A fillet weld can be a lap joint, tee joint, or corner joint.
The goal is to get penetration down into the bottom of the joint or at least as close as possible.

TIPS: KEEP A FAIRLY TIGHT ARC AND WATCH TORCH ANGLE
Aim for an arc length that is equal or less than the diameter of your tungsten electrode.Torch angle can be forgiving provided your arc length is tight.
Machine settings vary from brand to brand but No matter what TIG welding machine you use, the settings listed above will get you in the ball park.
