Kungodiwa chete pamusoro peimwe layer, inogona kusangana nekupokana kwekuora kwe weld tepi

Shongwe inoshandiswa kuita distillation, kucheneswa, kunyudza, distillation uye mamwe makemikari emidziyo, mazhinji eshongwe maturusi anofanirwa kubata acid, alkali, munyu, organic solvents uye imwe corrosive media, saka zvinodikanwa kuti utarise nzvimbo yakakura yecorrosion resistant layer. muhumburumbira uye zvikamu zvekuisa chisimbiso. Senzira inoshanda yekutarisa, strip sufacing inoshandiswa zvakanyanya mushongwe welding yemakemikari michina.
Iyo yechinyakare electrode sufacing tekinoroji ndeye kaviri-layer yakanyudzwa arc yakatarisana tekinoroji ine shanduko layer uye corrosion resistant layer, asi tekinoroji iyi ine nguva yakareba yekugadzira uye mutengo wakakwira wekugadzira. Kuti igadzirise dambudziko iri, JingQunCo yakagadzira-single-layer surfacing welding materials (GDS-309LA welding strip, GXS-ED308L electroslag flux), iyo inokwanisa kuzadzisa mhedzisiro ye-two-layer kutariswa nekungomira-layer pamusoro, uye inogona kurerutsa. iyo yekumusoro maitiro kubva kune maviri-layer kumusoro kune imwe-layer kumusoro.

Weld pass ukobvu: anenge 4.7mm

Weld hupamhi: anenge 62.5mm

Weld pass chitarisiko: yakanaka chimiro, weld surface iri flat, lap shanduko yakatsetseka.

3.Mechanical kugona

Ferrite yemukati (welded state)

Solder strip + Flux musanganiswa	GDS-309LA+GXS-ED308L
Kuyerwa kukosha	Iyo ferrite yemukati inenge 7FN, uye iyo ferrite muzana yemukati inenge 8%
Kuyera nzvimbo	Weld pamusoro

Muedzo nzira: GB/T 1954-2008 "chromium-nickel austenitic Stainless simbi weld ferrite zvemukati kuyerwa nzira"
