Tsarin wutar lantarki guda uku, wato baturi mai ƙarfi, motar motsa jiki da mai kula da motoci, su ne ainihin ɓangaren da ke ƙayyade ayyukan wasanni na sababbin motocin makamashi. Babban ɓangaren ɓangaren tuƙin motar shine IGBT (Insulated Gate Bipolar Transistor). A matsayin "CPU" a cikin masana'antar lantarki, IGBT an san shi a duniya a matsayin mafi wakilcin samfur a cikin juyin juya halin lantarki. An haɗa kwakwalwan IGBT da yawa kuma an tattara su tare don samar da tsarin IGBT, wanda ke da ƙarfi mafi girma da ƙarfin watsar zafi. Yana taka muhimmiyar rawa da tasiri a fagen sabbin motocin makamashi.
Carman Haas na iya samar da mafita ta tsayawa ɗaya don waldawar IGBT. Tsarin waldawa ya ƙunshi fiber Laser, shugaban walda na na'urar daukar hotan takardu, mai sarrafa Laser, majalisar sarrafawa, sashin sanyaya ruwa da sauran kayan aikin taimako. Ana shigar da Laser ɗin zuwa kan waldi ta hanyar watsa fiber na gani, sannan a haskaka a kan kayan da za a yi walda. Ƙirƙirar matsanancin yanayin yanayin walda don cimma aikin walda na IGBT masu sarrafa lantarki. Babban kayan aiki shine jan karfe, jan karfe mai launin azurfa, gami da aluminum ko bakin karfe, tare da kauri na 0.5-2.0mm.
1, By daidaitawa da Tantancewar hanya rabo da aiwatar sigogi, bakin ciki sanduna jan karfe za a iya welded ba tare da spatter (babban jan karfe takardar <1mm) ;
2, Sanye take da ikon saka idanu module don saka idanu Laser fitarwa kwanciyar hankali a ainihin lokacin;
3, Sanye take da tsarin LWM/WDD don saka idanu da ingancin walda na kowane weld ɗin akan layi don guje wa lahanin tsari ta hanyar kuskure;
4. Welding shigar azzakari cikin farji ne barga da kuma high, da kuma hawa da sauka daga cikin shigar azzakari cikin farji <± 0.1mm;
Aikace-aikacen sandar jan ƙarfe mai kauri IGBT waldi (2+4mm / 3+3mm).
