Technically it’s called a workpiece clamp and it’s not a ground to earth. You can weld electrode negative or electrode positive depending on machine and process. Placing the clamp too far away from the weld or poor contact may cause crappy welds but it’s not going to melt or arc off your crank. Electronics is a different story.
