Welding

Welding HistoryRTech Welding
When I was an apprentice at Dowty we were sent to Stroud College to learn some specialist skills and complete an electronics project. We decided to build a tracking solar panel that followed the sun. For this we needed a framework to support our mocked up panel. So I temporarily joined the metal work class and watched the demonstration of lots of different types of welding. I also learnt how to braze using Oxy-Acetylene. I practiced this on the framework for the tracker.

More recently I attended an evening class at Chelsea College of Art and Design with some other beginner welders where I built a giant flea sculpture using MIG welding.

After doing some research I bought a small DC TIG welder from R-Tech Welding who I also use for welding supplies. The reason for picking this is that it’s has less sparks so is safer for my small workshop and can be used on a wide variety of sizes of steel. I did not need to use the welder in a lot of different places so transporting the argon tank is not an issue. I have used this welder for variety welding projects in my workshop shed which you can see listed below. If you use MIG or TIG then I can definitely recommend getting a large refillable gas canister (in my case argon) as the small disposable canisters will run out quickly and it will become expensive very quickly. I found that even for a quick project such as my Obelisks that required multiple canisters.

TIG Welding thoughts on grinding tungstens

TIG Welding thoughts on grinding tungstens

I’ve been reading a little on preparing the tungstens for TIG welding (GTAW). The tungsten in your TIG welder is a critical component and the correct grinding will affect the ease of use and the quality of your weld. Most

TIG Welding

TIG Welding (Tungsten Inert Gas) or GTAW (Gas Tungsten Arc Welding) uses an electric current to generate an arc between the work and a tungsten electrode. A gas is used to shield the joint from oxidisation. Typically this is the

Following some videos and discussion of the sculptures of Sir Anthony Caro Richard Wilson, I got cracking with MIG welding my flea scuplture.During the week I’d ground down some of the joints so I could re-weld them as double-v butt
