I-JQ.MH1Cr24Ni13 insimbi yokushisela yensimbi engagqwali ngaphansi kwamanzi

JQ.MH1Cr24Ni13 stainless steel submerged-arc welding wire Featured Image

Ivamise ukusetshenziswa ekushiseleni i-carbon steel nensimbi engagqwali izinto ezingafani noma ekushiseleni izinsimbi ezingenasici ze-martensitic kanye ne-pearlitic ezinokuqina okubi.Izicelo ezifana ne-petrochemical, izitshalo zamandla ashisayo nezinye izimboni.

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.
