Iimbangela zeBubbles kwiindawo zeWeld koomatshini bokuWelding abaPhakathi beFrequency Spot?

Oomatshini bokuwelda amabala aphakathi badla ngokusetyenziswa ngokudibanisa amacandelo esinyithi kumashishini ahlukeneyo. Nangona kunjalo, omnye wemiceli mngeni 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 yangoku 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 ulungelelanise iiparitha ze-welding njengoko zifuneka ukuze uqinisekise ukudityaniswa 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.
