This is chromoly tubing typical of bicycles.
Probably should not look like the above picture yah!
This is an ugly weld but will hold !
All sexy up here !
And finally some aluminum !!!
Notice the consistent etching zone around the weld on this bicycle frame.
Metallurgy plays a huge part of welding , it may look like a good weld but...
TIG Welding
- According to the Welding Robots website, TIG welding is the primary method used within the aerospace
industry. While TIG is typically more costly, time consuming and difficult, it produces high-quality welds. TIG welding requires the use of both hands and one foot to operate a foot pedal.
Bottom Line
- TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.

I will add photos as I come by them and will eventually add some of my own work here , both good and bad !!!
Happy Welding !!!!
I learned some interesting things about welding in just a short email exchange with Shan. Further, his blog makes some intimidating concepts approachable. Thanks for maintaining this site and sharing your knowledge, Shan!
ReplyDeleteYou second picture labeled "filer rod" I find inaccurate. I have a IGBT tig welder that is able to adjust HZ frequency and pulse. Doing so Im able to use a water cooled torch and pin point a very hot small puddle if need be. Just my 2 cents
ReplyDeleteThese pictures depict transformer type machines as for the most part, they are industry standard.
ReplyDeleteInverter type machines will produce very different welds due to greater tuneability.
The old Miller Aerowave with it's vast array of knobs is the predecessor to the machine I currently use. (Miller Dynasty 200DX)
We are a group of volunteers and opening a new scheme in our community.
