Usoro eletriki atọ, ya bụ batrị ike, moto na njikwa moto, bụ akụkụ bụ isi nke na-ekpebi arụmọrụ egwuregwu nke ụgbọ ala ike ọhụrụ. Akụkụ bụ isi nke akụkụ moto ahụ bụ IGBT (Insulated Gate Bipolar Transistor). Dị ka "CPU" n'ime ụlọ ọrụ eletrọnịkị ike, IGBT bụ nke mba ụwa nabatara dị ka ngwaahịa kacha nnochite anya na mgbanwe eletrọnịkị. A na-ejikọta ọtụtụ ibe IGBT ma chịkọta ọnụ iji mepụta modul IGBT, nke nwere ike dị ukwuu yana ike ikposa ọkụ. Ọ na-arụ ọrụ dị oke mkpa na mmetụta n'ọhịa nke ụgbọ ala ume ọhụrụ.
Carman Haas nwere ike ịnye ngwọta nkwụsịtụ maka ịgbado ọkụ modul IGBT. Usoro ịgbado ọkụ ahụ nwere laser fiber, isi ịgbado ọkụ nyocha, onye na-ahụ maka laser, kabinet njikwa, nkeji mmiri jụrụ oyi na modulu ọrụ inyeaka ndị ọzọ. A na-etinye laser ahụ na isi ịgbado ọkụ site na nnyefe eriri anya, wee gbanye ya na ihe a ga-agbado. Mepụta okpomọkụ ịgbado ọkụ dị oke elu iji nweta nhazi ịgbado ọkụ nke electrodes njikwa IGBT. Isi ihe nhazi bụ ọla kọpa, ọla kọpa ọla ọcha, aluminom alloy ma ọ bụ igwe anaghị agba nchara, nke nwere ọkpụrụkpụ nke 0.5-2.0mm.
1, Site ukpụhọde ngwa anya ụzọ ruru na usoro parameters, mkpa ọla kọpa Ogwe nwere ike welded enweghị spatter (elu ọla kọpa mpempe akwụkwọ <1mm) ;
2, Kwadoro na ike nlekota modul ka nyochaa laser mmepụta kwụsie ike na ozugbo;
3, Kwadebere na LWM / WDD usoro nyochaa ịgbado ọkụ àgwà nke ọ bụla weld onuete online zere ogbe ntụpọ mere site mmejọ;
4, Welding penetration bụ mụ na elu, na fluctuation nke penetration<± 0.1mm;
Ngwa nke nnukwu ọla kọpa mmanya IGBT ịgbado ọkụ (2+4mm / 3+3mm).
