Kukwira chubhu-kune-shiti welding kunoda kupinza midzi uye kuumbwa kwakanaka kwemusana, saka kushanda kwakanyanya kuoma. Zvinoenderana nenzvimbo dzakasiyana dzenzvimbo, iyo yekugara chubhu-shiti welding inogona kupatsanurwa kuita mhando nhatu: vertical fixed flat fillet welding, vertical fixed elevation angle welding uye horizontal fixed fillet welding.
Nhasi ndichataura newe nezve vertical fixed welding yekutasva chubhu sheet.
Ona mufananidzo uri pazasi wekona pakati petochi yewelding, welding waya uye workpiece.
Tack welding inowanzobatanidzwa neinopindirana waya yekuzadza nzira. Kureba uye nhamba yemateki welds inotarwa zvichienderana nehupamhi hwepombi, kazhinji 2 kusvika 4 zvikamu, chikamu chimwe nechimwe chine 10 kusvika 20mm kureba. Paunenge uchitsigira welding, tanga warova arc pane tack weld, zunza arc in situ, uye mirira kuti tack weld inyauke kuti igadzire dziva rakanyungudutswa rakagadzika, wozadza waya uye weld kuruboshwe kuti uve nechokwadi chekuti kumashure kwakanaka. akaumbwa.
Munguva yekugadzira, dziva rakanyungudutswa rinofanirwa kucherechedzwa chero nguva, uye kona iri pakati petochi yewelding nendiro yepasi inofanira kugadziridzwa zvakakodzera kuti ive nechokwadi chekuti saizi yegomba rakanyungudutswa rinoenderana uye rinodzivirira kupisa-kuburikidza. Kana welding kune mamwe ma tack welds, kudyisa waya kunofanirwa kumiswa kana kuderedzwa kunyungudutsa ma tack welds uye kuita shanduko yakatsetseka neyakapfuura pasi welds.
Kana iyo arc yadzimwa, dzvanya switch, ikozvino inotanga kuora, uye waya yekudyisa inomira mushure mekunge arc crater yazadzwa. Mushure mekunge arc yadzimwa, dziva rakanyungudutswa rinooma. Panguva ino, tambo yekushongedza uye tambo yekushongedza inofanira kuramba ichichengetwa munzvimbo, uye mwenje wekupisa unofanirwa kubviswa mushure mekunge gasi ramiswa. Kana uchibatanidza, rova arc panzvimbo 10-15 mm kuseri kwearc crater, uye fambisa arc kujoini nekukurumidza zvishoma; mushure mekunge arc crater yepakutanga yanyunguduka kuita dziva rakanyungudutswa, wobva wazadza waya welding. Kana paine bundu repano pazasi welding bead, shandisa angle grinder kuikuya sandarara usati waita cover welding.
Panguva yekuzadza welding kana kuvhara kwevhavha, mutsara wekutenderera we torch welding yakakura zvishoma, kuitira kuti mitsetse ye groove yepombi uye ndiro yakanyunguduka zvizere. Iyo weld yekuzadza haifanirwe kunge yakafara kana yakanyanya kukwirira, uye iyo yepamusoro inofanira kunge yakati sandara.
Welding yevhavha dzimwe nguva inoda mawelds maviri, uye yepasi inofanira kutanga yaiswa weld, ichiteverwa neyekumusoro. Kana uchisungirira bead iri pazasi, arc inotenderedza kumucheto kwezasi kwebead, uye mupendero wepamusoro wedziva rakanyungudutswa unodzorwa pa 1/2 kusvika 2/3 ye bottoming weld, nepo mupendero wezasi wedziva rakanyungudutswa uri. inodzorwa pamateru 0.5-1.5 mm pazasi pemucheto wezasi wemuromo. Paunenge uchimoneredza bhedhi repamusoro, arc inofanirwa kutenderedza kumucheto kwekumusoro kwebead, kuitira kuti mupendero wepamusoro wedziva rakanyungudutswa upfuure kumucheto kwekumusoro kwegorovha ne 0.5-1.5mm, uye kumucheto kwepasi kwechidziva chakanyungudutswa. zvakanaka nebead rezasi kuti uve nechokwadi chekuti weld seam Iyo yepamusoro inotsvedzerera uye yakaenzana.
