Muzviitiko zvakawanda, pfuti dzeMIG dzinoshandiswa dzinogona kunge dziri dzekupedzisira mukugadzirisa kwekugadzira, sekunetsekana nemidziyo, kufambiswa kwebasa, dhizaini yechikamu uye zvimwe zvinotonga kutarisisa kwevashandisi vewelding, vatariri nevamwe vanobatanidzwa mukushanda. Asi, izvi zvikamu - kunyanya matipi ekuonana - anogona kuve nemhedzisiro yakakura pakuita welding.
Mune yeMIG welding process, iyo yekubata tipi ine basa rekuendesa iyo welding ikozvino kune waya iyo ichipfuura nemubore, ichigadzira arc. Zvakakwana, waya inofanira kudya kuburikidza nekushomeka kushoma uchiri kuchengetedza magetsi. Nzvimbo yetipi yekubata mukati memuromo, inodaidzwa seyekusangana tip recess, yakakoshawo. Inogona kupesvedzera kunaka, kugadzirwa uye mutengo mukushanda kwewelding. Zvinogonawo kukanganisa huwandu hwenguva inopedzwa kuita zviitwa zvisina-awedzero, senge kukuya kana kuputika zvikamu zvisingabatsire mukubuda kwese kwese kana pundutso.
Iyo chaiyo yekubata tipi recess inosiyana zvichienderana nekushandisa. Nekuti waya shoma inonamira kazhinji inokonzeresa arc yakagadzikana uye nani yakaderera-voltage kupinda, iyo yakanakisa waya yekunamira kureba ndiyo ipfupi inotenderwa kushandiswa.
Mhedzisiro pamhando ye weld
Kubata tip recess kunokanganisa akati wandei zvinhu izvo zvinozogona kukanganisa weld mhando. Semuyenzaniso, kunamira kana electrode yekuwedzera (kureba kwewaya pakati pekupedzisira kwetipi yekubata uye nzvimbo yebasa) inosiyana zvichienderana nekubata tip recess - kunyanya, iyo yakakura yekubata tipi recess, iyo yakareba waya inonamira. Sezvo waya yekunamatira inowedzera, voltage inowedzera uye amperage inoderera. Kana izvi zvikaitika, iyo arc inogona kudzikamisa, ichikonzera yakawandisa spatter, arc kudzungaira, kushomeka kwekudzora kupisa pasimbi dzakatetepa uye kunonoka kufamba kumhanya.
Bata tip recess zvakare inokanganisa kupisa kunopenya kubva kune welding arc. Heat buildup inotungamira mukuwedzera kwekupokana kwemagetsi kumberi-kumagumo zvinodyiwa, izvo zvinoderedza kugona kwetipi yekupfuura yekupfuura ikozvino kune waya. Izvi zvisina kunaka conductivity zvinogona kukonzera kusakwana kwekupinda, spatter uye mamwe matambudziko anogona kukonzera isingagamuchirwi weld kana kutungamira kune rework.
Zvakare, kupisa kwakanyanya kunowanzo kudzikisa hupenyu hwekushanda hwetipi yekusangana. Mhedzisiro yacho ndeyepamusoro pese mari inodyiwa uye yakanyanya kudzika nguva yekubata tip shanduko. Nekuti kushanda kunenge nguva dzose kuri mutengo mukuru mukushanda kwewelding, iyo nguva yekuzorora inogona kuwedzera kusvika pakuwedzera kusingakoshi mumitengo yekugadzira.
Chimwe chinhu chakakosha chakakanganiswa nekubata tip recess kuchengetedza gasi kufukidzwa. Kana iyo yekubata tipi yekuzorora ichimisa muromo kure kure nearc uye weld puddle, nzvimbo yewelding inotapukirwa nekuyerera kwemhepo inogona kukanganisa kana kudzinga gasi rinodzivirira. Kutadza kudzivirira gasi kufukidzwa kunotungamira kune porosity, spatter uye kusakwana kwekupinda.
Nekuda kwezvikonzero zvese izvi, zvakakosha kuti ushandise iyo chaiyo yekubata recess yekushandisa. Mamwe mazano anotevera.
Mufananidzo 1: Iyo chaiyo yekubata tipi recess inosiyana zvichienderana nekushandisa. Gara uchibvunza kurudziro yemugadziri kuti uone iyo chaiyo yekubata tip recess yebasa.
Mhando dzekusangana tip recess
Iyo diffuser, muromo uye muromo ndiwo zvikamu zvitatu zvekutanga zvinosanganisira MIG pfuti dzinoshandiswa. Iyo diffuser inonamira yakananga kumutsipa wepfuti uye inotakura ikozvino kuburikidza neiyo yekubata tipi uye inotungamira gasi mumuromo. Iyo yemuromo inobatana neye diffuser uye inoendesa ikozvino kune waya sezvainoitungamirira kuburikidza nemuromo uye kune weld puddle. Iyo muromo inonamira kune diffuser uye inoshanda kuchengetedza iyo inodzivirira gasi yakanangana neiyo welding arc uye puddle. Chimwe nechimwe chikamu chinoita basa rakakosha mune yakazara weld mhando.
Mhando mbiri dzekuonana tip recess dziripo neMIG pfuti dzinoshandiswa: yakagadziriswa kana inogadziriswa. Nekuti inogadzirika yekubata tipi recess inogona kuchinjika kune akasiyana siyana ehudzamu uye mawedzero, ivo vane mukana wekukwanisa kuzadzisa zvinodiwa recess yeakasiyana maapplication uye maitiro. Nekudaro, ivo zvakare vanowedzera mukana wekukanganisa kwevanhu, sezvo welding vanoshanda vachiagadzirisa nekufambisa chinzvimbo chemuromo kana kuburikidza nekiyi nzira inochengetedza iyo yekubata tipi pane yakapihwa recess.
Kudzivirira misiyano, mamwe makambani anosarudza yakagadziriswa-recess matipi senzira yekuona weld kufanana uye kuwana mhedzisiro inowirirana kubva kune mumwe welding opareta kune anotevera. Yakagadziriswa recess matipi akajairika mune otomatiki welding maapplication uko inopindirana matipi nzvimbo yakakosha.
Vagadziri vakasiyana-siyana vanogadzira zvinodyiwa kuti zvigone kudzika kwakasiyana-siyana kwekusangana tip recess, izvo zvinowanzobva pa1⁄4-inch recess kusvika 1⁄8-inch yekuwedzera.
Kusarudza recess chaiyo
Iyo chaiyo yekubata tipi recess inosiyana zvichienderana nekushandisa. Mutemo wakanaka wekutarisa uri pasi pemamiriro mazhinji, sezvo ikozvino inowedzera, iyo recess inofanirawo kuwedzera. Zvakare nekuti waya shoma inonamira kazhinji inokonzeresa arc yakagadzikana uye nani yakaderera-voltage kupinda, yakanakisa waya yekunamira kureba ndiyo ipfupi inotenderwa kushandiswa. Heano mamwe mazano, pazasi. Zvakare, ona Mufananidzo 1 kune mamwe manotsi.
1.Nokuda kwe pulsed welding, spray transfer process uye mamwe maapplication anopfuura 200 amps, a contact tip recess ye 1/8 inch kana 1/4 inch inokurudzirwa.
2.Kumashandisirwo ane mafungu akakwirira, akadai seaya anojoinha simbi dzakakora newaya yakakura-dhayamita kana simbi-cored waya ine spray transfer process, recessed contact tip inogonawo kubatsira kuchengetedza muromo wekubata kure nekupisa kwakanyanya kwearc. Kushandisa waya yakareba yekunamatira kune aya maitiro kunobatsira kudzikisa kuitika kwekutsva (apo waya inonyungudika uye inobata kune yekubata tip) uye spatter, iyo inobatsira kuwedzera yekuonana matipi hupenyu uye kuderedza mari inoshandiswa.
3.Paunenge uchishandisa pfupi-circuit yekufambisa maitiro kana yakaderera-ikozvino pulse welding, flush yekubata tipi ine waya yekunamira inosvika 1⁄4 inch inowanzokurudzirwa. Hurefu hupfupi hwekunamira hunobvumira kufambisa-pfupi-kutenderera kune weld zvinhu zvitete pasina njodzi yekutsva-kuburikidza kana kuputika uye ine yakaderera spatter.
4.Mazano akawedzerwa ekukurukura anowanzochengeterwa nhamba shoma shoma yezvikumbiro zvemapfupi ane zvakaoma-kusvika-kusvika-kusvika majoint configurations, zvakadai seyakadzika uye yakamanikana V-groove majoini mupombi welding.
Aya mafungidziro anogona kubatsira nesarudzo, asi gara uchibvunza kurudziro yemugadziri kuti uone iyo chaiyo yekubata tip recess yebasa racho. Rangarira, nzvimbo chaiyo inogona kuderedza mukana wekunyanya spatter, porosity, kusakwana kwekupinda, kupisa-kuburikidza kana kuputika pazvinhu zvitete, nezvimwe. Zvakare, kana kambani ikaona yekuonana tip recess semukonzeri wematambudziko akadai, inogona kubatsira kubvisa zvinotora nguva uye zvinodhura kugadzirisa matambudziko kana post-weld zviitiko senge rework.
Rumwe ruzivo: Sarudza matipi emhando
Nekuti matipi ekuonana chinhu chakakosha pakupedzisa mhando welds uye kuderedza nguva yekudzikira, zvakakosha kuti usarudze yemhando yepamusoro yekubata tip. Nepo zvigadzirwa izvi zvichigona kudhura zvishoma pane zvigadzirwa zvegiredhi-zvishoma, zvinopa kukosha kwenguva refu nekuwedzera hupenyu uye kudzikisa nguva yekuchinja. Pamusoro pezvo, matipi epamusoro-soro ekusangana anogona kugadzirwa kubva kune yakagadziridzwa alloys yemhangura uye anowanzo kugadzirwa kuti awedzere kushivirira kwemagetsi, achigadzira zvirinani kupisa uye magetsi ekubatanidza kudzikisira kupisa uye kuramba kwemagetsi. Zvekushandisa zvemhando yepamusoro zvinogara zvakapfava pakati pepakati, zvichikonzera kukweshana kushoma sezvo waya ichipinda. Izvi zvinoreva kuenderana kudyisa waya nekukweva kushoma, uye mashoma anogona kuitika emhando nyaya. Mazano epamusoro-soro ekuonana anogonawo kubatsira kuderedza kupisa uye kubatsira kudzivirira arc inokanganisa inokonzerwa nekusawirirana kwemagetsi.
