Ulwahlulo lwe-BS EN 10219

NgoHlobo Lwentsimbi

Iintsimbi ezikhethekileyo ezingafakwanga kunye nezidibeneyo.

Iintsimbi ezingalukwanga:

S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, S355K2H,S275NH, S275NLH, S355NH, S355NLH.

Iintsimbi ezidityanisiweyo ezikhethekileyo:

S460NH, S460NLH, S275MH, S275MLH, S355MH, S355MLH, S420MH, S420MLH, S460MH, S460MLH.

Indlela elula yokuxelela umahluko: iintlobo zetsimbi eziqukethe i-M okanye i-4 ziyi-alloys, kunye neempawu ze-alloying zensimbi zinokuqatshelwa ngokukhawuleza.

NgeNkqubo yokuVelisa

Iinkqubo zemveliso ezisetyenziselwa ukwenza imibhobho yentsimbi ngokwe-BS EN 10219 ibandakanyaI-Welding Resistance Welding (ERW) kunye ne-Summerged Arc Welding (SAW).

I-SAW ingahlelwa ngakumbi kwi-Longitudinal Submerged Arc Welding (LSAW) kunye ne-Spiral Submerged Arc Welding (SSAW) ngokusekwe kuhlobo lwe-weld seam.

NgokweMilo enqamlezileyo

CFCHS: Ingqele eyenziwe yamacandelo avulekileyo ajikelezayo;

I-CFRHS: Indawo ebandayo eyenziwe isikweri okanye uxande;

I-CFEHS: Amacandelo akwimigongxo abandayo;

Eli phepha ligxininisa kwi-CFCHS (iCandelo eliQhelekileyo eliyiSetyhula eliHollow).
