Brazing copper and copper alloys When to use it and how to do it
It is important to be able to identify when brazing is suitable for joining copper or copper alloys, how it is applied, and which filler metals to use. Four processes to consider when joining copper and copper alloys are mechanical couplings, welding, soldering, and brazing. Brazing is suitable for small parts and when high joint…

Money Saving Method of Torch Work on Steel Members
The use of the oxyacetylene flame to do and assist in doing many difficult and some apparently impossible tasks in steelwork is often underestimated. There are a large number of jobs that beginners as well as older welders “pass up”, because they have not become thoroughly acquainted with the possibilities presented by the use of…

Stick Welding Vertical Up with an E7018
Vertical stick welding is one of the positions that has a learning curve that can be really frustrating. Hey, I have been there and know first-hand! However, once you get past vertical welding all you have left is overhead for the structural welding positions. Welding vertical up is not really that hard to do. So here are the…

Circoolator for Tig Welder
I own a Hobart 300Amp DC TIG welder, model 110 Cybertig. This is a very robust machine, it came fully equiped. My problem was that it uses liquid cooled torches. Where it is in my shop would have been a plumbing nightmare if I chose to use “city water”. Air cooled torches are cost prohibitive…
