question about TIG fusion welding without filler? Answered
Does fusion welding of mild steel with either acetylene or TIG result in the same metal structure; is all melting the same ?
Here is a rambling explanation of why I am asking.
I wanted to start acetylene welding again but have found that the gas prices here in the UK are even worse than I Imagined.
So, I thought to buy a TIG welder : I will be mostly welding 1.5mm mild steel sheet.
I used to enjoy fusion welding with acetylene and hardly ever used filler; does fusion with a TIG welder result in the same molecular/chemical structure as acetylene ?
The reason I ask is that, I looked at hundreds of online opinions about TIG fusion welding of mild steel and generally they all said not to do it as it will cause the surrounding metal to be brittle; but they were proper welders doing proper structural things; I am only doing scultpures and all of of my stuff from 20 years ago is still holding . . . so if TIG melting is the same then I will go for it,
