Frightening images of how NOT to weld an alloy wheel. Don't get ripped off with unsafe repairs that look like this. This wheel was brought to us and you can clearly see the crack is still there under the 'weld' . Its not been done properly and is no where near as strong as it should be. Call us now and get yours repaired by experts 07510 57 22 23 ☺️
