Maxay yihiin faraantiyada wax-soo-saarka leh?

Giraantu waxa loola jeedaa tuubada birta ah ee aan xidhnayn ee kulul ama qabow-duuban (qabow sawiran) si loogu sameeyo giraanta duuban ee caadiga ah.Dhexroorka dibadda ee tuubada birta waa 25-180mm, dhumucdiisuna waa 3.5-20mm, taas oo loo qaybin karaa sax caadi ah iyo sax sare.

Shuruudaha farsamada ee soo saarista siddooyinku waa kuwo adag.Qalabka kiimikada, sifooyinka farsamada, waxqabadka habka, cabbirka hadhuudhka, qaabka carbide, qoto dheer ee lakabka decarburization, iwm ee alaabta la dhammeeyey ayaa looga baahan yahay inay buuxiyaan shuruudaha heerarka ku habboon.
