Iingxaki zoqhagamshelwano
1. uqhagamshelo lwebholithi yamandla aphezulu
1) Umphezulu wesixhobo sebholiti awuhambelani neemfuno, okukhokelela ekufakweni kakubi kweebholiti, okanye iqondo lokubopha iibholiti alihambelani neemfuno zoyilo.
Uhlalutyo lwesizathu:
a).Nantsi i-rust edadayo, i-oyile kunye nokunye ukungcola kumphezulu, kwaye kukho i-burrs kunye ne-welding tumors kwi-bolt hole.
b).Umphezulu webholithi useneziphene emva konyango.
Izisombululo:
a).I-rust edadayo, i-oyile kunye neziphene zomngxuma we-bolt kumphezulu weebholiti zamandla aphezulu kufuneka zicocwe nganye nganye.Ngaphambi kokusetyenziswa, kufuneka iphathwe nge-anti-rust.Iibholithi kufuneka zigcinwe kwaye zikhutshwe ngumntu okhethekileyo.
b).Ukucutshungulwa kwendawo yendibano kufuneka kuthathelwe ingqalelo ukulandelelana kokwakhiwa kunye nokufakwa, ukuthintela ukuphindaphinda, kwaye uzame ukujongana nayo ngaphambi kokuphakanyiswa.
2) Umonakalo we-bolt screw, i-screw ayikwazi ukujija kwi-nut, echaphazela i-bolt assembly.
Uhlalutyo lwesizathu: isikrufu sigrulisiwe kakhulu.
Izisombululo:
① Iibholiti kufuneka zikhethwe ngaphambi kokusetyenziswa, kwaye zilungelelaniswe kwangaphambili emva kokucoca umhlwa.
② Iibholiti ezonakaliswe sisikrufu azinakusetyenziswa njengeebholiti zethutyana, kwaye akuvumelekanga ngokungqongqo ukunyanzeliswa kwi-screw hole.
③ Idibaniso yebholithi kufuneka igcinwe ngokweseti kwaye akufuneki itshintshwe xa isetyenziswa.
2. Ingxaki yomgca we-welding: kunzima ukuqinisekisa umgangatho;Imiqadi ephambili kunye neentsika zomgangatho azifakwanga;Ipleyiti yeArc ayisetyenziselwa ukuwelda.
Izisombululo: Ngaphambi kweWeld Steel Structure, khangela ukuvunywa komgangatho we-welding intonga, ukuwelda kwesatifikethi sokuhlolwa kwemvume, ngokweemfuno zoyilo lokukhetha intonga ye-welding, ngokwemiyalelo kunye neenkqubo ezifuna ukusebenzisa intonga ye-welding, i-weld surface kufuneka isebenze. ungabinayo i-crack, weld beading.I-weld yokuqala kunye neyesibini iya kuba ne-porosity, i-slag, i-crater crack.I-weld ayiyi kuba neziphene ezifana nokuluma emphethweni kunye ne-welding engagqibekanga.Uvavanyo lokuqala kunye nolwesibini weld nondestructive ngokungqinelana neemfuno, Khangela isitampu welder kwi welds ezichaziweyo kunye nezikhundla.Iiwelds ezingafanelekanga aziyi kuqhutyelwa phambili ngaphandle kokugunyaziswa, guqula inkqubo ngaphambi kokucubungula.Inani lokulungiswa kwe-weld kwinqanaba elifanayo aliyi kuba ngaphezu kwamaxesha amabini.
