Before beginning I do want to say there are not many places that will give you the chance to learn how to TIG weld thin wall stainless steel pipe. I was lucky enough to have Fluor train me and am very thankful for being able to attend their training program! Fluor is the only reason I got to learn this skill!
What I can share is that TIG welding stainless steel pipe is not much harder than carbon steel pipe. There are a few rules to follow and you should be able to pick it up quickly! The rules are as follows:
- Purge your pipe well.
- Everything must be clean.
- Keep your tungsten moving at all times.
- Allow the pipe to cool before the next weld.
Stainless steel pipe must always be purged. The result from a less than perfect purge will cause the root to get contaminated. The slang term used in the field for root contamination or oxidization is "sugar". Sugar is caused from the weld being exposed to oxygen in the atmosphere. The weld joint must be taped off and only untapped when you are ready to weld that part if the pipe.
In general TIG welding requires a very clean weld joint but with stainless steel this is an absolute must! The tungsten must be clean. That means cleaning it after every restart and pass. The weld joint must be filed before every pass except the root pass. Even the bevel needs to be filed on the hot pass and all color changes need to be filed to pure metal at all times. Failure to file all heat affected areas will result in the filler wire not being able to flow into the joint smoothly.
Moving your tungsten quickly is very important when TIG welding stainless steel pipe. The trick to avoid melt through and overheating the pipe is to move quickly. From the moment you strike the arc that tungsten needs to be moving. Don't start and wait for the metal to heat up before moving. Ideally you want to start 3/4 of an inch before the area you will start adding filler wire too. This will allow enough preheat for the filler wire to flow properly. Ideally when the weld is finished it should have a copper color to it. If it is gray or dark in nature you are using too much heat or moving too slow!
When it comes to stainless steel the heat this metal absorbs and holds is unbelievable. Now add thin wall pipe to the picture and you have a radiator that is always ready to overheat! You need to allow the pipe to cool enough that you are able to touch it with your bare hand. TIG welding stainless steel pipe requires a lot of waiting for the pipe to cool. It only takes an extra inch of weld too soon to ruin the weld joint!

How to Take Care of your Welding Helmets
Welding helmets are one of the most important items of protection equipment anyone in the business would need; welding exposes the workers to high intensity light, ultraviolets and infrareds that can cause irrecoverable retinal lesions. Welding helmets come in a variety of seizes and forms, but the most important thing is that they be both secure and comfortable. The best tools to use are the lightweight ones since, too heavy a helmet can tire the neck and the back, particularly since welding implies work in very awkward positions. Lightness is not the only feature of this piece of equipment, welding helmets also require durability.
Considered the best welding helmets available, the items with auto-darkening properties change their color within a fraction of a millisecond, as the electric arc is struck. The detection of the flash is so rapid that you don't even notice the moment when the lens has gone dark; furthermore auto-darkening welding helmets offer protection even when the filter is not activated, this prevents the UV and IR from harming your eyes even in the absence of high intensity light. Regular welding helmets are not more expensive than $40, but the more sophisticated the technology, the higher the prices.
What does improper eye protection lead to? First of all we should say that developing certain work-related health affection is not uncommon at all, and it usually happens within years. The sight-hand coordination is not the same and cataract is often the consequence of faulty welding protection equipment. When choosing welding helmets it is important to be aware of the relationship between light intensity and the color shade of the protection item. The filter shade is the one that regulates the amount of light that reaches the eyes: too dark a filter may prevent the welder from getting work details, whereas too light a shade increases the risk of eye damage.
The filters of the welding helmets are numbered to indicate darkness degree; welders can make the right choice with the help of the standard selector charts that allow matching the filter shade with the type of application you need. At work completion, welding helmets must be cleaned of dust and dirt; there are special solutions designed to preserve the coatings intact. Afterwards, the equipment should be deposited in an area that is not exposed to direct sunlight, dust and moisture since such elements may diminish effectiveness.

How many of you have a "Neighbor from Hell"?
I just can't get over how many things my neighbor does that is not really illegal, but against county code. Just to mention a few noise of the unreasonable level - 6 small kids homeschooled yelling and SCREAMING all day and some nights until way after dark, loose dogs, burning rubbish and tons of smoke very late at night, working on large construction equipment by welding, grinding and pounding all day long (this is a residential area and he knows and he's been told but it doesn't stop), diesel fumes that would kill an elephant, I could go on and on and on...it never stops, something new every day...yes police have been called, yes the neighboorhood association has been notified. Don't know what else to do. We can't move for a couple of reason, and it's not fair we should have to. It's a living nightmare.
WOW That sounds horrible. I only have a little boy down the street that brings saws down here and cuts all the middle branches out of my big evergreen in the back yard, busted up my sidewalk, and found out the combination to my oldest sons bike and kept unlocking it and riding it so I had to buy a new lock. He threw a rock and hit my youngest son in the head and lied to me about it. He is corrupting my children and destroying my RENTED house and I can't wait to move!
