Na'urar walda ta Laser tana da fasa a cikin walda

Babban dalilai na fashewar injin walƙiya na laser sun haɗa da saurin sanyaya sauri, bambance-bambance a cikin kayan kaddarorin, saitunan sigar walda mara kyau, da ƙarancin ƙirar walda da shirye-shiryen walda. "

1. Da farko dai, saurin sanyaya da sauri shine babban dalilin fashewa. A lokacin aikin walda na Laser, wurin walda yana da sauri mai zafi sannan kuma yayi sanyi da sauri. Wannan saurin sanyaya da dumama zai haifar da matsananciyar zafi a cikin karfe, wanda zai haifar da tsagewa. "

2. Bugu da kari, daban-daban na karfe kayan da daban-daban thermal fadada coefficients. Lokacin walda abubuwa daban-daban guda biyu, tsagewa na iya faruwa saboda bambance-bambancen haɓakar thermal. "

3. Saituna mara kyau na sigogi na walda kamar wutar lantarki, gudu, da tsayin hankali kuma zai haifar da rarraba zafi mara daidaituwa a lokacin walda, yana shafar ingancin walda har ma da haifar da fasa. "

4. The waldi surface area ne ma kananan: Girman Laser waldi tabo ya shafi Laser makamashi yawa. Idan wurin walda ya yi ƙanƙanta, za a haifar da damuwa mai yawa a yankin, wanda zai haifar da tsagewa. "

5. Rashin ƙirar walda da shirye-shiryen walda suma sune mahimman abubuwan da ke haifar da fasa. Rashin daidaiton lissafi na walda da ƙira na iya haifar da ƙaddamarwar damuwa na walda, kuma tsaftacewa mara kyau da pretreatment na farfajiyar walda zai shafi inganci da ƙarfin walda kuma cikin sauƙin kai ga fasa.

Ga waɗannan matsalolin, ana iya ɗaukar mafita kamar haka:

1. Sarrafa yawan sanyaya, rage jinkirin sanyaya ta hanyar preheating ko yin amfani da retarder, da dai sauransu don rage tarin damuwa na thermal;

2. Zaɓi kayan da suka dace, yi ƙoƙarin zaɓar kayan da irin waɗannan nau'ikan haɓaka haɓakar thermal don waldawa, ko ƙara ƙirar kayan canzawa tsakanin abubuwa daban-daban guda biyu;

3. Haɓaka sigogin walda, daidaita daidaitattun sigogin walda bisa ga halaye na kayan welded, kamar rage ƙarfin da ya dace, daidaita saurin walda, da sauransu;

4. Haɓaka farfajiyar walda: Yadda ya kamata haɓaka wurin walda zai iya rage damuwa da tsagewar matsalolin da ƙananan walda ke haifar da su.

5. Yi pretreatment na abu da kuma bayan walda magani, cire datti kamar man fetur, sikelin, da dai sauransu daga walda part, da kuma amfani da zafi magani hanyoyin kamar annealing da tempering don kawar da walda ragowar danniya da kuma inganta taurin welded hadin gwiwa. .

6. Yi maganin zafi na gaba: Ga wasu kayan da ke da wuya a guje wa fashewa, za a iya yin maganin zafi mai dacewa bayan walda don kawar da damuwa da ke haifar bayan waldawa da kuma guje wa faruwar fashewa.
