IF you are butt welding, you should weld the entire seam.. a small section at a time, then go back after it cools off and weld more.. If you are lap welding over an offset edge or on top of the base metal, tack welds about 1 inch apart will work. Heat build up will ruin the job.. be carefull...

You can also get some strips of Copper. This copper strip can be shaped some and then hold it behind a hole and weld the edges around the hole up. The weld will not stick to the copper plus the copper will wick heat away some. Go slow and dont over heat the panel.

You will want to stitch it as described above, just be sure to move around so not to overheat any one particular area to avoid warping. After an area has cooled go back and add a little more weld. Patience, take your time and it will be fine.
do not get in a hurry

Weld the entire seam if you want it to hold.
Also, if it's in an accessible area, shine light from behind to check for pinholes. Give moisture ANY place where it can get behind the filler and it WILL bubble it up!
