Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
1. Pfungwa ye welding process qualification
Welding process qualification ndiyo yekutanga gadziriro yebasa rese rewelding. Iyo welding maitiro ekufanirwa basa ndeyeyedzo maitiro uye mhedzisiro yekuongorora inoitwa kuti ione kurongeka kwemaitirwo ewelding yeyakatsanangurwa weldment uye zvine hukama zvigadzirwa.
Inosanganisira maitiro e pre-welding kugadzirira, welding, kuyedza uye kuongororwa kwemhedzisiro. Welding maitiro qualification zvakare akakosha maitiro mukugadzira maitiro. Iyi nzira ine chirevo, chinangwa, mhedzisiro, uye chiyero chakaganhurirwa. Naizvozvo, iyo welding process qualification inofanirwa kunge yakavakirwa pane yakarongwa welding process plan, kusanganisira pre-welding gadziriro, welding test zvidimbu, inspection test zvidimbu, uye kuona kana majoini akasungwa ezvimedu zvebvunzo ane akasiyana ehunyanzvi zviratidzo zvekuita kunodiwa. Chekupedzisira, iyo yakaunganidzwa chiitiko chese muitiro Akasiyana-siyana welding process zvinhu, welding data uye bvunzo mhinduro zvinounganidzwa kuita inogutsa uye inokurudzirwa ruzivo rwekugadzira "welding process assessment report".
2. Kukosha kwekufanirwa kwewelding process
Welding maitiro ekuongorora chinhu chakakosha chinongedzo mukuona iwo welding mhando yemaboilers, midziyo yekumanikidza uye pombi dzekumanikidza. Welding process assessment chinhu chakakosha uye chakakosha zvemukati muhunyanzvi hwekugadzirira basa risati raputirwa nemaboilers, midziyo yekumanikidza uye mapaipi ekumanikidza. Icho chinhu chinofanirwa-kuongorora chinhu mukuongororwa kweinjiniya kunoitwa neiyo yenyika mhando uye tekinoroji yekutarisa agency. Izvo zvinofanirwa-kuva nechokwadi chekuti welding process ndeyechokwadi uye inonzwisisika. Iyo nzira ivimbiso yakakosha yekuvimbisa kunaka kwezvikamu zvakashongedzwa uye kuti zvakasiyana-siyana zvemajoini akaiswa anofanirwa kuenderana nechigadzirwa chehunyanzvi mamiriro uye zvinoenderana nezvinodiwa.
Naizvozvo, iko kurongeka uye kurongeka kweiyo welding process kunofanirwa kusimbiswa kuburikidza nekuyedza kunoenderana, ndiko kuti, welding process qualification. Welding process qualification inogona zvakare kuvandudza welding kugadzirwa zvakanaka uye kuderedza mutengo wekugadzira uchiona mhando yemajoini akaiswa, uye kuwana Makuru mabhenefiti ehupfumi.
3. Chinangwa welding process qualification
1 igwaro rehunyanzvi rinofanirwa kuteverwa mukugadzira, kuisirwa, kugadzirisa uye mamwe maitiro ekugadzira mabhailers, midziyo yekumanikidza, pombi dzekumanikidza uye michina, pamwe nekudzidziswa kwewelder uye kudzidzisa.
2 chinhu chakakosha chinongedzo kana chiyero chakakosha chinofanira kuitwa mukukwenenzvera kunaka manejimendi.
3 chiratidzo chakakosha chinoratidza kugona kwekushongedza uye tekinoroji level yeyuniti.
4 Icho chinhu chinofanirwa-kuita-chinotsanangurwa neindasitiri yakakodzera nemitemo yenyika.
4. Chiyero chekushandiswa kwekufanirwa kwewelding process
1 Welding maitiro qualification anoshanda kune welding basa rekugadzira, kuisirwa uye kugadzirisa kwemidziyo yesimbi senge boilers, mapaipi, midziyo yekumanikidza uye inotakura-inotakura simbi zvimiro, pamwe nekudzidzira welder uye welder technical assessment. Welding maitiro qualification inofanira kuitwa isati yaitwa mabasa aya. kuona kurongeka kweiyo yakarongwa welding process.
2 Welding process qualification inoshanda kune welding nzira dzakadai se electrode arc welding, tungsten arc welding, gasi simbi arc welding, flux-cored waya arc welding, gasi welding, uye yakadzika arc welding.
3 Mabhizinesi anoita basa rekugadzira, kuisa kana kugadzirisa.
4 Iyo welding process qualification yakanangwa, uye tekinoroji mamiriro ezvigadzirwa zvakasiyana zvakasiyana. Kana chigadzirwa chiri chikepe chekumanikidza, mhedzisiro yekuyedzwa kweiyo process qualification inofanira kusangana nezvinodiwa zvetekinoroji mamiriro eiyo yekumanikidza mudziyo; kana chigadzirwa chiri chinotakura-inotakura simbi chimiro, maitiro ekukodzera bvunzo mhinduro dzinofanirwa kusangana nezvinodiwa zvehunyanzvi mamiriro eiyo inotakura-inotakura simbi chimiro, nezvimwewo. chekutanga chinodiwa chewelding process qualification test qualification standard.
5. Hunhu welding process qualification
1 Welding process qualification ndeyekugadzirisa welding process matambudziko echero simbi pasi pemamiriro chaiwo, pane kusarudza akanakisa maitiro paramita. Iine humwe huwandu uye inogamuchirwa nevanhu vazhinji.
2 Welding process evaluation ndeyekugadzirisa matambudziko ekuita pasi pemamiriro ezvinhu chaiwo, asi haigone kugadzirisa matambudziko ese emhando inosanganisirwa mukubvisa kushushikana, kudzikisa deformation, kudzivirira kukanganisa kwewelding, nezvimwe.
3. Iyo welding process yekuongorora inofanirwa kuenderana newelding kuita kweiyo mbishi uye kutungamira kugadzirwa kuburikidza neakavimbika tekinoroji mamiriro ebvunzo yewelding process yekuongorora, kudzivirira kushata kwekushandisa zvigadzirwa chaizvo sezvimedu zvebvunzo.
4 Zvinhu zvevanhu zvinofanirwa kubviswa panguva yewelding maitiro ekufanirwa bvunzo maitiro, uye welding maitiro ekufanirwa uye welder hunyanzvi hunyanzvi haufanirwe kuvhiringika. Munhu anoona nezve kukwenenzverwa kwewelding anofanira kunge achikwanisa kusiyanisa kana chikonzero chekukanganisa idambudziko rewelding process kana dambudziko rehunyanzvi hwewelder. Kana iri dambudziko reunyanzvi, rinofanira kugadziriswa kuburikidza nekudzidzira welder.
5 Iwo maedzo anodiwa nearipo welding maitiro ekufanirwa mirau anonyanya kujaira tembiricha yekuyedza majoini akasungwa. Ndokunge, kana yakapfuura chitarisiko chekutarisa, isingaparadze kuyedzwa uye yakajairika tembiricha yemechani bvunzo, inowanzoonekwa seyakapfuura welding process bvunzo. Kune mhando itsva dzesimbi dzepamusoro-tembiricha uye yakakwirira-kudzvanywa mapaipi muindasitiri yemagetsi, mhedzisiro iyi haina kuvimbika zvachose, uye yakakwirira-tembiricha yekutsungirira bvunzo, creep test, kusagadzikana ngura uye kumwe kuedzwa kwemajoini kunofanirwawo kutariswa.
