Zvinetso zvewelding dzimwe nguva zvinosangana panguva yekuiswa kwekabhoni simbi machubhu. Saka, sei weld machubhu? Chii chatinofanira kucherekedza kana tichishongedza kabhoni simbi machubhu?

1. Gasi welding
Gasi welding inogona kushandiswa kugadzira, kusanganisa gasi rinopisa uye gasi rinotsigira kupisa pamwe chete, kuishandisa senzvimbo yekupisa yemurazvo, wobva wanyunguduka nekusonedza mapaipi pamwechete.

2. Arc welding

Arc welding inogonawo kushandiswa, kureva, arc welding inoshandiswa senzira yekugadzira. Chitubu chekupisa chinobatanidza mapaipi pamwe chete. Iyi welding nzira inowanzoshandiswa mukugadzirwa kwemaindasitiri. Pamusoro penzira mbiri dziri pamusoro apa, iyo welded pipeline inogonawo kushandisa contact welding, uye nzira chaiyo yekusungirirwa inobva pane zvinhu uye zvinodiwa zvepombi.

Simbi ine simbi uye kabhoni ine zvidiki zvidiki zvakasiyana-siyana, senge manganese, chromium, silicon, vanadium, uye nickel. Yakaderera kabhoni simbi ine chete 0.3 muzana kabhoni, ichiita kuti ive nyore kwazvo kubatanidza.
Kabhoni yepakati ine 0.30 kusvika 0.60 muzana kabhoni, uye yakakwira kabhoni simbi pa 0.61 kusvika 2.1 muzana kabhoni. Kana tichienzanisa, simbi yakakandwa ine inosvika 3 muzana kabhoni, izvo zvinoita kuti zviome zvakanyanya kupinza.

Carbon steel tube welding precautions:

1. Pamberi pepombi yakasungirirwa, zvakakosha kubvisa tsvina yose mupombi. Mushure mekunge kuvakwa kwapera, ndiro yekuvhara inogona kushandiswa kuisimbisa kudzivirira marara kubva pakuwira mairi. Panguva imwecheteyo, tisati tasveta, zvinodikanwa kupurudzira mavara emafuta pachikamu chemuromo kusvikira simbi-yakafanana nekupenya ichioneka.

2. Kazhinji kutaura, iyo pombi zvinhu ndeye spiral welded pombi, saka nzira yewelding yemanyorero arc inogona kusarudzwa. Kune rudzi urwu rwepombi, ese mawelds anofanirwa kuiswa pasi ne argon arc welding, uye chivharo chinoda kunge Chizadza nemanyorero arc welding.
