Lub tank dej thiab nws cov khoom siv tau tsim los siv cov pa roj carbon zoo tib yam thiab cov qauv hlau, thiab lawv qhov zoo yuav tsum ua raws li cov qauv tam sim no "Carbon Structural Steel" thiab "Carbon Steel Welding Electrodes," feem. Cov hlau phaj ntawm lub tank saum, phab ntsa, thiab hauv qab yog tag nrho cov pob tw -welded (Kuv- hom welds rau saum phaj, V- hom welds rau hauv qab phaj thiab sab phab ntsa). Lwm cov welds yog fillet welds. Hla - zoo li cov welds tsis raug tso cai, thiab cov welds yuav tsum tsis txhob sib tshooj nrog cov tuav tuav.
Tag nrho- kuaj dej: Tom qab lub tank dej tiav lawm, sau nws tag nrho nrog dej. Tom qab 2-3 teev, maj mam txhuam cov welds nrog 0.5-1.5 kg txhuas rauj raws li kwv yees li 150 hli ntawm ob sab. Yog tias tsis pom qhov xau, qhov kev xeem yog (tsim nyog). Yog tias pom muaj cov dej xau, qhov vuam yuav tsum tau rov welded, thiab rov kuaj dua.
