Silig Welding Adag oo gaashaaman
Waqtigan xaadirka ah, abuurista iyo adeegsiga siligga alxanka gaaska ee CO2 waa mid aad u kobcaya, iyadoo qaar ka mid ah waddamada horumaray sida kuweena ay ku xisaabtamayaan 40-50% wadarta alxanka.Waxay caan ka helaysaa maalinba qaybo badan, iyadoo si tartiib tartiib ah u bedelaysa alxanka gacanta.Mid ka mid ah faa'iidooyinka muhiimka ah waa qiimaha alxanka oo hooseeya, taas oo ka dhigaysa mid ka dhaqaale badan farsamooyinka alxanka kale.
Siligga alxanka ee gaashaaman ayaa sidoo kale ku faana waxtarka wax soo saarka sare iyo isticmaalka tamarta hooseeya, taas oo ka dhigaysa mid ku habboon mashaariicda alxanka sare.Waxa kale oo aad u fudud in lagu shaqeeyo, maadaama ay u oggolaanayso alxanka dhammaan jagooyinka, oo ay ku jiraan alxanka sare.Tani waxay ka dhigaysaa mid ku habboon alxanka meelaha cidhiidhiga ah ama xaglaha adag.
Intaa waxaa dheer, alxanka leh CO2 silig alxanka gaashaamsan ayaa bixiya tayo gaar ah.Iyada oo ay ku yar tahay maadada haydaroojiin iyo ka kooban nitrogen yar, alxanka ayaa leh iska caabin dildilaac ah oo aad u wanaagsan.Welds sidoo kale waxay leeyihiin cillado yar ka dib marka la dhammeeyo, taasoo ka dhigaysa mid ku habboon xitaa mashaariicda alxanka ee ugu jilicsan.Siligga ayaa sidoo kale bixiya wax badan oo kala duwan maadaama ay ku habboon tahay alxanka dhuuban, dhexdhexaad ah, iyo taarikada qaro weyn.
Gebagebadii, Xadhkaga Alxanka Adag ee Gaaska-Gaashaanku waa mid lagama maarmaan u ah habka alxankaaga, faa'iidooyinkeeda tirada badanna waxay ka dhigaan mid aan laga adkaan karin farsamooyinka alxanka kale.Iyada oo leh tayo aad u fiican, qiimo jaban, hufnaan sare, iyo sahlan isticmaalka, waxay si dhakhso ah u noqonaysaa farsamada alxanka ee la door bidayo meelo badan.Dooro kan ugu fiican, oo la kulan natiijooyin aad u wanaagsan silig-alxanka adag ee Gaas-gaashaasha.
