Iimfuno zoMgangatho weMidi-Frequency Direct Current Spot Welding

Kwiinkqubo zokwenziwa zale mihla, i-spot welding idlala indima ebalulekileyo ekudibaniseni izinto zentsimbi kunye. Oomatshini bokuwelda bamabala aphakathi kwe-frequency ngqo (MFDC) baye bazuza ukubaluleka ngenxa yokukwazi ukuvelisa iiwelds ezikumgangatho ophezulu ngokuchaneka nokusebenza kakuhle. Kweli nqaku, siza kuphonononga kwiimfuno eziyimfuneko zomgangatho wamanqaku e-weld aveliswa ngoomatshini bokuwelda bamabala beMFDC.

1. Ukuhambelana kwezinto: Ingqwalasela yokuqala kunye neyona nto iphambili ekufezekiseni umgangatho we-welds kukuqinisekisa ukuba izinto ezidityanisiweyo ziyahambelana. MFDC indawo welding ilungele uluhlu olubanzi lwesinyithi, kuquka intsimbi, stainless steel, aluminiyam, kunye nobhedu. Kubalulekile ukukhetha iiparamitha ezifanelekileyo ze-welding kunye nemathiriyeli ye-electrode kwindibaniselwano nganye yezinto ezithile ukufezekisa i-weld eyomeleleyo kunye neyomelele.
2. Amandla eWeld: Injongo ephambili yayo nayiphi na i-weld kukudala ibhondi eyomeleleyo phakathi kweentsimbi ezimbini. Umgangatho we-MFDC welding spot kufuneka ubangele iiwelds ezinokuqina okuphezulu kunye namandla okucheba, iqinisekisa ukuba ijoyinti inokumelana noxinzelelo kunye nemithwalo yoomatshini.
3. Ukungqinelana: Ukuhambelana ngundoqo ekufezekiseni i-welds ephezulu. Oomatshini bokuwelda indawo be-MFDC kufuneka bamiselwe kwaye bagcinwe ukuze babonelele nge-welds engaguqukiyo kuyo yonke imveliso. Oku kubandakanya ukugcina ulungelelwaniso olufanelekileyo lwe-electrode, uxinzelelo, kunye nokuhamba kwangoku.
4. Indawo echatshazelwe bubushushu obuncinane (HAZ): Ukushisa okugqithisileyo kunokukhokelela kwindawo echaphazelekayo yokushisa (HAZ) ejikeleze i-weld, enokuthi ibe buthathaka kwizinto eziphathekayo. Umgangatho we-MFDC welding welding yehlisa i-HAZ, iqinisekisa ukuba imathiriyeli ejikelezileyo igcina iimpawu zayo zokuqala kangangoko kunokwenzeka.
5. Akukho Porosity okanye Inclusions: I-Porosity kunye nokubandakanywa ngaphakathi kwe-weld kunokuphazamisa ingqibelelo yayo. Umgangatho we-MFDC welding spot uvelisa iiwelds ezinobuncinci ukuya kungabikho porosity okanye inclusions, iqinisekisa ijoyinti engenasiphako.
6. Imbonakalo yeCosmetic: Nangona ukunyaniseka kwesakhiwo se-weld kubaluleke kakhulu, imbonakalo ye-cosmetic nayo ibalulekile, ngakumbi kwizicelo apho i-welds ibonakala. Umgangatho we-MFDC wokuwelda amabala kufuneka uphumele ekucoceni nasekuthandeni ukuwelda.
7. Ukujongwa kweNkqubo: Ukuphumeza inkqubo yokubeka iliso kunye namanyathelo okulawula umgangatho kubalulekile. Oku kubandakanya ukuhlolwa rhoqo, uvavanyo olungonakalisi, kwaye, ukuba kuyimfuneko, uvavanyo olutshabalalisayo lokuqinisekisa umgangatho we-weld.
8. Iiparamitha zeWelding: Ukubeka ngokufanelekileyo iiparamitha ze-welding ezifana nezangoku, ixesha, kunye noxinzelelo kubalulekile. Ezi parameters kufuneka zilungelelaniswe ngokobukhulu bezinto eziphathekayo, uhlobo, kunye neemfuno ze-welding ezithile.
9. Amanyathelo okhuseleko: Ukhuseleko luyiyona nto iphambili kuyo nayiphi na imisebenzi ye-welding. Abaqhubi kufuneka baqeqeshelwe iindlela ezikhuselekileyo zokuwelda, kwaye izixhobo zokuwelda kufuneka zihlangabezane nayo yonke imigangatho yokhuseleko ukukhusela iingozi kunye nokukhusela abasebenzi.

Ukuqukumbela, ukufikelela amanqaku weld ezikumgangatho ophezulu kunye MFDC indawo koomatshini ukuwelda kufuna ingqalelo ngenyameko ukuhambelana eziphathekayo, ukungaguquguquki, amandla, kunye nokunciphisa iziphene. Ukuphumeza iiparamitha ezifanelekileyo ze-welding, iinkqubo zokubeka iliso, kunye nokuqinisekisa ukuba amanyathelo okhuseleko akhona ngamanyathelo ayimfuneko ekuhlangabezaneni nezi mfuno zomgangatho. Xa isenziwa ngenkuthalo, i-MFDC i-spot welding inokuhambisa i-welds echanekileyo, eyomeleleyo, kwaye ethembekileyo, iyenza ibe bubuchule obuxabisekileyo kumashishini ahlukeneyo okuvelisa.
