Amaqela umngxuma

Ngexesha lokuphela, impembelelo yokukhusela ye-arc kunye ne-sla iyancipha kwaye kulula ukuba ibe yi-porosity kunye nezinye iziphene kwi-crater.Ubungakanani iziphene zingasuswa xa track elandelayo weld joints, ukuphelisa iziphumo ezilungileyo okanye ezimbi kuxhomekeke joint xa ukunyibilika, ukunyibilika kangangoko kunokwenzeka, kokukhona ukuphelisa ngokupheleleyo iziphene.Isikhululo samandla sebhoyila yokufudumeza imiphezulu ikakhulu i-calandria ukuphazamiseka, ukuphazamiseka ngendlela yesigqibo esidibeneyo ngakumbi endleleni xa amalungu e-crater ye-weld yexesha elifutshane lesenzo, kunzima ukoyisa iziphene, kunokukhokelela ngokulula ekukhupheni. umbhobho welded amalungu avela Amaqela imingxuma

Imingxuma yokuhlubula

Xa manual yombane arc welding ichaphazela i-angle ethambekileyo yempembelelo ekhuselayo ye-weld enkulu, ukuba ayikho kwinkqubo ye-welding ehlala igcina i-angle echanekileyo, ngokuqinisekileyo iya kubangela iigesi ezinobungozi ngaphandle kokungena ngaphandle, ngaphandle kokwanda kwe-engile ye-welding echanekileyo yobude bomthungo, iya kubumba. indawo yokuvula.Xa inqanaba umbhobho ubukhulu ubukhulu elimisiweyo zonke isikhundla ukuwelda intloko ukuwelda, ngenxa ukuphakama ukuze welder kufuneka athathe izikhundla welding zahlukile kwizikhundla ezahlukeneyo ukuze kugcinwe ukusebenza bar engile.Kwi-oblique oblique flat welding kunye nezikhundla eziphezulu ze-welding, i-welder kwi-posture inzima kakhulu, kunzima ukugcina imivalo ye-engile echanekileyo ihanjiswe, ngoko i-weld ezi ndawo zithandwa ukuhluba imingxuma.Isiphene se-welding ye-diameter encinci yenzeke ikakhulu ngenxa yokwakhiwa kweshelufu ayifanelekanga.Isantya kunye ne-swings transport inquma ubukhulu be-bead enye, isantya esithunyelwa ngokukhawuleza yenza ukuba i-electrode ifune ukutshintsha ngokukhawuleza i-angle, okanye ayikwazi ukwenza i-slag esebenzayo = ukukhuselwa ngokubambisana kwegesi.Emva kokufakwa phantsi kweemfuno zetyhubhu ezinodonga olucekethekileyo zigquma, ukuwelda ngesandla kufuneka kugcine isantya sothutho esikhawulezayo, kuya kubakho imingxunya.

Ukungena okungaphelelanga

I-Fin tube welded joints idla ngokucinga ngokulandelelanayo, kunye ne-welding shrinkage deformation, ekhokelela ekubeni kube nzima ukugcina i-cleaceparts efanelekileyo, xa ukuxhaswa kwe-melting degree bevel buthathaka, kubangele ukunqongophala kokungena.Steel stainless welding consumables otyhidiweyo flow metal ihlwempuzekile, kunye nobushushu ngokukhawuleza, ubushushu akukho lula ukugxila, nto leyo ebangele ukufudumeza arc kunye nokunyibilika isiseko metal okanye weld metal kunzima ngakumbi ukugcwalisa, ukwakheka ukungaphelelanga iziphene ukungena. .Umbhobho wodonga olungqingqwa omkhulu ubukhulu becala, amalungu xa ukuwelda ukuxhasa ukuba akungenwa kweengcambu, kubangwa kukungabikho kokungena;Ityhubhu enobubanzi obukhulu-ebiyelwe ngomphetho mkhulu, inokubangela ukungenwa okungaphelelanga.

I-Slag

Xa i-soldering, ubukhulu bentsimbi yokuzalisa buya kuchaphazela ukuphuphuma kwe-slag edadayo, iziphene ze-slag azikwazi ukugqithisa ngokupheleleyo ukuba i-slag yenziwe.Idayimitha enkulu etyebileyo-engqindilili umbhobho welding idla ngokusetyenziswa xa umsinga omkhulu, ubukhulu obukhulu be-single-pass welding slag edadayo nzima ngakumbi ukwenza iziphene ze-slag.I-Liquidity filler metal slag inempembelelo enkulu kwisizukulwana seziphene.Izinto zentsimbi yentsimbi etyhidiweyo yokungahambi kakuhle, kunye nokusetyenziswa kwe-weld encinci yangoku encinci, i-weld metal solidification, kunzima ukugqithisa ngokupheleleyo i-weld slag, ukwakheka kwe-slag yeziphene.I-welding ethe tyaba, i-soldering oblique welding head ithatha umzila, inombolo ye-lane njengoko iphathwa kakubi, inokubangela ukuba i-weld "ifile", ibe nethuba elikhulu le-slag defects.

Ukuqhekeka

I-TIG ibethe phantsi njengento encinci, uxinzelelo luya kwenza ukuba lwenzeke xa ugcwalisa iinyembezi ezibangelwa ukubunjwa kweentanda;hayi kwi-weld sub-layer encedisayo ngexesha elifanelekileyo emva kwe-welding, kodwa kunye nonobangela wokuqhekeka.Ukushisa kwe-preheat kunye nokugcinwa kwentonga ye-welding engafanelekanga, ukusetyenziswa okungafanelekanga, kuya kwandisa ithuba lokuqhekeka.
