Iipores kwi-weld seam ngumcimbi oqhelekileyo womgangatho ngexeshaukuwelda irobhothi. Ubukho be-pores bunokukhokelela ekunciphiseni amandla e-welds, kwaye kubangele nokuqhekeka kunye nokuqhekeka. Ezona zizathu ziphambili zokwenza iipores kwi-robot welds ziquka ezi zilandelayo:
1. Ukhuseleko lwerhasi olulambathayo:
Ngethuba lenkqubo ye-welding, ukunikezelwa kweegesi ezikhuselayo (ezifana ne-argon, i-carbon dioxide, njl.) akwanelanga okanye azilingani, ezihlulekayo ukuhlukanisa ngokufanelekileyo i-oksijeni, i-nitrogen, njl. emoyeni, okubangelwa ukuxuba igesi kwi-melt pool kunye ukubunjwa kwee-pores.
2. Ukuphathwa kakubi komphezulu wezixhobo ze-welding kunye nesiseko sezinto:
Kukho ukungcola okunje ngeoli yeoli, i-rust, ukufuma, kunye nezikali ze-oxide kumphezulu we-welding material okanye isiseko sesinyithi. Obu kungcola bubola kubushushu obuphezulu be-welding ukuvelisa igesi, engena kwidama elinyibilikisiweyo kwaye yenze i-pores.
3. Iiparamitha zenkqubo ye-welding engafanelekanga:
Ukuba i-current, i-voltage, kunye nesantya se-welding ziphezulu kakhulu okanye ziphantsi kakhulu, zikhokelela ekungashukumi ngokwaneleyo kwechibi lokunyibilika kunye nokungakwazi ukubaleka kakuhle kwerhasi; Okanye ukuba i-angle yokuvuthela yegesi yokukhusela ayifanelekanga, inokuchaphazela umphumo wokukhusela igesi.
4. Uyilo lwe-weld olungekho ngqiqweni:
Ukuba i-gap phakathi kwe-weld seams inkulu kakhulu, i-fluidity yensimbi ye-pool etyhidiweyo impofu, kwaye igesi kunzima ukuyikhupha; Okanye imilo ye-weld seam inzima, kwaye igesi akulula ukubaleka kubunzulu be-weld seam.
5. Ukufuma okuphezulu kwindawo ye-welding:
Ubumanzi obusemoyeni bubola bube yirhasi yehydrogen kumaqondo obushushu aphezulu e-welding, ene-solubility ephezulu kwidama elinyibilikisiweyo kwaye ayinakubaleka ngexesha ngexesha lenkqubo yokupholisa, yenze imingxunya.
Amanyathelo okusombulula ingxaki ye-porosity kwii-welds zerobhothi zezi zilandelayo:
1. Lungiselela ukhuseleko lwerhasi:
Qinisekisa ukuba ukucoceka kwegesi ekhuselayo kuhambelana nomgangatho, umlinganiselo wokuhamba uphakathi, kwaye umgama phakathi kwe-nozzle kunye ne-weld seam ifanelekile, ukwenza ukhuseleko oluhle lomkhusane womoya.
●Sebenzisa ukubunjwa kwegesi efanelekileyo kunye nomlinganiselo wokuxuba, njengokusebenzisa i-low okanye i-ultra-low ye-hydrogen welding rods kunye neengcingo, ukunciphisa umthombo wegesi ye-hydrogen.
2. Unyango olungqongqo lwangaphezulu:
Coca ngokucokisekileyo umphezulu weizinto zokuweldakunye nesiseko sesinyithi phambi kwe-welding, susa ukungcola okufana neoli, i-rust, kunye nokufuma, kwaye wenze unyango lwangaphambili xa kuyimfuneko.
Kwiindawo apho umswakama unokuthi kwenzeke ngexesha lenkqubo ye-welding, thatha amanyathelo okomisa, njengokusebenzisa i-weld seam dryer okanye ukufudumala i-workpiece.
3. Lungisa iiparamitha zenkqubo ye-welding:
Khetha isantya esifanelekileyo sangoku, i-voltage, kunye nesantya se-welding esekwe kwisixhobo se-welding, isiseko semathiriyeli, kunye nesikhundla se-welding ukuze uqinisekise ukushukuma okuphakathi kunye nexesha lokubaleka kwerhasi yedama elinyibilikisiweyo.
Lungisa i-angle yokuvuthela yegesi ekhuselayo ukuqinisekisa ukuba igesi igubungela ngokulinganayo i-weld seam.
4. Phucula uyilo lweweld:
Lawula isithuba se-weld seam phakathi koluhlu olufanelekileyo ukuphepha ukuba likhulu kakhulu okanye lincinci kakhulu.
Kwii-welds ezinzima, iindlela ezifana ne-welding edibeneyo, i-filler preset metal, okanye ukutshintsha ulandelelwano lwe-welding zingasetyenziselwa ukuphucula iimeko zokukhutshwa kwegesi.
5. Lawula indawo ye-welding:
Zama ukuwelda kwindawo eyomileyo nengena umoya ukunqanda ukufuma okugqithisileyo.
Kwiindawo apho ukufuma kungenakulawulwa khona, amanyathelo afana nokusebenzisa i-hygroscopics kunye nokufudumala kwe-welding seam kunokuqwalaselwa ukunciphisa impembelelo yokufuma.
6. Ukubeka iliso kunye nolawulo lomgangatho:
Jonga rhoqo ukusebenza kwezixhobo ze-welding, ezifana nemitha yokuhamba kwegesi, imibhobho ye-welding gun, njl., Ukuqinisekisa imeko yabo yokusebenza kakuhle.
Ixesha langempela lokujonga inkqubo ye-welding, njengokusebenzisa inkqubo yokubeka iliso yenkqubo ye-welding, ukufumanisa ngokukhawuleza kunye nokulungelelanisa iiparitha ezingaqhelekanga.
Yenza uvavanyo olungonakalisi (njengovavanyo lwe-ultrasonic, uvavanyo lwe-radiographic, njl.) emva kwe-welding ukukhangela ngokukhawuleza kwaye uphathe i-welds equkethe i-porosity. Ukusetyenziswa ngokubanzi kwamanyathelo angasentla kunokunciphisa ngokufanelekileyo ukuveliswa kweepores kwi-robot welds kunye nokuphucula umgangatho we-welding.
Iimbangela ze-porosity kwi-robot welds zibandakanya ukungcoliseka komphezulu we-welding material, ukungonelanga kokukhusela igesi, ukulawulwa okungafanelekanga kwe-welding yangoku kunye ne-voltage, kunye nesantya esiphezulu se-welding. Ukuyicombulula le ngxaki, kufuneka sithathe amanyathelo ahambelanayo, kubandakanywa ukusebenzisa izinto ezicocekileyo ze-welding, ukukhetha iigesi zokukhusela ngokufanelekileyo kunye nokulawula izinga lokuhamba, ukubeka iiparitha ze-welding ngokufanelekileyo, kunye nokulawula isantya se-welding ngokwemeko. Kuphela ngaxeshanye ukujongana nemiba emininzi sinokuthi sithintele ngokufanelekileyo kwaye sisombulule ingxaki ye-porosity kwi-welding ye-robot, kunye nokuphucula umgangatho we-welding.
