(1) Cov ntaub ntawv raw yog sawb coil, vuam hlau thiab flux. Lawv yuav tsum tau kuaj xyuas lub cev thiab tshuaj nruj ua ntej muab tso rau hauv kev siv.
(2) Lub taub hau thiab tus Tsov tus tw ntawm lub sawb hlau yog butted los ntawm ib lub xaim lossis ob lub xaim submerged arc vuam, thiab tsis siv neeg submerged arc vuam yog siv los kho vuam tom qab dov rau hauv cov yeeb nkab steel.
(3) Ua ntej kev tsim, lub sawb yog leveled, trimmed, npaj, deg ntxuav thiab conveyed thiab pre-bending.
(4) Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej ntawm ob sab ntawm cov khoom siv los xyuas kom meej qhov kev sib tw ntawm cov sawb.
(5) Txais kev tswj sab nraud lossis kev tswj sab hauv yob txoj kev.
(6) Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld ua tau raws li qhov xav tau ntawm vuam, thiab cov yeeb nkab txoj kab uas hla, tus nqi ntawm misalignment thiab qhov sib txawv weld yog nruj me ntsis tswj.
(7) Ob leeg welding sab hauv thiab sab nraud welding siv American Lincoln vuam tshuab rau ib leeg-xaim los yog ob-xaim submerged arc vuam, thiaj li kom tau txais kev ruaj khov vuam specifications.
(8) Cov welded seams yog txhua yam tshuaj xyuas los ntawm online nruam ultrasonic tsis siv neeg qhov tsis zoo tester, uas ua kom 100 feem pua tsis muaj kev puas tsuaj rau kev ntsuas ntawm cov kauv welds. Yog tias muaj qhov tsis xws luag, nws yuav cia li ceeb toom thiab tshuaj tsuag lub cim, thiab cov neeg ua haujlwm tsim khoom tuaj yeem kho cov txheej txheem tsis raug txhua lub sijhawm raws li kev tshem tawm qhov tsis xws luag hauv lub sijhawm.
(9) Siv lub tshuab cua plasma txiav cov yeeb nkab steel rau hauv ib daim.
(10) Tom qab txiav rau hauv ib lub yeeb nkab steel, txhua batch ntawm peb lub taub hau steel yeeb nkab yuav tsum tau ua raws li kev tshuaj xyuas thawj zaug los xyuas cov khoom siv tshuaj lom neeg, tshuaj lom neeg muaj pes tsawg leeg, kev sib xyaw ua ke ntawm cov vuam, qhov zoo ntawm cov yeeb nkab steel thiab tsis yog. kev kuaj kev puas tsuaj los xyuas kom meej cov yeeb nkab ua cov txheej txheem. Tsuas yog tom qab dhau qhov kev xeem tuaj yeem muab tso rau hauv kev tsim khoom.
(11) Cov khoom uas muaj qhov tsis txaus ntseeg nrhiav pom cov cim ntawm cov welds yuav tsum rov kuaj xyuas los ntawm phau ntawv ultrasonic yoj thiab X-ray. Yog tias lawv muaj kev puas tsuaj tiag tiag, tom qab kho, lawv yuav tsum tau kuaj xyuas tsis muaj kev puas tsuaj ntxiv mus txog thaum nws tau lees paub tias qhov tsis xws luag raug tshem tawm. 8 plus H! e" l' v/ U. t
(12) Lub raj uas lub pob tw welding seam thiab T-joint sib tshuam nrog cov kauv vuam seam nyob yuav tsum tau soj ntsuam los ntawm X-ray TV lossis ua yeeb yaj kiab. / ^3 U1 E% |. ]; M: F&r
(13) Txhua lub yeeb nkab steel yog kuaj los ntawm hydrostatic siab, thiab lub siab yog radially kaw. Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm cov yeeb nkab steel dej siab microcomputer nrhiav kom tau cov cuab yeej. Cov ntsuas ntsuas tau raug luam tawm thiab kaw. " h/ R* F3 ]9 x- n
(14) Cov yeeb nkab kawg yog machined, thiaj li hais tias lub verticality ntawm lub ntsej muag kawg, lub bevel lub kaum sab xis thiab blunt ntug yog tswj kom raug.
