Astaamaha birta ee walxaha
Tuubooyinka alxanka leh ee dhererkoodu hooseeyo ayaa laga soo saaraa birta, halka tuubooyinka alxanka leh laga soo saaro gariiradaha duuban ee kulul.Geedi socodka xariijimaha kulul ee duuban wuxuu leeyahay faa'iidooyin dhowr ah wuxuuna leeyahay habka birta ee awood u leh inuu helo wax soo saarka birta khadka birta oo tayo sare leh.Tusaale ahaan, istaaga wax soo saarka ayaa lagu qalabeeyaa nidaamka qaboojinta biyaha si loo dardargeliyo qaboojinta, taas oo u oggolaanaysa isticmaalka isku-dhafka hoose ee hoose si loo gaaro darajooyinka xoogga gaarka ah iyo heerkulka hooseeya, taas oo hagaajinaysa weldability ee birta.Si kastaba ha ahaatee, nidaamkan ayaa inta badan ka maqan dhirta wax soo saarka birta.Maaddada daawaha (kaarboonka u dhiganta) gariiradda ayaa inta badan ka hooseeya kuwa darajooyinka la midka ah ee taarikada birta, taas oo sidoo kale wanaajisa alxanka tubooyinka alxanka leh.
More muhiim ah in la ogaado waa in, sababta oo ah gariiradda gariiradda tuubada welded spiral ma aha toosan in ay jihada dhidibka birta birta ah (xalka qanjaruufo ay ku xiran tahay xagal wareeg ah ee birta birta), halka tollayn toosan birta saxan bir duuban. jihada toosan in ay jihada dhidibka birta birta, oo sidaas daraaddeed, wax tuubada welded wareegyada waa ka fiican yahay iska caabin dildilaaca bir toosan.
Habka alxanka
Laga soo bilaabo habka alxanka, tuubada welded spiral iyo habka alxanka birta toosan tollayn waa isku mid, laakiin tollayn toosan biibiile welded lama huraan yeelan doonaan wax badan oo alxanka alxanka, si fursadaha cilladaha alxanka si weyn u kordhay, iyo stress haraaga ah ee alxanka. alxanka ding waa ka weyn yahay, biraha alxanka ayaa inta badan ku jira xaalad walaac saddex geesood ah, kordhinaysa suurtagalnimada dildilaaca.
Waxaa intaa dheer, marka loo eego habka alxanka qulqulka, alxan kasta waa inuu ahaadaa bilawga arc iyo bakhtiiminta, laakiin tuubo kasta oo toosan oo welded tuubo ah oo ku jirta tolida welded annular, ma gaari karto xaaladda, sidaas awgeed waxaa laga yaabaa inay jiraan cillado alxanka oo badan oo ku yaal arc. daminta.
