1. Rekodhi rekutanga regirazi welding
Mirror welding ndeye welding operation tekinoroji yakavakirwa pamusimboti wegirazi yekufungidzira uye inoshandisa girazi-inobatsirwa kutarisa kudzora maitirwo ekuita welding. Inonyanya kushandiswa pakugadzira welds iyo isingagoni kutariswa zvakananga nekuda kwenzvimbo yakamanikana welding.
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)
Nzvimbo yakagadziriswa yegirazi kazhinji ine zvinodiwa zviviri. Kutanga, inofanira kunge yakanakira kuti ziso rakashama rione mamiriro edziva rakanyungudutswa kuburikidza nekuratidzira kwegirazi. Chechipiri, haifaniri kukanganisa nzvimbo ye argon arc welding gun uye kufamba uye kuzununguka kwepfuti yekuputika panguva yekugadzira. Nharaunda pakati pegirazi uye weld seam Nzvimbo inowirirana yemitsara yechubhu inogadziriswa zvichienderana nekuparadzaniswa.
2. Kugadzirira kusati kwaita welding
(1) Nzvimbo yewelding gap inofanira kunyatsodzorwa, kazhinji 2.5 ~ 3.0 mm. Nzvimbo yekushongedza seam chinzvimbo inofanira kunge iri pamberi pepombi.
(2) Kuiswa kwelenzi: Isa lens munzvimbo inotangisa nemoto, uye shandisa pfuti yewelding kutevedzera trajectory panguva yewelding kugadzirisa chinhambwe uye kona yelens kuitira kuti lens ive panzvimbo yakanyanya kunaka. welding kuona.
(3) Tarisa kuti argon gasi inoyerera yakawanda 8 ~ 9 L/min, iyo tungsten electrode yekuwedzera kureba i3 ~ 4 mm, uye arc curvature yewaya yewelding yakafanogadzirirwa.
3. Kuongororwa kwezvinetso mugirazi welding
(1) Mirror imaging is reflection imaging. Panguva yekushanda kwemoto, kushanda kunoonekwa neanopisa mu radial direction yemuromo wepombi kunopesana negwara chairo. Munguva yekugadzira welding, zviri nyore kudyisa waya kune dziva rakanyungudutswa mugirazi. , zvichikanganisa normal welding.
Naizvozvo, kuzungunuka kweiyo welding arc uye kufambisa-kuzadza waya kwakaoma kuve kwakabatana, kuenderana, uye kurongeka, izvo zvinogona kuita nyore kuti arc ive yakarebesa, tungsten kudzvanywa, waya-kuzadza kusakwana, uye. kupera kwewaya yewelding kudhumhana netungsten electrode.
(2) Iyo lateral swing uye kufamba kweiyo welding arc haina kuchinjika zvakakwana, izvo zvinogona kutungamira kune isina kukwana kupinda mukati memudzi, concavity, kushaikwa kwefusion, undercutting, uye kutadza kuumbwa. Kana iyo yekumhanyisa kumhanya ichinonoka, kuremara senge pores kunogona kuitika nyore.
(3) Kana uchitarisa dziva rakanyungudutswa nepagirazi, arc light reflection yakasimba uye zvakaoma kuona tungsten tsvimbo zvakajeka. Paunenge uchidyisa waya, zviri nyore kuita kuti tambo yewelding irove netsvimbo yetungsten, kukanganisa muromo wetungsten tsvimbo, inokanganisa kugadzikana kwearc, uye kukonzeresa nyore kukanganisa senge tungsten kuiswa. .
(4) Musono we weld unoonekwa nepagirazi mufananidzo wakatsetseka. Iko-matatu-dimensional maitiro eiyo weld seam mugirazi haina kusimba, uye magirazi emifananidzo yearc mwenje uye dziva rakanyungudutswa rakaiswa pamusoro peumwe neumwe. Chiedza chearc chakanyanya kusimba, uye zvakaoma kusiyanisa zvakajeka dziva rakanyungudutswa, saka weld seam Kudzora kwehupamhi uye kutwasuka kunozokanganisa zvakananga kunaka kwekugadzira seam kugadzirwa.
4. Mirror welding operation nzira
(1) Base layer welding
a.Inner wire nzira
Isa pfuti yemoto munzvimbo iyo welding inotanga kurova arc, uye kutakura tambo yewelding kuburikidza negororo regorovha kumberi kune arc inopisa nzvimbo kumashure. Tarisa kuumbwa kwemudzi neziso rakashama, uye zvakare tarisa kupisa kwearc uye kutaridzika kuumba mulenzi nguva nenguva. . Shandisa "mbiri inononoka uye imwe inokurumidza" nzira yekushandisa pfuti yewelding.
Dzora ukobvu hwebhesi layer pa2.5 ~ 3.0 mm. Weld kubva 6 o'clock kusvika 9 o'clock, uye ipapo weld kubva 6 o'clock kusvika 3 o'clock. Pedzisa base layer welding zvinoenderana nekutevedzana kunoratidzwa mumufananidzo 2.
b.Ekunze sirika nzira
Kutanga, gadzirirai arc yehuwandu hwewaya yekubatira, wozogadzirisa muromo wepfuti welding pane pombi weld bead pakona ye60 °, tanga arc, uye teerera kune waya yekudyisa mamiriro earc uye dziva rakanyungudutswa. mu lenzi.
Waya inogona kudyiswa nguva dzose kana nekukanganiswa kwearc. Kuratidzira kwe lens kunogona kutsausa kushanda nyore nyore: semuenzaniso, zvakaoma kusiyanisa pakati peiyo chaiyo welding waya uye welding waya inoratidzwa mulens, izvo zvinogona kutungamira kune kusakwana kwekudya kwewaya, yakanyanya kunyungudutswa dziva tembiricha, uye kukuvara iyo tungsten. Kunyanya, kuremara senge pores uye depressions kunoonekwa.
Naizvozvo, oparesheni ndeyekuzvipira kune kuratidzwa kwegirazi, uye nekuziva hokoka iyo arc curvature yewaya yewelding mugororo kuti udyise waya zvakaenzana. Pfuti yekuputika inoshandiswa uchishandisa nzira ye "mbiri inononoka uye imwe inokurumidza", uye kona yepfuti yemoto inogadziriswa maererano nearc mu lens.
Dzivisa kurerekera pfuti yewelding zvakanyanya, zvichiita kuti arc ive yakarebesa uye chigadziko chive chakakora, kudzivirira kukanganisa kwakadai sekupinzwa kusina kukwana. Kana welding iri pakati pe8 o'clock uye 9 o'clock, chikamu chearc chaiyo inogona kuonekwa, uye kushanda kunogona kusanganiswa nemamiriro chaiwo uye girazi pamusoro.
Pedzisa 1/4 yepombi muromo weld uye wotanga girazi welding yeimwe 1/4 ye weld. Kubatana pa6 o'clock chinzvimbo ndechimwe chekushanda kwakakosha kwegirazi welding, uye kukanganisa kunowanzoitika panguva yekudzokera kumashure.
Panguva yekushanda, kuve nechokwadi chemhando yejoint, iyo arc inofanira kupiswa paanenge 8 ~ 10 mm yepamberi weld yejoint, uye ipapo arc inofanira kuunzwa zvakatsiga kujojo yekumberi weld pa6 o'clock. . Kana dziva rakanyungudutswa raumbwa pajoini Wobva wawedzera waya yewelding kuti ishandiswe negirazi remoto.
Pakupedzisira, zadzisa iyo yekutanga welding kudivi remberi (isina-mirror welding) zvinoenderana nekutevedzana kuri mumufananidzo 2, uye kuiswa chisimbiso kwapera.
(2) Cover layer welding
1) Kuomerwa kuongorora
Nemhaka yokuti nzvimbo ye weld mugirazi inopesana neiyo yechinhu chaicho, zviri nyore kukonzera undercuts, unfused edges of grooves, unfused internal layers, pores, kana kukanganisa kwe tungsten electrode panguva yekushanda.
2) Kuvhara welding kushanda zvinodiwa
Pamberi pekuputira, nzira yepfuti yewelding inofanira kufananidzwa, uye kona ye lens uye arc curvature yehuwandu hwakagadzirirwa hwetambo yewelding inofanira kugadziriswa.
Panguva yekushanda kwewelding, iwe unofanira kutanga wagadzirisa muromo wepfuti yemoto panzvimbo ye6 o'clock ye groove pakona ye60 ° ye arc preheating. Mushure mekupisa, nekupenya kwearc mwenje, wedzera iyo pre-curved welding wire kubva parutivi rwepombi kusvika kune arc inopisa point mulens. Position, feed wire. Nzira yakanakisa yekudyisa waya ndeyekukochekera waya welding nearc curvature kune welding seam yepombi, zvishoma nezvishoma kudyisa waya ichienderera uye yakaenzana mudziva rakanyungudutswa, uye tarisa kukura kwemupendero we welding seam uye shanduko ye. madonhwe akanyunguduka ari mulenzi. maitiro uye kureba kwearc ye tungsten electrode tip,
Zvinoenderana ne "mbiri inononoka uye imwe inokurumidza" welding nzira, famba uchienda kunzvimbo ye9 o'clock mugirazi pamusoro kuti upedze 1/4 yekuvhara pamusoro welding uye kudzima arc. Wobva wafambisa lens kune imwe 1/4 yekumashure weld ye trajectory simulation kugadzirisa uye kugadzirisa. Kusashanda zvakanaka kweiyo interface pa6 mapoinzi kunozokonzeresa kuremara kwewelding, uye iri dense chikamu uko hurema hunoitika.
Zviri nani kutanga kupisa arc kumberi weld na6 o'clock. Kana iyo joint yanyunguduka ikava dziva rakanyungudutswa, wedzera waya welding kuti uite zvakajairika girazi welding operation. Chenjerera kumamiriro ekunyunguduka kwemupendero uye tevera nzira yekutanga 1/4. Shanda kusvikira arc yabuda na3 o'clock uye yamira.
Zvadaro weld chikamu chiri welded maererano dzakajairwa nzira kupedzisa chivharo layer welding yepombi yose.
5. Chengetedzo
①Unyanzvi hwekuisa girazi hwakakosha. Iyo iyo lens iri kure kubva kuchinhu chaicho kana kuti kuderera kudiki kunoenderana nechinhu chaicho, iyo yakanyanya kurongeka kwekushanda kuchave;
②Kure kure kwelenzi uye chinhu kubva kumushandisi, ndiko kunonyanya kuoma kushanda kwacho;
③ Mukaha uripo pakati pezvikamu zviviri unofanira kunyatsodzorwa, kona yepfuti yemoto inofanira kunge yakakodzera, welding inofanira kunge yakarongeka, uye kunzwa kwekuwedzera waya mugirazi kunofanira kujeka.
