The welded strap in the last picture is factory.

Both those strut rod holes have a notch worn in the holes. The hole is supposed to be a perfect circle. You probably could weld that notch out and carefully grind it smooth and circular.

Someone drove the car with totally shot suspension. Most likely shot strut bushings. Could put some stress on the LCA stud holes and contributed to the drivers side braking.

The first picture looks like someone has tried to repair a broken stud sleeve in the past. Grind those weld off and re-weld. OR weld a washer around there.
