Embodiment 1
[0032] 1) The welding base material is T2 pure copper, the machining specification is 10×5×1.5mm, and the machining specification of 1060 pure aluminum plate is 10×5×1mm;
[0033] 2) Select 600# coarse sandpaper for dry grinding on the end faces of copper and aluminum metal parts, and then use 2500# fine sandpaper for wet grinding;
[0034] 3) Perform 12min ultrasonic decontamination treatment on the end faces of the polished copper and aluminum metal parts;
[0035] 4) Connect the treated copper metal end face to the aluminum metal end face, control the pressure of the pressure device to 30N to fix the metal parts, and perform laser welding in an argon atmosphere. The argon flow rate is 10L / min, and the laser power is 1200W. Speed 5mm / s.
[0036] 5) After the welding is completed, while the pressure applied by the metal parts is released, the copper and aluminum metal parts are stretched outward through the pressure regulating plate to release the stress after welding.
