welding joint process yesimbi nzvimbo furemu

Iyo weld pamusoro haifanirwe kuve nekutsemuka kana kuremara.Iwo ekutanga uye echipiri welds haazove nepamusoro pores, slag clips, arc gomba rakatsemuka, arc abrasion uye humwe hurema.Uye giredhi rekutanga weld haizove nekurumwa, kwete kuzara, midzi shrinkage uye humwe hurema.Kuongorora kuwanda: 10% yezvikamu zvakafanana zvichaongororwa, uye kwete pasi pe3;yezvikamu zvakaongororwa, imwe neimwe yemhando ye weld ichaongororwa 5% nehuwandu hwezvidimbu, uye kwete pasi pe1;iyo yakazara nzvimbo yekutarisa haizove isingasviki 10.Nzira yekuongorora: tarisa kana kushandisa magnifying glass, weld gauge uye steel gauge, nekupinda kana magnetic particle test.

Iyo welding yekubatanidza zvinhu inofanirwa kuenderana ne base simbi.Kana magiredhi maviri esimbi akasiyana akasungwa, electrode kana waya inofanana negiredhi resimbi repasi rinoshandiswa.Welded connections with direct dynamic load kana yakakosha gobvu ndiro welding inofanira kushandisa low-hydrogen electrodes, yakadai seE4315, E4316, E5015, E5016 nemamwe mamodel.Fire retardant coatings inofanira kuva zvigadzirwa zvakapfuura muedzo wesangano rekuongorora nyika uye zvave zvichiitwa. inobvumidzwa nedhipatimendi remoto, uye inofanirwa kufananidzwa neiyo primer.Kuita, kupeta ukobvu uye zvinodiwa zvemhando yezvakasarudzwa zvinodzoreredza moto zvinofanirwa kuenderana neyazvino chiyero chenyika "Fireproof Coatings for Steel Structures" (GB14907-2018) uye yazvino chiyero chenyika "Application Technology yeFireproof Coatings for Steel Structures" (CECS24). -2020).

Iyo welding seam yemhando yekuongorora yemafuremu emuchadenga inofanirwa kusangana nezvinodiwa zvechipiri zvinotsanangurwa mu <> (GB50205-2020).Hunhu hwemhando yeweld huchaenderana neyazvino chiyero chenyika "Code for Welding of Steel Structures" GB 50661 Nzira yekuongorora ichaenderana neyazvino chiyero chenyika "Code for Acceptance of Construction Quality of Steel Structure Engineering" GB 50205. For butt. welds ane ukobvu husingasviki 6mm, ultrasonic flaw yekuona haizoshandiswe kuona weld quality giredhi.6.Kana pombi yesimbi nendiro yekuvharisa nemusoro wekoni zvikaita tsvimbo, magaro anosonerera kumigumo yese anenge akazara ekupinda mukati.
