Mmmmm, my preference is to cut about 10 mm below the crease..... then fold the crease back inside the door. The new piece also gets a 10mm inward lip.
I then clamp, the 2 lips together.
Fully weld the inside edges of the lips, and only tack weld the outside, about every 25mm. Then filler finishes the crease shape between the tacks.
