Work angle: With wire welding, hold the gun at a 10° to 15° angle into the direction you are pushing the weld. With stick welding, maintain a 20° to 30° lead angle in the dragging direction. With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at a 45° angle between the two pieces of metal.

The heat of the weld melts material, causing microscopic voids and inclusions to combine and form significant porosity. But if the weld pool is melted a second time, the porosity can bubble out or vaporize from the weld area. Fortunately, electron beam welding technology can be very tightly controlled from both a location and a depth perspective.

Kiss over the bottom outside and the ends with a cutter after welding and nobody will even know it is welded. Put a copper chill bar in the gap to keep it from collapsing, and you may well find you're done and moving on to the next job before a guy with a slitting saw has even really gotten started on it.
