Awl--
In my shaft-repairing contortions, the above question has arisen amongst brazing, tigging, and stick. Also sumpn I've wondered about for a while.
I maintain that brazing involves the most heat, cuz you gotta get the base metal perty red (at least I do!), which is difficult to localize w/ O/A--esp. going around a shaft.
TIGing the next, cuz of the heat involved in puddling. Proly O/A welding is about the same as tigging, mebbe a little more?
Finally, stick welding the least, mainly cuz it's so fast. Some have said higher amps will ultimately deposit more metal with less heat.
Are these assessments correct? Partially correct? Appreciate all opinions.
