Then, on the autobahn, at a speed of 130-160 km/h, the disk will fall apart due to internal stresses from welding, and the car, having turned over several times, will end up broken in a ditch, with the driver and passengers dead! It’s not for nothing that the disc is made completely solid or cast!Something is funny here. An aluminum rim suddenly became steel so that you could weld it to a chunk of steel? Why not just use the steel rim to begin with instead of the charade of claiming you started with a broken alloy?
