Iimbangela zeBubbles kwiindawo zeWeld koomatshini bokuWelding abaPhakathi beFrequency Spot?

Oomatshini bokuwelda amabala aphakathi badla ngokusetyenziswa ngokudibanisa amacandelo esinyithi kumashishini ahlukeneyo.Nangona kunjalo, omnye wemicelimngeni abanokuthi bahlangabezane nayo abaqhubi kukubunjwa kwamaqamza okanye i-voids kwiindawo ze-weld.Eli nqaku lijonga izizathu ezibangela ukwenzeka kwamaqamza kwiwelding yendawo ejikelezayo kwaye lixoxe ngezisombululo ezinokubakho ukulungisa lo mba.

Izinto ezibangela amaqamza kwiindawo zeWeld:

1. Izinto ezingcolisayo kuMphezulu:Esinye sezizathu eziphambili zamaqamza kwiindawo ze-weld kubukho bezinto ezingcolileyo, ezifana neoli, igrisi, i-rust, okanye ukungcola, phezu kwentsimbi edibeneyo.Ezi zingcolisi ziyakwazi ukuphunga ngexesha lenkqubo ye-welding, ekhokelela ekubunjweni kwamaqamu.
2. Ukufakwa kwi-Oxidation:Ukuba iindawo zetsimbi azicocwanga ngokufanelekileyo okanye zikhuselwe, i-oxidation ingenzeka.Imiphezulu ene-oxidized inokunciphisa amandla okudibanisa ngexesha le-welding, ekhokelela ekwenziweni kwezithuba okanye i-voids.
3. Uxinzelelo olungonelanga:Uxinzelelo olungahambelaniyo okanye olungonelanga lwe-electrode lunokuthintela ukudibanisa isinyithi esifanelekileyo.Oku kunokubangela izithuba phakathi kwemigangatho yesinyithi, okubangela ukuba amaqamza enze.
4. UkuWelding ngokwaneleyo ngoku:I-Welding nge-current engonelanga ingakhokelela ekudibaneni okungaphelelanga phakathi kweentsimbi.Ngenxa yoko, izikhewu zinokuvela, kwaye amaqamza anokuvela ngenxa yezinto ezenziwe ngumphunga.
5. Usulelo lwe-Electrode:Ii-electrode ezisetyenziswa kwi-welding yendawo zinokungcoliswa bubutyobo ngokuhamba kwexesha, nto leyo echaphazela umgangatho we-weld.I-electrodes engcolileyo inokukhokelela ekudibaneni kakubi kunye nobukho bamaqamza.
6. Iiparamitha zeWelding engalunganga:Ukuseta ngokungalunganga iiparameters ze-welding, ezifana ne-welding current, ixesha, okanye amandla e-electrode, kunokukhokelela ekudibaneni okungonelanga kunye nokudalwa kwamaqamu.

Izisombululo zokujongana namaQela kwiindawo zeWeld:

1. Ukulungiswa komphezulu:Coca ngokucokisekileyo kwaye uhlambulule umphezulu wesinyithi phambi kokuba udibanise ukususa nakuphi na ungcoliseko olunokuba negalelo ekwenziweni kwamaqamza.
2. Ukhuseleko lomphezulu:Sebenzisa ii-anti-oxidation ezifanelekileyo okanye unyango lokuthintela i-oxidation kwiindawo zentsimbi.
3. Yandisa Uxinzelelo:Qinisekisa ukuba uxinzelelo lwe-electrode luhambelana kwaye lufanelekile kwizinto ezidityanisiweyo.Uxinzelelo olwaneleyo lunceda ukufezekisa ukudibanisa okufanelekileyo kunye nokuthintela izithuba.
4. I-Welding echanekileyo yangoku:Misela i-welding current ngokuhambelana neenkcukacha zezinto kunye nenkqubo ye-welding.Umbane owaneleyo ubalulekile ekufezekiseni i-weld eyomeleleyo kunye ne-bubble-free.
5. ULondolozo lwe-Electrode rhoqo:Gcina i-electrode icocekile kwaye ikhululekile kwi-debris ukuqinisekisa ukusebenza kakuhle kunye nokuthintela imiba enxulumene nokungcoliseka.
6. Uhlengahlengiso lweParameter:Jonga kabini kwaye uhlengahlengise iiparamitha ze-welding njengoko zifuneka ukuze uqinisekise ukudibanisa okufanelekileyo kunye nokunciphisa umngcipheko wokwakheka kweqamza.

Ubukho bamaqamza kwiindawo ze-weld kumatshini we-welding we-medium frequency spot unokuchaphazela kakhulu umgangatho kunye nokuthembeka kwee-welds.Ukuqonda izinto ezinokuthi zibe ngunobangela walo mba kubalulekile ukuba abaqhubi bathathe amanyathelo okhuseleko ayimfuneko kwaye baphumeze izisombululo zokuthintela ukwenziwa kwamaqamza.Ngokulungiswa komphezulu ofanelekileyo, ukugcina uxinzelelo oluhambelanayo, ukusebenzisa iiparamitha ezifanelekileyo ze-welding, kunye nokuqinisekisa ukucoceka kwe-electrode, abaqhubi banokuphucula iinkqubo zabo ze-welding kwaye bavelise umgangatho ophezulu, i-bubble-free welds kwizicelo ezahlukeneyo.
