Q235 uye Q345 kutaridzika kazhinji haionekwe.Musiyano wemuvara hauna chekuita nezvinhu zvesimbi, asi mutsauko wenzira yekutonhora mushure mekunge simbi yabviswa.Nzvimbo yakajairika, yakatonhodzwa zvechisikigo yakatsvuka.Kana iyo nzira yekudzima ikashandiswa, iyo nzvimbo inoumba dense oxide layer, iyo ichaita seyakasviba.

General simba dhizaini neQ345, nekuti Q345 yakakwirira kupfuura Q235 simbi simba, simbi mudunhu, kupfuura 235 mudunhu 15% - 20%.Zvakanaka kushandisa Q235 paunenge uchigadzira kudzora kugadzikana.Pane musiyano we3% kusvika 8% mumutengo.

Nekuda kwekuzivikanwa, kune akati wandei dzidziso:

A:1.Mufekitori, welding yekuyedza inogona kushandiswa kusiyanisa zvinhu zviviri izvi.Semuyenzaniso, shandisa maelectrodes eE43 kusonerera simbi diki yeraundi pane imwe neimwe yemarata maviri esimbi, wobva waisa simba rekugera kuti rinyatsosiyanisa zvinhu zvemarata maviri esimbi zvichienderana nemamiriro ezvinhu panguva yekutadza.

2. Mufekitori, vhiri rekukuya rinogona kushandiswa kusiyanisa zvinhu zviviri.Kana simbi yeQ235 ikakwenenzverwa negumbo rekukuya, pfarivari dzinobhururuka dzichibuda dzakatenderera dzine ruvara rwakasviba.Q345's spark ine bifurified uye inopenya.

3, kune zvakare maererano nemusiyano wemuvara weshear pamusoro pemhando mbiri dzesimbi dzinogona kusiyaniswa pakati pemhando mbiri dzesimbi.Kazhinji, chiteshi chekucheka cheQ345 chichena muruvara.

B:1.Zvinoenderana nerudzi rwendiro yesimbi, zvinhu zveQ235 neQ345 zvinogona kusiyaniswa: ruvara rweQ235 iblue, uye ruvara rweQ345 rwumwe rutsvuku (izvi ndezvesimbi ichangopinda mumunda, uye inogona kusasiyaniswa mushure menguva refu).

2, iyo inonyanya kukwanisa kusiyanisa zvinhu zvebvunzo ndeyekuongorora kwemakemikari, Q235 uye Q345 kabhoni yemukati haina kufanana, panguva imwe chete iyo kemikari yemukati haina kufanana.(Iyi inzira yechokwadi yekuzviita.)

3, Q235 uye Q345 mutsauko wezvinhu, ine welding modhi: izvo zviviri zvisingazivikanwe zvesimbi simbi butt, ine yakajairwa welding tsvimbo kuti weld, kana divi rakatsemuka resimbi ndiro yakaratidza kuve Q345 zvinhu.(Ichi chiitiko chinoshanda)
