus on detail to get it done right.

The primary factor that separates the boys in the boys or must i say, the actual welders in the fishing rod burners may be the readiness to follow along with procedures for welding stainless. Procedures like awaiting the pipe to awesome among passes, maintaining your hot tip from the fishing rod shielded with argon, snipping the end from the tig welding fishing rod if this will get crapped up, keeping the tungsten sharp.

Among the primary procedures I’m speaking about is PURGE. Stainless absolutely needs to be purged with argon gas to avoid sugaring. Sugaring can also be known as granulation but it’s severe oxidation regardless of what you refer to it as.

You cannot even pull off tack welding with no argon purge that shield the rear side or within the pipe. How do we get it done? How can you safeguard the rear affiliate with argon?

Usually to control your emotions with aluminum duct tape. The ends of a stainless-steel pipe are recorded shut and also the whole inside is purged with argon gas. The opening within the pipe joint is recorded to ensure that argon can fill the whole pipe and push out any oxygen. The tape is peeled back sufficient to obtain a tack when the pipe is purge enough.

What’s enough? The only method to tell without a doubt is by using an oxygen analyzer. A bic lighter won’t have the desired effect. Even 2% oxygen content will fly out a bic lighter. And A Pair OfPercent oxygen can lead to a black root pass.

There are several other lower and dirty ways to determine the purge but an oxygen analyzer may be the sure way.

Listed here are a couple of tips that may help you obtain a good purge around the stainless pipe you weld.

Make certain there’s no water within the pipe…not really a drop. A single drop water will throw a monkey wrench inside your purging until it evaporates. Remember what’s in water? Hydrogen and oxygen.

Poke a vent hole within the uppermost place you’ll find. Consider argon as though it had been water. Since it is heavier than air, it’ll fill any space like water, displacing the environment because it fills every nook and cranny.

More purge gas flow isn’t necessarily better. A higher and turbulent flow of argon won’t always purge a pipe faster than the usual lower flow rate. Along with a diffuser around the finish from the finish of the argon hose usually enables you to employ a greater flow rate. A homemade diffuser can be created with a few stainless made of woll , some perforated stainless sheet, and a little bit of sheet metal.

When you verify a great purge, you are prepared to tack. Peel the tape back sufficient to tack and let awesome a little and re tape. Then tack again 180 levels apart. Continue until all tacks have established yourself.
