Hi. I'm not a trained welder but have been using Harris Safety-Silv 56 and Stay-Silv white flux to repair and or build several small projects that are made of steel and/or stainless steel. I heat with cheap propane torches.
I have been getting amazing (at least to me) results of strength and even visual appearance.
What are the drawbacks to using these products rather than actual welding? It just seems too easy and am wondering if I'm missing something.
I do understand that breathing flux fumes is bad, especially fluorine.
