Indlela yokuhlukanisa impahla yensimbi yensimbi yi-Q235 ne-Q345?

I-Q235 Steel PlatefuthiI-Q345 Steel Platengokuvamile azibonakali ngaphandle. Umehluko wombala awuhlangene nempahla yensimbi, kodwa ubangelwa izindlela zokupholisa ezihlukene ngemva kokuba insimbi ikhishwa. Ngokuvamile, ubuso bubomvu ngemva kokupholisa kwemvelo. Uma indlela esetshenzisiwe iwukupholisa ngokushesha, ubuso bokwakheka kwengqimba ye-oxide eqinile, izobonisa umnyama.
Isakhiwo esijwayelekile samandla nge-Q345, ngoba i-Q345 kune-Q235 amandla ensimbi, gcina insimbi, kune-235 yonga 15% - 20%. Ukuklama kokulawula ukuzinza nge-Q235 enhle. Umehluko wentengo ka-3% --- 8%.

Ngokuqondene nokuhlonza, kunezitatimende eziningana:
A.
1, ifektri ingasetshenziswa ukuhlola izindlela zokushisela ukuze zihlukanise cishe phakathi kwezinto ezimbili. Ngokwesibonelo, e izingcezu ezimbili steel plate nge E43 Welding induku abangu ashiselwe insimbi encane eyindilinga, bese usebenzisa amandla phuca, ngokusho ukucekelwa phansi isimo ukuhlukanisa phakathi kwezinhlobo ezimbili steel plate impahla.
2, imboni ingase futhi isebenzise isondo lokugaya ukuze ihlukanise cishe phakathi kwezinto ezimbili. Insimbi ye-Q235 enesondo lokugaya lapho igaya, izinhlansi ziyizinhlayiya eziyindilinga, umbala omnyama. Futhi izinhlansi ze-Q345 zihlukene kabili, zinemibala egqamile.
3, kukhona futhi ngokusho ezimbili steel phuca surface umbala umehluko ungakwazi futhi ukuhlukanisa phakathi izinhlobo ezimbili zensimbi. Okujwayelekile, umbala womlomo we-shear we-Q345 omhlophe
B.
I-1, ngokusho kombala wepuleti yensimbi ingahlukanisa phakathi kwe-Q235 ne-Q345 impahla: umbala we-Q235 oluhlaza, i-Q345 enye ebomvu (lokhu kuphela endaweni yensimbi, isikhathi asikwazi ukuhlukaniswa)
2, ukuhlolwa kwezinto ezibonakalayo okuhlukaniseka kakhulu ukuhlaziya amakhemikhali, i-Q235 ne-Q345 okuqukethwe kwekhabhoni akufani, kuyilapho okuqukethwe kwamakhemikhali akufani. (Lena yindlela engenangqondo)
3, umehluko phakathi kwe-Q235 ne-Q345 impahla, ene-welding: izingcezu ezimbili zezinto ezingaziwa ze-butt yensimbi, enenduku evamile yokushisela ukushisela, uma kukhona ukuqhekeka ohlangothini olulodwa lwepuleti lensimbi kufakazelwa ukuthi yi-Q345 impahla. (Lokhu okuhlangenwe nakho okungokoqobo)
