Umgangatho we weld yombhobho wentsimbi yomthungo othe tye (lsaw/erw):

Ngenxa yempembelelo ye-welding current kunye nefuthe lomxhuzulane, i-weld yangaphakathi yombhobho iya kuphuma, kwaye i-weld yangaphandle iya kugoba. Ukuba ezi ngxaki zisetyenziswa kwindawo eqhelekileyo yoxinzelelo oluphantsi loxinzelelo, aziyi kuchaphazeleka.

Ukuba isetyenziswe kwiqondo lokushisa eliphezulu, uxinzelelo oluphezulu kunye nesantya esiphezulu sendalo yamanzi, kuya kubangela iingxaki ekusebenziseni. Esi siphene kufuneka sipheliswe kusetyenziswa izixhobo ezizinikeleyo zokulinganisa i-weld.

Umgaqo osebenzayo wesixhobo sokulinganisa i-welding seam yile: i-mandrel enobubanzi obuyi-0.20mm encinci kune-diameter yangaphakathi yombhobho ibekwe kumbhobho odibeneyo, kwaye i-mandrel idibaniswe kwi-cylinder ngentambo yocingo. Ngokusebenzisa i-cylinder yomoya, i-mandrel inokuhanjiswa ngaphakathi kwendawo ehleliweyo. Ngaphakathi ubude mandrel, iseti imiqulu phezulu nasezantsi zisetyenziselwa ukuqengqeleka weld kwi isindululo reciprocating perpendicular kwindawo weld. Ngaphantsi koxinzelelo lwe-mandrel kunye ne-roll, i-protrusions kunye ne-depressions iyapheliswa, kwaye i-contour ye-weld kunye ne-pipe contour iguqulwa ngokufanelekileyo. Ngexesha elifanayo kunye nokunyangwa kwe-welding leveling, isakhiwo sengqolowa enqabileyo ngaphakathi kwe-weld siya kuxinzelelwa, kwaye siya kudlala indima ekuphuculeni ubuninzi besakhiwo se-weld kunye nokuphucula amandla.

Intshayelelo yomgangatho we-weld:

Ngethuba lenkqubo yokugoba yomgca wensimbi, ukuqina komsebenzi kuya kwenzeka, okungahambi kakuhle kwi-post-processing yombhobho, ngokukodwa ukugoba kombhobho.
Ngethuba lenkqubo ye-welding, i-coarse grain structure iya kuveliswa kwi-weld, kwaye kuya kubakho uxinzelelo lwe-welding kwi-weld, ngakumbi ekudibaneni phakathi kwe-weld kunye nesiseko sesinyithi. . Izixhobo zokunyanga ubushushu ziyafuneka ukuze kupheliswe ukuqina komsebenzi kunye nokucokisa ukwakhiwa kweenkozo.
Okwangoku, inkqubo yonyango yokushisa esetyenziswa ngokuqhelekileyo yindlela eqaqambileyo yonyango kwi-hydrogen yokukhusela umoya, kwaye umbhobho wensimbi engenasici ufudumala ukuya kwi-1050 °.
Emva kwexesha lokugcinwa kobushushu, ulwakhiwo lwangaphakathi lutshintsha ukwenza i-uniform austenite structure, engenzi oxidize phantsi kokukhuselwa kwe-hydrogen emoyeni.
Isixhobo esisetyenzisiweyo sisisombululo esikhanyayo kwi-intanethi (i-annealing) izixhobo. Isixhobo sidityaniswe neyunithi yokwenza i-roll-bending, kwaye umbhobho odibeneyo uphantsi konyango lwesisombululo esikhanyayo kwi-intanethi ngexesha elifanayo. Isixhobo sokufudumeza samkela i-frequency ephakathi okanye unikezelo lwamandla ombane aphezulu ukufudumeza ngokukhawuleza.
Yazisa i-hydrogen ecocekileyo okanye umoya we-hydrogen-nitrogen ukukhusela. Ubunzima bombhobho odibeneyo bulawulwa kwi-180±20HV, enokuthi ihlangabezane neemfuno ze-post-processing nokusetyenziswa.
