Special Headed Bolt YZP tells how to remove the bolt after it is broken?

The bolt is broken, do you know how to take it out? Let's follow the Special Headed Bolt YZP editor to have a simple understanding!
1. First, remove the sludge on the surface of the broken bolt, use the center blaster to kill the center of the section, and then use an electric drill to install a 6-8 mm diameter drill bit. Drill a hole at the center of the section. Pay attention that the hole must be drilled through. After the hole is drilled, remove the small drill bit and replace it with a drill bit with a diameter of 16 mm, and continue to expand the hole of the broken bolt and drill it through.
2. Take a welding rod with a diameter of less than 3.2 mm, and use small and medium current to carry out surfacing welding from the inside to the outside of the drilled hole of the broken bolt. At the beginning of the surfacing welding, take half of the entire length of the bolt. When starting surfacing welding, do not start the arc too long, so as not to burn through the outer wall of the broken bolt. After surfacing welding to the upper end surface of the broken bolt, continue to surfacing a cylinder with a diameter of 14-16 mm and a height of 8-10 mm.

3. After the surfacing is completed, hammer the end face with a hand hammer to make the broken bolt vibrate along its axial direction. Due to the heat generated by the arc before and the subsequent cooling, coupled with the vibration at this time, it will cause looseness between the broken bolt and the thread of the body.
4. Observe the bolt carefully. When you find a trace of rust leaking from the fracture after knocking, you can take the M18 nut sleeve, place it on the surfacing stigma and weld the two together.
5. After welding, use a torx wrench set while it is still hot, and twist the nut back and forth, or tap the end face of the nut with a small hammer while twisting it back and forth, so that the broken bolt can be taken out.
6. After taking out the broken bolts, use a suitable wire hammer to process the threaded buttons in the frame to remove the rust and other debris in the holes. Whether it is small screws for electronic equipment, general screws for furniture and electrical appliances, and even large screws used in engineering, construction, bridges, transportation equipment, airplanes, trams, automobiles, etc., screws occupy a very important position in these fields. .
The above is the Special Headed Bolt YZP editor describing how to take out the bolt after it is broken. I hope you can learn more about it through the introduction of the above editor.
