Ahoy Brian , three things come to my mind about welding long joints.

One is trying to prevent ripples caused by heat distortion, maybe also called puckering, on long linear welds.

Two, is that the welding heat causes a loss of temper near the weld.

and Three, is later corrosion that seems to start under paint around previously welded areas.

Please DO let us all know, how you decide to go about it .

Enquireing minds want to know.
