Kana welding, chinangwa ndechekugadzira chisungo chakasimba, chisina musono pakati pezvidimbu zviviri zvesimbi.MIG welding inzira inochinja-chinja inogona kushandiswa kupinza simbi dzakasiyana siyana.MIG welding inzira huru yekubatanidza zvinhu pamwechete.Nekudaro, kana zvigadziriso zvisizvo zvikashandiswa, porosity inogona kuunzwa mune weld.Izvi zvinogona kukonzera matambudziko nesimba uye kuvimbika kwe weld.
Mune ino artical, isu tichatarisa zvimwe zvezvinokonzeresa porosity muMIG welding uye maitiro ekudzivirira.
Chii Chinokonzera Porosity MuMIG Welding?
Porosity imhando yekuremara kwewelding inogona kuitika mumawelds.Inoratidzika semaburi madiki mune weld uye inogona kuderedza chisungo pakati pezvidimbu zviviri zvesimbi.Porosity inogona kukonzerwa nezvinhu zvakasiyana, kusanganisira:
1) Fusion isina kukwana
Izvi zvinoitika kana welding arc ikasanyungudusa zvachose base simbi uye filler zvinhu.Izvi zvinogona kuitika kana welding muchina usina kuiswa kune chaiyo amperage kana kana welding torch isina kubatwa padhuze nesimbi.
2) Yakashata Gasi Coverage
MIG welding inoshandisa gasi rekudzivirira kuchengetedza weld kubva kuokisijeni nezvimwe zvinosvibisa.Kana iyo gasi inoyerera yakanyanya kuderera, porosity inogona kuitika.Izvi zvinogona kuitika kana gasi regulator isina kuiswa nenzira kwayo, kana kana paine kudonha mupombi yegesi.
3) Gasi Entrapment
Chimwe chikonzero che porosity kuvharirwa kwegasi.Izvi zvinoitika kana gasi mabubbles akavharirwa mudziva weld.Izvi zvinogona kuitika kana tochi yewelding isina kubatwa pakona chaiyo kana kana paine gasi rekudzivirira rakawandisa.
4) Tsvina Uye Zvinosvibisa
Porosity inogonawo kukonzerwa nekusvibiswa kwesimbi yepasi kana yekuzadza zvinhu.Tsvina, ngura, pendi, uye zvimwe zvinosvibisa zvinogona kukonzera porosity.Izvi zvinogona kuitika kana simbi isina kuchena isati yatungidzirwa, kana kana paine ngura kana pendi pamusoro.Izvi zvinosvibisa zvinogona kudzivirira weld kuti isanyatsobatana nesimbi.
5) Kusakwana Shielding Gasi
Chimwe chinokonzera porosity kusakwana kudzivirira gasi.Izvi zvinogona kuitika kana gasi risiri iro rinoshandiswa pakugadzira welding kana kana gasi rinoyerera risina kuiswa zvakanaka.
Unogona Sei Kudzivirira Porosity Kubva Kuitika Panguva yeMIG Welding process?
Pane zvinhu zvishoma zvaungaita kudzivirira porosity kuti isaitike panguva yeMIG welding process:
1. Shandisa zvigadziriso zvakafanira: Iva nechokwadi chokuti uri kushandisa zvigadziro zvakafanira pamushini wako we welding.Iyo amperage uye voltage inofanira kuiswa maererano nemirairo yemugadziri.
2. Shandisa gasi rakakodzera: Iva nechokwadi chekushandisa gasi rakakodzera kune yako welding process.Argon inowanzo shandiswa kune MIG welding.
3. Kuyerera kwegasi: Isa chiyero chekuyerera kwegasi maererano nemirairo yemugadziri.Gasi rakawandisa kana rakawandisa rinogona kukonzera porosity.
4. Chengetedza tochi pakona chaiyo: Iva nechokwadi kuti wakabata tochi pakona chaiyo kudzivirira kuvharwa kwegasi.Tochi inofanira kubatwa pakona ye10 kusvika ku15-degree kubva pamusoro pesimbi.
5. Shandisa simbi yakachena: Iva nechokwadi chekushandisa simbi yakachena, isina kusvibiswa kune weld yako.Chero tsvina, ngura, kana pendi pamusoro inogona kukonzera porosity.
6. Weld munzvimbo inofefetera zvakanaka: Weld munzvimbo ine mhepo inofefetera kuti usapinda gasi.Chengetedza gasi inogona kuvharirwa munzvimbo dzakapoteredzwa.
Porosity inogona kudzivirirwa nekutevera mazano aya.Nekushandisa zvigadziriso zvakaringana uye welding munzvimbo ine mhepo inofefetera, unogona kudzivirira dambudziko iri.
Yakajairwa Mishonga Yekugadzirisa Porosity Welds
Kune mashoma emishonga akajairika ekugadzirisa welds akabatwa neporosity:
1. Re-welding: Imwe mushonga wakajairika ndeyekushongedzazve nzvimbo yakakanganisika.Izvi zvinogona kuitwa ne welding pamusoro penzvimbo yakakanganisika ine yakakwirira amperage.
2. Porosity plugs: Imwe mushonga unozivikanwa ndeyekushandisa porosity plugs.Aya madiki madhisiki esimbi anoiswa pamusoro pemakomba ari weld.Porosity plugs inogona kutengwa kune dzakawanda welding supply zvitoro.
3. Kukuya: Imwe nzira ndeyekukuya nzvimbo yakakanganiswa uye woigadzira zvakare.Izvi zvinogona kuitwa neguyo rinobatwa nemaoko kana kuti angle grinder.
4. Welding waya: Mumwe mushonga kushandisa welding waya.Iyi iwaya yakatetepa iyo inoshandiswa kuzadza maburi ari muweld.Welding wire inogona kutengwa muzvitoro zvakawanda zvewelding.
Porosity inogona kugadziriswa nekushandisa imwe yeiyi mishonga inowanzoitika.Nekushongedzazve nzvimbo yacho kana kushandisa porosity plugs, unogona kugadzirisa dambudziko.
