Tig Welding Stainless Steel - Tig Welding Video - stainless steel sailboat parts

Tig welding stainless steel. That's what the cat in this welding video is doing...and he is good at it. I believe he is welding some stainless steel sailboat parts.

But what can we learn from watching this video?

A few things I notice are:

1. He extends his tungsten electrode farther than normal so that he can get into the tight places without bumping the cup.

2. He uses a gas lens collet body and setup that allows him to extend the electrode and still maintain good gas coverage.

3. He doesn't fart around. He lights up, gets moving and moves the torch about 1/8" every second. You can watch and count if you want...thousand one...thousand two. I got to 10 when he was done with the first bead on this welding video...and the weld was roughly 1 and 1/4" long or 10/8".

It is important on stainless steel not to hang around in one place too long. Heat builds up and its hard to outrun it.

If the welder were to accidentally penetrate all the way thru, the back side would sugar or oxidize and he would probably have to grind it out so that it would still fit over whatever goes inside. He is not back purging and he probably does not need to.

I am guessing that he has welded hundreds of these parts and knows that he is not going to penetrate all the way thru.

I like to weld with this same technique...feed rod...move torch ahead 1/8" and pause...feed rod...repeat.

It gives you uniformity, lets you get in a rhythm, and covers more distance than you do with really tightly spaced ripples.

At least it works for me. You may have another technique that works for you.
