[TheForge] Brooms and Welding Cast

[Washington, Aubrey O.]

Tod,
Explain that a little more.  Why would there be less induced stress with torch welding?  I would have thought there would be more because you have to melt the base metal in a very localized area.  Whereas with brazing I could heat the whole piece up to almost the brazing temp.

Hi Aubry,
If I had my choice of brazing vs torch welding I would torch weld. Less
induced stress, more durable.

        malady?
Prometheus: I planted blind hope in the heart of

Chorus: A mighty boon thou gavest there to man.
Prometheus: Moreover, I conferred the gift of fire
Chorus: And have frail mortals now the flame-
        bright fire.
Prometheus: yes, and shall master many arts
            thereby."
