TIG Welding for Beginners | GTAW Basic Facts & Tips
Colleagues have been recommending the TIG method, but you haven’t used it before. That’s what led you to seek a guidebook on TIG welding for beginners. You’ve been welding for a little bit of time, and have mastered some of the basics. You would like to get the best TIG welder there is because MIG is sometimes not quite the right option for your project as we explained in our MIG vs TIG
How To Weld 4140 Steel | WELDING ANSWERS
The best option that I can think of is to tack it up, throw it in my oven (which I think is good for a little over 500F) for a while, run a single 7018 bead down each side using 1/8″ rod (I don’t have a machine that’ll run bigger), and bury it in dry sand. After welding I’ll
What is Tungsten Inert Gas (GTAW or TIG) Welding? - TWI
Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is an arc welding process that produces the weld with a non-consumable tungsten electrode. Tungsten inert gas (TIG) welding became an overnight success in the 1940s for joining magnesium and aluminium.

How to Weld Aluminum: The Beginner’s Guide
However, it does utilize a mechanical wire feeding system, which means the welder may have to use a spool gun or push-pull gun to make wire feeding possible. Additionally, in order to coat the risk of aluminum becoming porous, the base material and filler rod must be clean, free of moisture and have excellent shielding gas coverage, typically pure argon content.
In other words, unless you do something to help the bead lay down flat, it will hump up. this is partly due to gravity but is also just a characteristic of short circuit mig welding. I either use an upside down V technique or a series of triangles to make the metal spread

Flux-Cored Arc Welding (FCAW) FCAW is an electric arc welding process designed for carbon steel, stainless steel and low-alloy steels. It uses an electric arc to produce coalescence between a continuous tubular filler metal electrode and the base material, and can be done with or without a shield gas.

This study aims to reduce the diffusible hydrogen content in deposited metal during gas metal arc welding (GMAW) and flux-cored arc welding (FCAW) which induces cold cracking. To achieve this, a novel welding torch with a dual gas nozzle has been developed. This special welding torch decreases the hydrogen source gas evaporated from a welding wire by the suction from the inner gas nozzle. In
