Yintoni ebangela iPorosity kwi-MIG Welding?

Xa i-welding, injongo kukudala ibhondi eyomeleleyo, engenamthungo phakathi kweengcezu ezimbini zetsimbi.Ukuwelda kwe-MIG yinkqubo eguquguqukayo enokusetyenziswa ukuwelda iintlobo ngeentlobo zesinyithi.I-MIG welding yinkqubo enkulu yokudibanisa izixhobo kunye.Nangona kunjalo, ukuba izicwangciso ezingalunganga zisetyenzisiwe, i-porosity ingangeniswa kwi-weld.Oku kunokubangela iingxaki ngamandla kunye nokunyaniseka kwe-weld.

Kule artical, siza kujonga ezinye zezizathu ze-porosity kwi-MIG welding kunye nendlela yokukhusela.

Yintoni ebangela iPorosity kwi-MIG Welding?

I-Porosity luhlobo lwe-welding defect enokuthi yenzeke kwi-welds.Kubonakala njengemingxuma emincinci kwi-weld kwaye ingenza buthathaka ibhondi phakathi kwamaqhekeza amabini esinyithi.I-porosity inokubangelwa zizinto ezahlukeneyo, eziquka:

1) I-Fusion engaphelelanga

Oku kwenzeka xa i-arc ye-welding inganyibiliki ngokupheleleyo isiseko sesinyithi kunye nezinto zokuzalisa.Oku kunokwenzeka ukuba umatshini we-welding awumiselwanga kwi-amperage echanekileyo okanye ukuba i-torch ye-welding ayibanjwanga ngokwaneleyo kwintsimbi.

I-2) Ukubonelela ngegesi engalunganga

I-MIG welding isebenzisa igesi yokukhusela ukukhusela i-weld kwi-oksijeni kunye nezinye izinto ezingcolileyo.Ukuba ukuhamba kwegesi kuphantsi kakhulu, i-porosity ingenzeka.Oku kunokwenzeka ukuba umlawuli wegesi akamiselwanga ngokuchanekileyo, okanye ukuba kukho ukuvuza kwi-hose yegesi.

3) Ukungena kwegesi

Omnye unobangela we-porosity kukufakwa kwegesi.Oku kwenzeka xa amaqamza erhasi ebanjiswa kwi-weld pool.Oku kunokwenzeka ukuba itotshi ye-welding ayibanjwanga kwi-engile echanekileyo okanye ukuba kukho igesi eninzi yokukhusela.

4) Ukungcola kunye nokungcola

I-Porosity inokubangelwa kukungcoliswa kwesiseko sesinyithi okanye i-filler material.Ukungcola, umhlwa, ipeyinti, kunye nezinye izinto ezingcolileyo zinokubangela i-porosity.Oku kunokwenzeka ukuba isinyithi asicocekanga phambi kwe-welding, okanye ukuba kukho i-rust okanye ipeyinti phezu komhlaba.Ezi zingcolisi zinokuthintela i-weld ukuba idibanise ngokufanelekileyo kwintsimbi.

5) Ukunganelanga kweGesi yokuKhusela

Omnye unobangela we-porosity kukungonelanga kwerhasi yokukhusela.Oku kunokwenzeka ukuba igesi engafanelekanga isetyenziselwa inkqubo ye-welding okanye ukuba ukuhamba kwegesi akusetwanga ngokuchanekileyo.

Ungakuthintela njani i-Porosity ukuba ingenzeki Ngexesha leNkqubo yokuWelding ye-MIG?

Kukho izinto ezimbalwa onokuthi uzenze ukukhusela i-porosity ukuba ingenzeki ngexesha lenkqubo ye-MIG ye-welding:

1. Sebenzisa useto oluchanekileyo: Qinisekisa ukuba usebenzisa iisetingi ezichanekileyo kumatshini wakho we-welding.I-amperage kunye ne-voltage kufuneka imiselwe ngokwemiyalelo yomenzi.

2. Sebenzisa igesi echanekileyo: Qinisekisa ukusebenzisa igesi echanekileyo kwinkqubo yakho ye-welding.IArgon iqhele ukusetyenziswa kwi-MIG welding.

3. Ukuhamba kwerhasi: Seta izinga lokuhamba kwerhasi ngokwemiyalelo yomenzi.Igesi eninzi kakhulu okanye encinci kakhulu inokubangela i-porosity.

4. Gcina itotshi kwi-engile echanekileyo: Qinisekisa ukuba itotshi uyibambe nge-engile echanekileyo ukunqanda ukubanjwa kwegesi.Itotshi kufuneka ibanjwe kwi-angle ye-10 ukuya kwi-15-degree ukusuka kumphezulu wesinyithi.

5. Sebenzisa isinyithi esicocekileyo: Qinisekisa ukusebenzisa isinyithi esicocekileyo, esingahlambulukanga kwi-weld yakho.Nakuphi na ukungcola, umhlwa, okanye ipeyinti emphezulu inokubangela i-porosity.

6. Weld kwindawo enomoya opholileyo: Weld kwindawo enomoya ukuze ugweme ukuvalelwa kwegesi.Irhasi yokukhusela inokuvaleleka kwiindawo ezivaliweyo.

I-Porosity inokuthintelwa ngokulandela la macebiso.Ngokusebenzisa iisetingi ezichanekileyo kunye ne-welding kwindawo enomoya, unokuphepha le ngxaki.

Izisombululo eziqhelekileyo zokulungisa iiWelds zePorosity

Kukho amayeza ambalwa aqhelekileyo okulungisa i-welds ezichatshazelwe yi-porosity:

1. Ukuwelda kwakhona: Elinye iyeza eliqhelekileyo kukuphinda udibanise indawo echaphazelekayo.Oku kunokwenziwa nge-welding phezu kwendawo echaphazelekayo kunye ne-amperage ephezulu.

2. Iiplagi ze-Porosity: Olunye unyango oluqhelekileyo kukusebenzisa iiplagi ze-porosity.Ezi ziidiski ezincinci zentsimbi ezibekwe phezu kwemingxuma kwi weld.Iiplagi ze-Porosity zingathengwa kwiindawo ezininzi zokubonelela nge-welding.

3. Ukugaya: Enye inketho kukusila indawo echaphazelekayo kwaye uphinde udibanise.Oku kunokwenziwa nge-grinder yesandla okanye i-angle grinder.

4. Ucingo lwe-welding: Olunye unyango kukusebenzisa ucingo lwe-welding.Olu lucingo olubhityileyo olusetyenziselwa ukugcwalisa imingxuma kwi weld.I-welding wire inokuthengwa kwiindawo ezininzi zokubonelela nge-welding.

I-Porosity inokulungiswa ngokusebenzisa elinye lala mayeza aqhelekileyo.Ngokuphinda udibanise indawo okanye usebenzise iiplagi ze-porosity, unokulungisa ingxaki.
