JD Brewer - Pulse Settings and Silicon Bronze on a ZTfab Cart
JD ordered a cart for his shop that included bottom drawer and foot pedal holder. In this video, we use a torch switch at high amperage for tack welding, then we compare straight welding current to pulse TIG.
And.... we experimented with pulse settings using silicon bronze rod and lay wire techn...
TIg welding box cutter blades can be very good practice because it makes you get used to focusing your eyes on a very small puddle, you have to get used to using a very small filler wire, and you also see how beneficial it is to use aluminum backing on thin metal.
TIG Welding 4140 Handles to Sockets with Hastelloy W
Modifying Wrenches is common practice in certain industries like aviation maintenance. There are tight areas where a conventional wrench wont fit.
Hastelloy W is usually a great choice when you know its steel but cannot determine the exact metal type.
This project was sent to me by a laser cutting company that sells them as weldable kits. It was a good practice project that required a lot of different torch angles. Rotating the torch head as you weld is shown along with plenty of instructive arc shots
200 amps might seem like a lot but with the large heat sink due to the size of the project, 200 amps was actually about right for a lot of it. I used the foot pedal and for some of the welds, I backed off the amps quite a lot but for a few of the welds I was welding a 3/16" (5mm) thick doubler a...
TIG welding cold rolled steel 3"x3" x1/4" using er309L and E70s-6 filler metal.
12 outside joints provides plenty of welds to experiment using different size filler metals and pulse settings too.
There is also a second video of filling in the corners using silicon bronze.
After watching at least 20 videos on making Rocket Stoves, I decided to try my own design. I scrounged up enough scrap materials laying around the shop to make one that works really well. I used A 10 inch piece of 3" stainless tubing
and a short piece of 1-1/4" sq tubing about 5 inches long w...
The difference between TIG brazing and TIG welding is brazing occurs above 840f but below the melting point of the base metal being joined.
Silicon bronze filler metal melts around 1800-1900f and carbon steel melts around 2800f.
Silicon bronze is a useful rod to have in your tig arsenal because i...
The monster coupon is a fairly common test given because it qualifies for a greater range of diameters and thickness. This video shows some techniques for the stick fill and cap and body positioning tips.
