He ʻano ʻenehana wiliwili me kahi mōʻaukala lōʻihi, i haku ʻia me nā ʻāpana wili i hui ʻia i loko o kahi hui pūhaka a kaomi ʻia ma waena o nā electrodes ʻelua, a hoʻohana i ka wela kūpaʻa e hoʻoheheʻe i ka metala kumu e hana i kahi wahi kuʻi.
Hoʻopili ʻia nā ʻāpana welding e kahi kumu hoʻoheheʻe liʻiliʻi, pono e hoʻohele like ʻia a symmetrically ma luna o ka ili hoʻopaʻa ʻana o nā welds ʻelua, a loaʻa iā ia nā ʻano ʻenehana o ka welding ma lalo o ka manawa kiʻekiʻe, ka manawa pōkole a me ke kaomi.
Spot welding mea he wela-mechanical (ikaika) hui hui o ka welding kaʻina, e like me ke ano o ka mana lako hiki ke maheleia i hookahi-ʻaoʻao kuʻihao a me ka lua-ʻaoʻao kuʻihao, hiki ke welded i loko o ka pōkole manawa, no laila, kiʻekiʻe pono. Hoʻopaʻa ʻia ka wela ma kekahi ʻāpana, ʻaʻole hiki i ka mea welded ke hoʻololi i ka wela, a maikaʻi ka maikaʻi o ka welding. No ka mea, ʻo ia ka welding aunoa, hiki i kekahi ke weld, a ʻaʻohe hana akamai e koi ʻia.
Ka rationality o welding wahi hoonohonoho omīkini wiliwili wahi alapinepine: Hoʻohana pinepine ʻia ke ʻano kuʻi wiliwili wahi i nā pilina he nui, ʻo kāna hoʻonohonoho ka hapa nui o ka lālani hoʻokahi, i kekahi manawa hiki ke hoʻonui i ka lālani, i ka lālani hoʻokahi hui kuʻi ʻana i hoʻohui ʻia me ke koʻikoʻi shear, akā e hoʻokau pū kekahi i ke koʻikoʻi tensile ma muli o ka ikaika eccentric. , i loko o ka multi-laina wahi kuʻihao hui, tensile stress mea uuku, noiʻi hōʻike i ka helu o solder ami oi aku ma mua o 3 mea pono ole, no ka mea, oi aku mamua o 3 lalani hiki ole ke hoonui i ka hiki ana.
I ka manawa like, pono e hoʻomaopopo ʻia ʻaʻole hiki ke hoʻokō i ka ikaika o ka hui a me ka metala kumu i kahi lālani hoʻokahi o nā hui welded wahi, ʻo ka hoʻohana wale ʻana i nā lālani he nui (3 lālani) i hoʻonohonoho ʻia i nā hui solder, hiki ke hoʻomaikaʻi i ka hopena. o ka ipukukui hapa, e hoemi i ke koʻikoʻi koʻikoʻi koʻikoʻi, inā hoʻohana ʻia ke ʻano o ka lālani staggered, ʻoi aku ka maikaʻi o ke kūlana, ma ke kumumanaʻo, hiki iā ʻoe ke kiʻi i kahi hui welded me ka ikaika o ka metala kumu.
Hiki iā mākou ke ʻike i ke ʻano o ka pāpaʻi ʻana i ka wā e hoʻohana ai i ka mīkini wiliwili wahi waena, hiki ke maʻalahi i ka ʻoki ʻana i ka metala kumu, ka hoʻohaumia ʻana i nā maka aniani pale o ka welding, a me ka pepa aniani hau o ka kānana a me ka pahu pahu. No laila pehea ʻoe e pale ai i kēia mai ka hana ʻana?
I ke kaʻina hana, hiki ke hoʻoheheʻe ʻia ke kikowaena o ka welding i ka manawa pōkole, piʻi koke ka wela o ka metala, ua lōʻihi ka hoʻoheheʻe ʻana o ka wai hoʻoheheʻe ʻia, a hoʻoheheʻe ʻia ka wai mai ke kumu hoʻoheheʻe ʻia ma lalo o ka hana o ke kaomi. , ka hopena i ka paʻi.
Aia kahi hoʻolaha hoʻolaha wela Q=I²RT, e hōʻike ana he maʻalahi ka spatter ke hiki ke kiʻekiʻe ka wela, no laila hiki ke hoʻomalu ʻia ka spatter mai ka Angle o kēia manawa a me ke kū'ē; ʻO ka mānoanoa o kēia manawa: aia ka lepo ma ka ʻili o ka mea hana a i ʻole he ʻokoʻa ma waena o ka mea hana. Electrode: Electrode cap asymmetry a ʻaʻahu paha i kēia manawa e hoʻonui i ka spatter.
Pāʻani mua:
ʻAʻole kūpono ka hoʻomaʻemaʻe ʻana i ka weld, ʻaʻole kūlike ka puʻukū ma ka ʻili pili, e hopena i ka hoʻoheheʻe mua ʻana ma muli o ke kiʻekiʻe o kēia manawa kūloko, i kēia manawa ma muli o ka nele o ka pale plastic e hiki mai ke ʻano splashing.
Pāʻani lohi:
Ke ulu nei ke kumu hoʻoheheʻe a me ka hoʻololi ʻana, ma waho aʻe o ke ʻano kūpono o ke kaomi electrode, i mea e haki ai i ke apo plastic i ke kumu radial o ka splashing kūloko, e hoʻoheheʻe ai i waho ma ka ʻaoʻao axial break surface, hana ʻia kēia kūlana i ka nui o kēia manawa. , lōʻihi loa ka manawa mana, hiki ke hoʻopōkole i ka manawa mana a hoʻemi i ke ala o kēia manawa e pale ai.
