2.Isendlalelo sokugqwala, umswakama, uwoyela, uthuli, njll. yengxenye yokushisela kufanele ihlanzwe.

3.I-flux kufanele ibhakwe ku-300-350 ℃ amahora angu-2 ngaphambi kokusetshenziswa.

Isicelo

Isetshenziswa kakhulu ku-petrochemical nezinye izimboni, ezifana nokushisela i-022Cr18Ni9 (SUS 304L) nezinye izinto.

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.
