Ungazihlukanisa njani izinto zepleyiti yentsimbi phakathi kwe-Q235 kunye ne-Q345?

Ipleyiti yentsimbi ye-Q235kwayeIpleyiti yentsimbi ye-Q345ngokubanzi azibonakali ngaphandle. Umahluko wombala awunanto yakwenza nezinto ezenziwe ngentsimbi, kodwa ubangelwa ziindlela ezahlukeneyo zokupholisa emva kokuba intsimbi iqengqelekile. Ngokubanzi, umphezulu ubomvu emva kokupholisa kwendalo. Ukuba indlela esetyenzisiweyo kukupholisa ngokukhawuleza, umphezulu wokwenziwa komaleko we-oxide exineneyo, uya kubonisa umnyama.
Uyilo lwamandla ngokubanzi olune-Q345, kuba i-Q345 inamandla entsimbi kune-Q235, gcina intsimbi, kune-235 gcina i-15% - 20%. Uyilo lolawulo lozinzo olune-Q235 elungileyo. Umahluko wexabiso yi-3% --- 8%.

Ngokuphathelele ukuchonga, kukho iingxelo ezininzi:
A.
1, umzi-mveliso ungasetyenziselwa ukuvavanya iindlela zokuwelda ukuze kwahlulwe phakathi kwezinto ezimbini. Umzekelo, kwipleyiti yentsimbi ezimbini nge-E43 welding rod kwadityaniswa intsimbi encinci engqukuva, emva koko kwasetyenziswa amandla okucheba, ngokwendlela etshatyalaliswa ngayo imeko ukuze kwahlulwe phakathi kweentlobo ezimbini zezinto zepleyiti yentsimbi.
2, umzi-mveliso ungasebenzisa ivili lokusila ukwahlula phakathi kwezi zinto zimbini. Intsimbi ye-Q235 enevili lokusila xa isila, iintlantsi zingqukuva, zinombala omnyama. Kwaye iintlantsi ze-Q345 zinombala oqaqambileyo, oxutyiweyo.
3, kukho umahluko phakathi kombala wentsimbi emibini, umahluko phakathi kweentlobo ezimbini zentsimbi ungahlula phakathi kweentlobo ezimbini zentsimbi. Ngokubanzi, umbala womlomo we-Q345 shear omhlophe
B.
1, ngokwemibala yepleyiti yentsimbi, ungahlula phakathi kwezinto ze-Q235 kunye ne-Q345: umbala we-Q235 kumbala oluhlaza, umbala we-Q345 obomvu (oku kuxhomekeke kuphela kwicandelo lentsimbi, ixesha alinakwahlulwa)
2, uvavanyo lwezinto ezibonakalayo luhlalutyo lweekhemikhali, umxholo wekhabhoni we-Q235 kunye nowe-Q345 awufani, ngelixa umxholo weekhemikhali ungafani. (Le yindlela engenamsebenzi)
3, umahluko phakathi kwezinto ze-Q235 kunye ne-Q345, kunye nokuwelda: iziqwenga ezibini zezinto ezingaziwayo zentsimbi, kunye nentonga yokuwelda eqhelekileyo yokuwelda, ukuba kukho umngxuma kwelinye icala lepleyiti yentsimbi kungqinwa ukuba zizinto ze-Q345. (Le ngamava asebenzayo)
