Ingaphakathi laseMongolia yokugcina amalahle kwiyadi semicircular isithuba isakhelo isakhiwo, ukuphakama iyonke 41 yeemitha, ubude bubonke 93 yeemitha, bubonke ubude 500 yeemitha.
1. Izinto zombhobho wensimbi kufuneka zihambelane nentsimbi ye-Q235B echazwe kwi-"Carbon Structural Steel" GB700 kunye nombhobho wensimbi odibeneyo ochazwe yi-GB3092 okanye i-No.
2. Ibhola yebholithi yenziwe ngentsimbi ye-45 echazwe kwi-GB699, kwaye umphezulu kufuneka ube bushelelezi, kungabikho zintanda, kungabikho ukutshisa, kwaye akukho pitting.
3. Iibholiti eziphakamileyo eziphezulu zenziwe ngezinto ezichazwe kwi-GB / T16939-1997 "Iibhotshi eziphezulu zentsimbi yeentsimbi zegridi kunye namalungu ebhola".Imveliso egqityiweyo ayikuvumeli ukucima iintanda zaluphi na ubunzulu okanye naluphi na ubude kuyo nayiphi na indawo.Umgangatho wokusebenza weebholithi zokuqina okuphezulu kufuneka uhlangabezane neemfuno ze-"Steel High-strength bolts for grid bolts and ball joints "GB/T16939-1997", ubunzima bomphezulu kufuneka bufikelele kwi-HRC32~36, umsonto kufuneka uhlangane nenqanaba le-6g "General Thread Tolerance and Fit" GB197, kwaye umphezulu kufuneka ube mnyama kwaye ipeyintiwe.
4. Izinto eziphathekayo zepleyiti yokutywina kunye nentloko ye-cone kufuneka ihambelane ne-Q235 yensimbi echazwe kwi-GB700, kwaye izinto ze-sleeve kunye ne-sleeve kufuneka zihambelane ne-Q235 yensimbi echazwe kwi-GB700 okanye i-16Mn yentsimbi echazwe kwi-"Technical Conditions for I-Low Alloy Structural Steel" GB1591 okanye "iSakhiwo seKhabhoni ePhezulu".Kwinombolo ye-45 yensimbi echazwe kwi-GB699, ukubonakala kwepleyiti yokutywina, intloko ye-cone kunye nomkhono awuyi kuba nokuqhekeka, ukutshisa ngokugqithiseleyo kunye nesikali.
5. Intonga ye-Welding: Uchungechunge lwe-E43XX lukhethiwe;Iimfuno zebakala lokudityaniswa kwe-weld: i-weld ye-butt yombhobho oyintloko yi-weld yokungena epheleleyo, kwaye ibakala lomgangatho we-weld linqanaba lokuqala.Umgangatho womgangatho wezinye ii-welds zokungena ngokupheleleyo yiKlasi ye-II;
I-6 Izinto eziphathekayo kufuneka zibe nezatifikethi ezisemgangathweni kunye neengxelo zokwamkelwa, iibhola zetsimbi kufuneka ziphawulwe ngamanani omsebenzi, zonke ii-weldments kufuneka zifakwe kwiinombolo zemisebenzi ye-welder, kunye nomgangatho wazo zonke iimveliso kufuneka zihambelane ne- <> JGJ75.1~75.3-91
7. Intsimbi esetyenziswe kwisakhiwo esithwala umthwalo kufuneka sibe nesatifikethi samandla e-tensile, elongation, amandla okuvelisa kunye nesulfure kunye nomxholo we-phosphorus.
Intsimbi esetyenzisiweyo kwizakhiwo ezinomthwalo odibeneyo kunye nezakhiwo ezibalulekileyo ezingenayo i-welded ezithwala imithwalo nazo ziya kuba nesatifikethi sovavanyo lokugoba olubandayo.
