Make sure you get a smooth fillet. 用合适的工具把胶紧贴到恰当的位置，保证得到的是平滑的胶边。 (7) Apply the sealant again to get a full body fillet. 再做一遍以确保胶量充分。 Note: A second application of the sealant is necessary only for integral fuel tanks. You can cut the nozzle end to give the full body seal some contour. 在油箱整体做胶时，重复一遍的做胶过程是非常必要的，也可以将喷嘴的末端割大，从而保证密封胶量的充足，得到比较理想的轮廓。 (8) Use the fairing tool to get the last shape of the fillet. 用胶棒将胶带的形状整理好。 * 结构分部钣金车间培训小组 * 六.密封胶的使用 (9) Push the tool against the sealant and move the tool parallel to the bead. 用胶棒沿着胶带的平行的方向移动一遍，以赶出残存的气泡。 (10) Make sure the seal is smooth. Make sure there are no air bubbles in the seal. 保证所得的胶带是平滑的。并且其中没有气泡存在。 (11) Make sure the bead has the shape of a faired fillet, after the work is completed. 在做胶工作完成后，再修整一下胶带的形状。 * 结构分部钣金车间培训小组 * 六.密封胶的使用 Figure 5 (1/4) * 结构分部钣金车间培训小组 * 六.密封胶的使用 Figure 5 (2/4) * 结构分部钣金车间培训小组 * 六.密封胶的使用 Figure 5 (3/4) * 结构分部钣金车间培训小组 * 六.密封胶的使用 Figure 5 (4/4) 做胶边 * 结构分部钣金车间培训小组 * 六.密封胶的使用 6.3 INJECTION SEALING A. When the seal must be continuous or block a passage or hole, the holes and joggles must be fully filled with sealant, as shown in Figure 6. 孔和下陷处填胶时要保证填胶充分。 B. When an opening is to be closed to hold up a fillet seal, it is not necessary to inject sealant to the full depth of the opening. 当需要做胶密封一个开口区域时，不是必须把胶注满开口的整个深度。 C. When a seal is
