The invention relates to a current-carrying inertial axial friction composite welding method and equipment thereof. In the inertial axial friction welding process, a unique current loading method without an electric brush is adopted, current is introduced into a friction welding head to enable a friction interface to generate resistance heat, and the resistance heat and friction heat form a friction composite heat source for together heating joints and carrying out friction and plastic deformation to realize the purpose of welding through the method and the equipment. The method and the equipment can shorten the heating time of friction welding, improve the production efficiency of welding, the friction pressure, the power of a main shaft and the special requirements for the capacity of a friction welding machine, can adopt resistance heat to carry out heat treatment after welding and preheating before welding on welding seams and improve the structure property of joints, and are especially suitable for friction welding of rotator joints of high-melting point and high-hardness dissimilar materials, small-size pipes or bars and the like.

This is a process method of a pure Au and alloy LED. It is composed by a P-N expending slice, pure Au filling layer, alloy filling layer and a silicon underlay of reflection layer. The P-N expending slice includes a sapphirine underlay, a N-GaN layer on the underlay, a P-GaN layer on the N-GaN layer and a reflection layer in between. A metal layer which is good for current diffusion is deposited on the P-GaN layer. A P / N electrode is led from the P-GaN layer and the N-GaN layer separately. An isolation layer is formed in between the P / N electrode. An electric insulation layer is formed on a silicon underlay, to the top formed a metal reflection layer. The P-N expending slice is heat jointed with the silicon underlay by filling in pure Au and alloy.

The invention discloses a method for preparing a formwork with controllable heat dissipation conditions. On the part of the formwork that needs to be adjusted for heat dissipation conditions, a profiling low-ignition substance of a shape corresponding to the adjusted position is pasted. The upper end of the profiling low-ignition substance has a There is a drainage tube; after the mold shell is prepared, the profiling low-flammability substance is removed to form a corresponding hollow part, and the hollow part is vacuumed or filled with materials with different thermal conductivity through the drainage tube to control the thermal conductivity of the corresponding position. The invention is simple and convenient to operate. For the thin-walled area of ​​the casting, the heat transfer coefficient can be small and the heat dissipation slow, so as to ensure that the casting is not under-cast and columnar crystals caused by temperature gradients are not generated. For the relatively thick part of the casting and the area where the hot joint is prominent, the heat transfer coefficient can be made large and the heat dissipation can be fast, so as to avoid the looseness of the casting at this place.
