Xa kufikwa kumacandelo entsimbi yesiko kunye neendawo ezivaliweyo, i-welding inokusombulula inkitha yemingeni yoyilo.Yiyo loo nto sinikezela ngeenkqubo ezahlukeneyo zokuwelda njengenxalenye yokwenziwa kwesiko lethu, kubandakanyaukuwelda indawo,ukuwelda komthungo, iiweld zefillet, iplagi welds, kunye ne tack welds.Kodwa ngaphandle kokuthumela iindlela ezifanelekileyo ze-welding, inkqubo ye-welding light-gauge sheet sheet inokuba yingxaki kwaye ithande ukwaliwa.Esi sithuba sebhlog siza kuxubusha ukuba kutheni sisisebenzisaI-Cold Metal Transfer (CMT) i-weldingngaphezulu kwe-MIG yesiqhelo ye-welding (igesi ye-inert yensimbi) okanye i-TIG ye-welding (i-tungsten faka igesi).

th ezinye iindlela welding

Kwinkqubo yokuwelda, ubushushu obuvela kwitotshi yokuwelda butshisa i-workpiece kunye nocingo lwefidi etotshini, luyanyibilika kwaye ludibanise.Xa ubushushu buphezulu kakhulu, i-filler inokunyibilika ngaphambi kokuba ifike kwindawo yokusebenza kwaye ibangele amathontsi esinyithi atshize kwindawo.Ngamanye amaxesha, i-weld inokutshisa ngokukhawuleza i-workpiece kwaye ibangele ukuphazamiseka okanye kwiimeko ezimbi kakhulu, imingxuma inokutshiswa kwindawo yakho.

Iintlobo ze-welding ezisetyenziswa ngokuqhelekileyo yi-MIG kunye ne-TIG ye-welding.Ezi zombini zinemveliso yobushushu ephezulu kakhulu xa kuthelekiswaI-Cold Metal Transfer (CMT) i-welding.

Kumava ethu, i-TIG kunye ne-MIG welding ayifanelekanga ukujoyina i-light-gauge sheet sheet.Ngenxa yobushushu obugqithisileyo, kukho i-warping kunye ne-meltback, ngakumbi kwintsimbi engenasici kunye ne-aluminiyam.Phambi kokwaziswa kwe-CMT welding, ukuwelda i-welding light-gauge sheet sheet ithande ukuba luhlobo oluthile lobugcisa kunenkqubo yokuvelisa ngobunjineli.

Isebenza njani i-CMT?

I-welding ye-CMT ine-arc ezinzile ngokukodwa.I-arc ye-pulsed yenziwe kwisigaba sangoku esisisiseko esinamandla aphantsi kunye nesigaba sangoku se-pulsing esinamandla amakhulu ngaphandle kweesekethe ezimfutshane.Oku kukhokelela ekubeni kungabikho sitshizi siveliswayo.(I-Spatter ngamathontsi ezinto ezityhidiweyo ezenziwe kwindawo okanye kufuphi ne-arc ye-welding.).

Kwinqanaba langoku lokubetha, amathontsi e-welding akhutshiwe ngendlela ekujoliswe kuyo ngokusebenzisa i-pulse yangoku enedosi echanekileyo.Ngenxa yale nkqubo, i-arc yazisa kuphela ubushushu ixesha elifutshane kakhulu ngexesha le-arc-burning phase.

Ubude be-arc bufunyenwe kwaye bulungelelaniswe ngomatshini.I-arc ihlala izinzile, kungakhathaliseki ukuba yintoni umphezulu we-workpiece efana okanye ukukhawuleza komsebenzisi welds.Oku kuthetha ukuba i-CMT ingasetyenziswa kuyo yonke indawo nakuyo yonke indawo.

Inkqubo yeCMT ngokwasemzimbeni ifana ne-MIG welding.Nangona kunjalo, umahluko omkhulu kwisondlo socingo.Kunokuba uqhubeke uye phambili kwi-weld pool, kunye ne-CMT, ucingo luhlehlisiwe ukuhamba kwangoku kwangoku.I-weld wire kunye negesi ekhuselayo yondliwa nge-torch ye-welding, i-arcs yombane phakathi kwe-weld wire kunye ne-welding surface - oku kubangela ukuba incam yocingo lwe-weld luxutywe kwaye lusetyenziswe kwindawo ye-welding.I-CMT isebenzisa ukusebenza okuzenzekelayo kunye nokuvalwa kwe-arc yokufudumeza ukutshisa ngokucwangcisiweyo kunye nokupholisa ucingo lwe-weld ngelixa ungenisa ucingo ngaphakathi nangaphandle kokunxibelelana ne-weld pool amaxesha amaninzi ngomzuzwana.Kuba isebenzisa isenzo sokutyhala endaweni yomsinga oqhubekayo wamandla,Ukuwelda kwe-CMT kuvelisa isinye kwishumi kuphela sobushushu okwenziwa yi-MIG.Oku kwehliswa kobushushu lolona ncedo lukhulu lwe-CMT kwaye yiyo loo nto ibizwa ngokuba kugqithiso lwentsimbi “lubandayo”.

Inyani eyonwabileyo ekhawulezayo: Umphuhlisi we-CMT welding uyichaza njenge, "kushushu, kuyabanda, kushushu, kuyabanda, kuyabanda."

Ukuba unayo nayiphi na imibuzo malunga nokufaka i-welding kuyilo lwakho,fikeleleukuqalisa.Iprotocase inokwenza izivalo zakho zesiko kunye neenxalenye, ukuya kuthi ga kwiintsuku ezi-2-3, ngaphandle kwee-odolo ezincinci.Ngenisa umgangatho wobuchwephesha beprototypes enye okanye uyilo olusezantsi kwaye uqalise iiprojekthi zakho namhlanje.
