Weelka Kuleyliyaha Daawaha Birta ah

Kala soocidda dhumuc ahaan

Saxan bir ah oo khafiif ah oo ka yar 4 mm (kan ugu khafiifsan 0.2 mm), saxan bir ah oo dhumucdiisu tahay 4-60 mm, saxan bir ah oo aad u dhumuc weyn 60-115 mm. Ballaca saxanka khafiifka ah waa 500-1500 mm; ballaca saxanka qaro weyn waa 600-3000 mm. Nooca birta ah ee saxan bir ah oo qaro weyn Asal ahaan waa la mid ah saxanka birta khafiifka ah. Marka laga hadlayo alaabada, marka laga reebo saxamada birta ee buundada, saxamada birta ee kuleyliyaha, saxamada birta ee wax soo saarka baabuurta, saxamada birta ee weelka cadaadiska iyo saxamada birta ee weelka cadaadiska badan leh, kuwaas oo ah saxamada qaro weyn oo saafi ah, noocyo ka mid ah saxanada birta ah sida saxamada birta ee alwaaxa baabuurta (dhumucdoodu tahay 2.5-10 mm), qaab saxanada birta ah (dhumucdoodu tahay 2.5-8 mm), saxanada birta ah ee aan daxalka lahayn, saxanada birta ee kulaylka u adkaysta, iwm. waxaa lagu dhejiyaa saxanada khafiifka ah. 2. Saxanka birta ah waxaa loo qaybiyaa kuwa kulul oo la duubay iyo kuwa qabow iyadoo loo eegayo rogid.

Loo kala saaray ujeeddo ahaan

(1) Saxan bir ah oo buundo ah (2) Saxan bir ah oo kuleyliye ah (3) Saxan bir ah oo dhisa maraakiibta (4) Saxan bir ah oo hub ah (5) Saxan bir ah oo baabuur ah (6) Saxan bir ah oo saqafka ah (7) Saxan bir ah oo qaab dhismeed ah (8) Saxan bir ah oo koronto ku shaqeeya (xarig bir ah oo silikoon ah) (9) Saxan bir ah oo guga ah (10) Kale

Qaab-dhismeedka waxaa loo kala saaray qaab-dhismeed

1. Saxan bir ah oo loogu talagalay weelka cadaadiska: Isticmaal xaraf R si aad u muujiso dhammaadka darajada. Darajada waxaa lagu muujin karaa dhibicda wax soo saarka ama maaddada kaarboonka ama walxaha isku-darka. Sida: Q345R, Q345 waa barta wax soo saarka. Tusaale kale: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, iwm. dhammaantood waxaa matalaya walxaha kaarboonka ama walxaha isku-darka.

2. Saxan bir ah oo loogu talagalay alxanka dhululubada gaaska: Isticmaal HP-ga weyn si aad u muujiso dhammaadka darajada, darajadiisana waxaa lagu muujin karaa barta wax soo saarka, sida: Q295HP, Q345HP; waxaa sidoo kale lagu muujin karaa walxaha isku-darka, sida: 16MnREHP.

3. Saxan bir ah oo loogu talagalay kuleyliyaha: Isticmaal xarafka yar ee g si aad u muujiso dhammaadka magaca summada. Darajadiisa waxaa lagu muujin karaa barta wax soo saarka, sida: Q390g; waxaa sidoo kale lagu muujin karaa waxyaabaha kaarboonka ku jira ama walxaha isku-darka, sida 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, iwm.

4. Taarikada birta ah ee buundooyinka: Isticmaal xarfaha yaryar ee q si aad u muujiso dhammaadka darajada, sida Q420q, 16Mnq, 14MnNbq, iwm.

5. Taarikada birta ah ee loogu talagalay alwaaxa baabuurta: Isticmaal xaraf weyn oo L ah si aad u muujiso dhammaadka darajada, sida 09MnREL, 06TiL, 08TiL, 10TiL, 09SiVL, 16MnL, 16MnREL, iwm.
