Common Sense Of Screw Application

To begin, the sludge on the surface of the broken screw head needs to be cleared. Use a central gun to eliminate any remnants in the center section. Next, employ an electric drill fitted with a 6-8 mm drill bit to create a hole at the center of the section. It is crucial to ensure that the hole is drilled all the way through. Once the hole is complete, exchange the smaller drill bit for a 16 mm one, and proceed to expand and fully drill through the broken bolt's hole.

To repair a broken bolt, begin by using a welding rod with a diameter smaller than 3.2 mm. Employ a medium and small current for surfacing welding, starting from the inside of the bolt hole and working your way outward. Initially, focus on surfacing welding half of the total length of the broken bolt. Ensure that the arc length is not excessive to prevent burning through the outer wall of the bolt. Gradually surface weld up to the upper end face of the broken bolt, and then continue to create a cylinder shape with a diameter ranging from 14-16 mm and a height of 8-10 mm. This will effectively repair the broken bolt.

Here is a rephrased version of the provided content:

After completing the surfacing process, use a hammer to strike the end of the broken bolt in order to induce vibrations along its axial direction. This combination of heat generated by the previous arc, followed by cooling and the applied vibrations, will cause the broken bolt to loosen within the threaded body.

To fix the issue of rust leakage from the fracture after knocking, it is important to closely observe the situation. As soon as you detect the issue, grab an M18 nut and connect it to the surfacing column head by welding the two together. This will help to prevent any further leaks and ensure that the equipment remains in good working condition. So, it is essential to take quick and prompt action to avoid any further damage.

One effective method for removing a broken bolt after welding is to first cover the hot nut with a torx wrench. Then, apply a twisting motion back and forth while maintaining pressure on the nut. Alternatively, you can tap the end face of the nut with a small hand hammer while simultaneously twisting it. This technique helps loosen the broken bolt, making it easier to extract.

Once you have successfully removed the broken bolt from the frame, the next task is to clean up the thread in the hole. To do this, you need to use a tap that is suitable for the size of the thread. This will help to remove any rust or debris that may have accumulated over time. By properly processing the thread, you can ensure that the new bolt will fit snugly and securely into the frame. So take the time to clean up the thread to ensure a smooth repair process.
