グラインダーなどによｌ■・１のように切削除去する。First, as shown in Fig. 31, a tapered drill 9 is inserted into the metal material 5.
The internal lack of i! 12, the base 2.2 is magnetized and attracted to the surface of the metal material 30. After that, the driver #10 is driven to turn the lever 9tIi1, and the driving body 6 presses the door 9 against the metal material 5, and then!
A tapered repair hole 15 penetrating the metal material 5 in the front and back directions is provided as in Ibm. After cutting out the internal defect 12 of the metal material 3 in this way, return 9 to its original position, stop the cycle, and replace it with rad 8 as shown in Figure 56. Attach the FEI 11 head 14 to the rotating main shaft 7, and then attach the tapered ring-shaped S material ``15'', which is slightly larger than the repair hole 3, to the pressure welding head 14. Applying a rotational force to the drive body 6 and inserting the cypress-like member 15 into the repair hole 13, these tapers m are frictionally welded together as shown in Fig. 54.After this friction welding, EEII
The head 14 is detached from the frame-shaped member 15 and returned to its original position, then the base 2.21 is demagnetized and the metal material 3 is also removed), and finally the plug-shaped member 15 is removed as shown in Fig. 3a.
The remaining members 16 and 16' at both ends protruding from the repair hole 13 are cut and removed using a grinder or the like as shown in 1.1.

取外しも非常に楽であ勤、非常に能率的である。In the internal defect repair device described above, the cutting head 8 and the pressure welding head 14 are added to the same rotating main shaft 7, and each unit has a function of 1. :
, attached. 2J A, Gold, Material-〇 Formation of repair hole 16,
As a result of friction welding of the plug-like member 15 into the repair hole 13 using the same rotating main shaft 7, there is no need to align the plug-like member 15 after forming the repair hole 15. The plug-like member 15 can be appropriately pressed into the repair hole 1s, and highly reliable repair can be performed. In addition, since the frame 1 can be fixed to the metal material 3 by the electromagnetic force of the base 2, it is very easy to remove it from the metal material 5. Very efficient.
一方、上述したように摩擦圧接には栓状部材１５０回転

たがって補修部辷熱ひずみを生じることがない。On the other hand, as mentioned above, friction welding requires 150 rotations and pressing of the plug-shaped member! However, the control can be easily performed according to preset values. In addition, friction welding is a solid phase welding method that uses paper heat input.
The thermal influence on #l1il due to this is extremely small, and therefore no distortion due to heat is caused in the repaired area.

が最適である。In addition, countermeasures should be taken when it is found that in a tank that stores fuel such as flammable gas, there is an internal defect 1!12 (II!5all) as described above in the metal material 3 that is an integral part of the tank. So, next is lI! The method described below is the best.
