Paunenge uchitsvaira pombi dzesimbi, unofanirwa kuterera kune zvinotevera:
Kutanga, chenesa pamusoro pepombi yesimbi. Usati wapinza, ita shuwa kuti pamusoro pepombi yesimbi yakachena uye haina mafuta, pendi, mvura, ngura, uye zvimwe zvitsvina. Izvi zvinosvibisa zvinogona kukanganisa kufambira mberi kwakanaka kwewelding uye zvinogona kutokonzera nyaya dzekuchengetedza. Zvishandiso zvakadai semavhiri ekukuya nemabhurashi ewaya zvinogona kushandiswa kuchenesa.
Chechipiri, kugadziriswa kwebevel. Zvinoenderana nehupamhi hwemadziro epombi yesimbi, gadzirisa chimiro uye saizi yewelding groove. Kana madziro emadziro akakora, groove inogona kunge yakakura zvishoma; kana madziro emadziro ari mutete, groove inogona kuva diki. Panguva imwecheteyo, kutsetseka uye kupfava kwegorofu kunofanirwa kuve nechokwadi chekugadzirisa zvirinani.
Chechitatu, sarudza nzira yakakodzera yewelding. Sarudza iyo yakakodzera welding nzira zvinoenderana nezvinhu, zvakatemwa, uye welding zvinodiwa zvepombi yesimbi. Semuenzaniso, kune mahwendefa matete kana mapaipi epasi-kabhoni simbi, gasi shielded welding kana argon arc welding inogona kushandiswa; kune mahwendefa akakora kana zvimiro zvesimbi, yakanyura arc welding kana arc welding inogona kushandiswa.
Chechina, kudzora ma parameters e welding. Welding parameters zvinosanganisira welding current, voltage, welding speed, etc. Aya maparameter anofanirwa kugadziriswa maererano nezvinhu uye ukobvu hwepombi yesimbi kuti ive nechokwadi chekushongedza uye kushanda zvakanaka.
Chechishanu, teerera kune preheating uye post-welding kurapwa. Kune imwe yakakwirira-kabhoni simbi kana alloy simbi, preheating kurapwa kunodiwa usati welding kuderedza welding kushushikana uye kudzivirira kuitika kwekutsemuka. Post-weld kurapwa kunosanganisira weld kutonhora, welding slag kubviswa, nezvimwe.
Pakupedzisira, tevera nzira dzakachengeteka dzekushanda. Munguva yewelding process, kutarisisa kunofanirwa kubhadharwa kune yakachengeteka maitiro ekushanda, sekupfeka zvipfeko zvekudzivirira, magirovhosi, uye masks. Panguva imwecheteyo, midziyo yewelding inofanirwa kuongororwa uye kuchengetedzwa nguva nenguva kuti ive nechokwadi chekushanda kwayo.
