First, with reference to Fig. 1 ~ Fig. 4, the manufacture method of the glass bonded body 1 shown in Fig. 5 and Fig. 6 is described.
As shown in Figure 1 and Figure 2, the glass bonded body 1 shown in Fig. 5 has the first glass material 10 and the second glass material 20.Shape and the size of the first and second glass material 10,20 are not particularly limited.First and second glass material 10,20 can be tabular, bent plate shape, bending tabular, cylindrical shape etc. respectively.In the present embodiment, the first glass material 10 cylindrically.Second glass material 20 is in discoideus.
As shown in Figure 3, at the end 20a of the second glass material 20, the end face 10a of the first glass material 10 is abutted with the interarea 20b of the second glass material 20.Specifically, be positioned at the mode comparing the position in the outside by radial direction with the first glass material 10 with abutting part 10b, 20d of the second glass material 20 with the end 20a of the second glass material 20, the end face 10a of the first glass material 10 is abutted with the interarea 20b at the 20a place, end of the second glass material 20.
In the present embodiment, specifically, the diameter of the second glass material 20 is larger than the diameter of the first glass material 10.Configure above-mentioned second glass material 20 and the first glass material 10 in the mode that the second glass material 20 is consistent with the center of the first glass material 10, the end face 10a of the first glass material 10 is abutted with the interarea 20b at the 20a place, end of the second glass material 20.Therefore, the end 20a of the second glass material 20 is positioned at the position as compared to the abutting part 10b that the first glass material 10 abuts the outside by radial direction.
As mentioned above, under the state that the interarea 20b making the end face 10a of the first glass material 10 with the second glass material 20 abuts, from the interarea 20c irradiating laser LB of the upper direction opposite side of the second glass material 20.Specifically, as shown in Figure 4, to position irradiating laser LB in the inner part compared with the outboard end 10b1 of abutting part 10b, 20d.Thus, the end 20a of the second glass material 20 is made to melt thus be welded with the second glass material 20 by the first glass material 10.In the present embodiment, to the second glass material 20 irradiating laser LB, until be arranged in the end 20a of the second glass material 20, Outboard Sections 20e in the outer part melts compared with the part 20d, the 10b that abut with the first glass material 10.Its result is, obtains the glass bonded body 1 shown in Fig. 5.
It should be noted that, be preferably, under the state of the temperature more than the strain point the first and second glass material 10,20 being heated to the first and second glass material 10,20, carry out the first glass material 10 of irradiation based on laser LB and welding of the second glass material 20, be more preferably, weld in the temperature range of strain point+5 DEG C ~ strain point+100 DEG C.By adopting in this way, the first and second glass material 10,20 when welding can be suppressed to damage.
The second glass material 20 that glass bonded body 1 shown in Fig. 5 and Fig. 6 has the first glass material 10, engages with the first glass material 10.Glass bonded body 1 is configured with the container of round-ended cylinder tubulose.The size (θ) of the junction surface 30 place angulation be made up of the first glass material 10 and the second glass material 20 is not particularly limited.The size (θ) of junction surface 30 place angulation such as can be less than 90 °, also can be 90 °, can also be greater than 90 °.
Specifically, in the present embodiment, glass bonded body 1 possesses: the first cylindric glass material 10, to close the mode laser welding of the side end on the length direction of the first glass material 10 in the second glass material 20 of the first glass material 10.
In the present embodiment, due to position irradiating laser LB in the inner part compared with the outboard end 10b1 of abutting part 10b, 20d, therefore, in the second glass material 20, melt from abutting part 20d (10b).Therefore, the Outboard Sections 20e melted after abutting part 20d (10b) fusing draws close to the inside.More particularly, the Outboard Sections 20e after fusing draws close to the inner side at junction surface 30.Therefore, the first glass material 10 is thickening compared with other parts with the junction surface 30 of the second glass material 20, forms protuberance 30a outstanding to the inside.Therefore, it is possible to obtain the glass bonded body 1 of high strength.
From the view point of the glass bonded body 1 obtaining more high strength, be preferably, thicken junction surface 30 further.Therefore, be preferably, to the second glass material 20 irradiating laser, until the Outboard Sections 20e of the second glass material 20 melts.By adopting in this way, when irradiating laser, the Outboard Sections 20e after fusing draws close to the inner side at junction surface 30 further, can thicken junction surface further, thus can obtain the glass bonded body 1 of more high strength.
In addition, as shown in Figure 4, be preferably, irradiating laser LB as follows, namely, when observing from the direction vertical with interarea 20b, 20c of the second glass material 20, the center C1 of the luminous point of irradiation on the interarea 20c of the second glass material 20 of laser LB to be positioned at compared with the center C2 of abutting part 20d (10b) position in the inner part on the thickness direction of the first glass material 10.By adopting in this way, the Outboard Sections 20e after fusing is easily drawn into the inner side to junction surface 30, thus can thicken junction surface 30 further.
In addition, be more preferably, when observing from the direction vertical with interarea 20b, 20c of the second glass material 20, the luminous point of irradiation on the interarea 20c of the second glass material 20 of laser LB to be positioned at compared with the medial end 10b2 of abutting part 10b, 20d position in the inner part on the thickness direction of the first glass material 10.By adopting in this way, the Outboard Sections 20e after fusing is easily drawn into inner side, thus can thicken junction surface 30 further.
It should be noted that, as shown in Figure 6, according to the irradiation position of laser LB, sometimes also can form recess 20c1 on interarea 20c.But the degree of depth of the aspect ratio recess 20c1 of protuberance 30a is high.Therefore, even if when being formed with recess 20c1, the glass bonded body 1 of high strength also can be obtained.
