ために十分な強度が得られない。The sandwich steel plate has the following characteristics: As shown in the cross-sectional view of Figure 1, a vibration-damping steel plate made by adhering a steel plate 5.5 with a viscoelastic resin 6 such as polyethylene, polyamide, etc. There are lightweight plates and plates made by sandwiching and gluing resin 6', and they are widely used as structural members for automobiles.Generally, when sand-inch steel plates and sand-inch steel plates are butt welded, CO2 air is emitted. In all cases of plano welding, electron beam welding, and laser welding, welding is difficult because a crack occurs due to the combustion of the resin 6, 6', and the welding area 3 is difficult to weld. Also, cross section l in Figure 2'! As shown in 2ik, sufficient strength cannot be obtained for hole 7 expansion.

nm, width 25 m'rn'l) When the welding strength was investigated when the rust-through steel plate test pieces were welded, as shown in Figure 6, the beam clearance cb was 0, compared to the case where the beam clearance cb was O. It was demonstrated that the welding strength increases when the thickness is 1 to 0.3 mlm.
