Metallurgical properties yezvinhu

Longitudinal yakanyura arc welded pombi inogadzirwa kubva kumarata esimbi, nepo spiral welded pombi inogadzirwa kubva kune inopisa-yakakungurutswa makoiri.Iyo inopisa-yakakungurutswa strip unit rolling process ine akawanda mabhenefiti uye ine metallurgical process kugona kuwana kugadzirwa kwemhando yepamusoro pombi mutsetse simbi.Semuyenzaniso, chinobuda chigadziko chakashongedzerwa nemvura inotonhora sisitimu kuti ikurumidze kutonhora, iyo inobvumira kushandiswa kweyepasi-alloy nziyo kuti iwane yakakosha magiredhi esimba uye yakaderera-tembiricha kuoma, nekudaro kuvandudza weldability yesimbi.Nekudaro, iyi sisitimu haisipo zvakanyanya mumashizha ekugadzira simbi.Iyo alloy yemukati (kabhoni yakaenzana) yemakoiri kazhinji yakadzikira pane iyo yemagiredhi akafanana emarata esimbi, ayo anovandudzawo weldability yepiral welded pombi.

Chinonyanya kukosha kucherechedzwa ndechekuti, nekuti iyo spiral welded pombi coil rolling direction haina perpendicular kugwara resimbi pombi axis (pinch solution inoenderana nespiral angle yepombi yesimbi), ukuwo simbi yakatwasuka simbi pombi inokunguruka. direction perpendicular to the direction of simbi pombi axis, uye nokudaro, spiral welded pombi zvinhu zviri nani pane yakatwasuka musono simbi pombi kuparuka kuramba.

Welding Process

Kubva pakugadzira dhizaini, spiral welded pombi uye yakatwasuka musono simbi pombi welding nzira yakangofanana, asi iyo yakatwasuka musono welded pombi ichange iine yakawanda ding weld, saka mikana yekuremara kwewelding inowedzera zvakanyanya, uye kusara kwekunetseka kwewelding. pa ding weld yakakura, iyo weld simbi kazhinji iri mutatu-nzira yekushushikana mamiriro, ichiwedzera mukana wekutsemuka.

Uyezve, maererano neyakanyura arc welding process, weld yega yega inofanirwa kunge iri paarc yekutanga uye arc kudzimisa, asi imwe neimwe yakatwasuka seam yakasungwa pombi mune yakashongedzerwa annular seam, haigone kuzadzisa mamiriro acho, nekudaro panogona kunge paine hurema hwakanyanya paarc. kudzima.
