TIG Welding Practice on Lap Joints

Today we’re TIG welding some carbon steel lap joints. Roughly .120 thick. That’s three millimeters thick. We’ll talk a little bit about filler metal size, gas lenses, and why the second side usually welds worse than the first side. Let’s get into it. read more

60 ft Metal Rack – Dual Shield Flux Core

Just a few videos ago I talked to JD out back of his new location sitting on a gang box and asked him what kind of work he liked to do. You remember that? What’s your favorite kind of work?

JD: “Favorite kind of work is either big pipe or big mezzanine, just doing the bigger, heavier stuff. It just pays better too.” read more

2 Practical Examples for AC TIG Settings

This is gonna be a really quick video. I’m just trying to add to the conversation from the previous video about AC frequency.

So in the previous video, I got this piece of eight inch tubing, 070 wall, that’s not quite 2 millimeters. Put some lines on it, put it in a positioner. Propped my hand on a stand. And once I got the travel speed kind of figured out, where I keep it all the same, try to get me out of the equation, then I experimented using 50 Hz. That was this right here, how it was penetrating all the way through with no problem. And then I didn’t change anything, and increase the frequency to 250 Hz. No penetration. Got a narrower bead and a higher-pitched sound, but that’s about it. read more

AC Frequency Settings: TIG Welding Aluminum

I’m TIG welding aluminum today, and I’m comparing AC frequency. I’m gonna compare 50 hertz to 250 hertz. I’ve got some aluminum tubing, some eight-inch aluminum tubing, O-70 wall. It’s a bit less, a little bit less than two millimeters thick. I’m gonna set it up on a positioner and I’m gonna compare penetration, same amperage, 50 hertz, 250 hertz. Let’s do it. read more
