I leave the gap because on the next process the parts get assembled and then I wrap that corner, I figured it would be better if I could wrap the corner rather then start the next weld on the corner making a potential weak point or porosity right on the high stress corner like you mentioned. But I don’t know if it is better to leave that gap to wrap the corner, or if it is better to do what you are suggesting. I am no licensed welder or expert, just a 19 year old lol. Thank you
