I-JQ.MH00Cr24Ni13 insimbi yokushisela yensimbi engaphansi emanzini

JQ.MH00Cr24Ni13 stainless steel submerged-arc welding wire Featured Image

Ivamise ukusetshenziswa ekushiseleni i-carbon steel nensimbi engagqwali izinto ezingafani, embonini ye-petrochemical efana nokuvela kwezinsimbi eziguqukayo odongeni lwangaphakathi lomkhumbi wokusabela, noma ekushiseleni izinsimbi ezingenasici ze-martensitic neze-ferritic ezinokuqina okubi, kanye nokushiselwa kwezinto ezifanayo.

Izici

Uma kuqhathaniswa ne-welding manual, isivinini sokubeka singakhuphuka izikhathi ezingu-2-4, kanti ukusebenza kahle kwe-deposition kuphezulu njengo-90%.

Ukuguquguquka kwamanje kanye ne-voltage kukhulu, ukumiswa kwezimo zokushisela kulula, futhi kulula ukwenza i-semi-automatic kanye ne-othomathikhi.

Ukususwa okuhle kwe-slag kanye nobuhlalu obucwebezelayo be-weld.Ngaphezu kwalokho, kukhona ukuchaphaza okuncane, ukuzinza kwe-arc kuhle kakhulu, futhi i-X-ray ifanelekile.

Izinyathelo zokuphepha zokusetshenziswa komkhiqizo

1.Izinga lokushisa phakathi kwama-welds liyanconywa ukuthi lilawulwe cishe ku-150°C.Lapho i-multi-pass multi-layer welding ye-specification encane naphakathi, qaphela ukulawula amandla we-welding line.
2.Isendlalelo sokugqwala, umswakama, uwoyela, uthuli, njll. yengxenye yokushisela kufanele ihlanzwe.
3.I-flux kufanele ibhakwe ku-300-350 ℃ amahora angu-2 ngaphambi kokusetshenziswa.
Iziphakamiso ezingenhla ngezereferensi kuphela, futhi isimo sangempela siyoba khona emsebenzini othize.Uma kunesidingo, ukufaneleka kwenqubo kufanele kwenziwe ngaphambi kokunquma uhlelo lwe-welding.
