Let's just put this in perspective - the brake pedal pin is 7/16" in diameter where it goes through the pedal arm, which means that it has a cross sectional area of .150 in^2, is in single shear, and it takes the full brunt of braking force.
If the weld made is .0938" (quite small) and goes around the full circumference on both sides of the shaft, then it would have an area of .588 in^2. So, almost 4x the cross-sectional size. That, and the joint is located twice as far out as the pins diameter, so we get double the strength there. Should be, at minimum, 7 or 8x as strong just using a back of the napkin calculation.
*Edit - the pin is actually 7/16" where it goes through the pedal arm*
