I am new at this so this is a question, on this technique it seems to me that the weld may be too hot and pulling the vertical over a little, if this is so, (which I would like to know), could have a few tacks on backside have prevented this?
------------------------------------------------
Could be, but When i did this comparison, i did not get the pieces perfectly 90 degrees before welding...so there is no way of knowing if the weld pulled it that far.
good observation...I probably should have taken more time and compared distortion also.
tacks might have helped but the shrinkage stresses of cooling weld metal are usually too much for tack welds to stop
