Correct however you disturb less properties in the material therefor keeping it from turning to martensite and hardening. keeping the heat effected zone smaller, I do know what you are saying with the heat input if it takes longer which is also true. It’s clear you know your welding and are expirenced in the field so you could counteract this with a faster welding speed. However a beginner would not be able to do this. Would be interesting to do the sums on this and put the actual kj/mm heat input in. We will have to look at this in a future video.
@@weldtechsolutions ah yeah, rapid cooling causing changes in the microstructures? I remember quenching stainless once while it was still hot. My tradesman smacked me in the back of the Hand with filler rod lol
Right one is 100 amps. Heat equivalent to time not amperage.
60 amps takes much longer than 100 amps so it increases overall heat input
