First, the sludge of the sludge of the stainless steel screw break is removed, and the center of the section will be killed, and the drill is used to drill a diameter of 6-8 mm, and the hole is drilled at the center of the section, pay attention to the hole must be drilled. After the hole is drilled, remove the small drill bit and replace the drill bit of 16 mm in diameter and continue to expand the hole of the broken bolt and drilled.
The electrode having a diameter of 3.2 mm or less using a small and medium-sized current in the bobbin of the broken bolt. The bolt is taken away from the bolt. The entire length of the bolt can be taken. The arc is not too long when the surfacing is started. The outer wall of the bolt bolt is burned. The reappearance of the bolt on the upper surface of the bolt is then continued to support a cylinder of 1 diameter of 14-16 mm high.
After welding, hammered with a hammer to hang the outward bolt along its axial direction. Since the heat generated by the previous arc and the subsequent cooling plus the vibration at this time, the thread of the bar bolt and the body is generated. Loose.
Carefully observe that when there is a trace of rust after the tapping, it is possible to take the M18 nut on the staining position and weld both.
After the welding, the hot use of the plum spanning gloves on the nut back and right. It can also be taken back and back to the end face with the small hand hammer. This can be taken out.
After removing the bolt, the wire bucklene in the frame is used to remove rust and other debris in the hole with a suitable smeir.
