Have you ever been to Fabtech?
Its North Americas largest welding and fabrication show.

I am heading out the morning after I am writing this for 3 days of “total immersion” into the world of welding a fabrication…all under one roof.

Welding Distortion Tips for keeping stuff straight

Welding Distortion is a complicated subject.

But one thing is certain…
understanding that weld metal shrinks as it cools is fundamental to understanding ways to prevent distortion.
this video addresses welding stainless steel square tubing and shows a technique for using weld sequence and direction of travel to keep things straight.

309 Tig rod for Welding Stainless to Carbon to A572 Steel

309 Tig rods are designed for welding stainless steels to carbon steels…but they are a good rod to have in your shop because 309 is a very versatile rod…good for welding pretty much any steel to any other steel in a pinch.
not necessarily the absolute best all around choice…and it shouldn’t be used indiscriminately…but 309 will usually get the job done.

TIG Welding Rod Rack, Speed Tacking, Chill Blocks, and a cool homemade tool

Speed tacking involves setting amperage to 30-50 percent higher than normal welding amperage. Then using a torch switch or foot pedal, use very quick blasts of half a second or less to fusion tack weld.
this makes for very quick tack welding that is clean and free from oxidation.

Aluminum Chill blocks are handy for pulling heat out of sheet metal parts. So worth the effort.

A home made tool can be easily made from a cheap screwdriver and some silicon bronze tig rod.

For limiting heat input on thin stainless sheet metal, try these settings…

1 to 1.5 pulses per second
20% pulse time
20% background current

TIG Welding Stainless using both Walking the Cup and Freehand techniques

Walking the cup is a great way to tig weld pipe and other round stuff. But sometimes, there is other stuff in the way and its just not practical.

That’s when you have to prop your pinky or some other part of you hand against the part.
And then things start to warm up.

It sure is a lot easier to make a good weld when your fingers are not roasting.

And a Tig Finger sure does help.

What other people are saying about the Tig Finger

” If you do a lot of TIG welding you know that sometimes finding a good place to steady your torch hand is the hardest part of welding, many times dragging a finger is the only option, but that goes out the window when a part is hot, or you have to drag over what you have just welded, putting thick gloves on helps with the heat, but removes all dexterity and torch control. Not to mention having the leather fingers of your gloves go hard from the heat only to never be normal again.

Well this is your solution, slip this bad boy over the preferred finger and drag away, being made of woven glass, this thing resists heat like Ellen Degeneres resists …well, you know. Never again will you have to burn your finger to get those last few beads laid down.”

S. Stenton

“This product is the bomb…. full stop. Works for all types of welding. Never light up without one. Use it as a prop on your finger or just to rest the palm of your hand and scoot along. Can also double as a clamp pad so you don’t scratch up something you don’t want to. Couldn’t be happier with this.”

Jim Webb

“Very Very Very useful product. Allows more time to concentrate on the weld rather waiting to see how heat your hand can take. I purchased several it was worth every low penny. 10 thumbs up.”

Donald C. Cartier

“Got this at the same time as the Mag-Tab , Tried to mack one of my own , but one works so much better . Thanks
This too I had seeing on Tips & Tricks Welding.”
