There are several charts in text books and on web sites that depict the penetration profile caused by different grind angles of tungsten electrodes.
I like to see things for myself so I tested 3 very different angles on pieces of 2% lanthanated electrodes ...all 3/32" (2.4mm).
I let the piece cool completely in between beads and kept the arc gap the same for all three beads.
Travel speed as constant too on a welding turntable.
I cut the beads all the same distance from the start point and polished and etched using a stainless steel heat tint removal solution.
