ʻO ka mid-frequency direct current spot welding he kaʻina hana wiliwili maikaʻi loa e hāʻawi ana i nā pono he nui i nā noi ʻoihana like ʻole. Ma kēia ʻatikala, e ʻimi mākou i nā hiʻohiʻona kūʻokoʻa a me nā pono o kēia ʻenehana welding.
Ua loaʻa ka ʻike nui ʻana o ka wiliwili kiko waena (MFDC) i ka ʻoihana hana no kāna hana wiliwili maikaʻi a me nā pono he nui. Hōʻike ʻia kēia ʻenehana e kona hoʻohana ʻana i ke au pololei (DC) ma waena o nā alapine waena, maʻamau ma waena o 1000 Hz a me 100,000 Hz. Hāʻawi kēia ʻano pololei a hoʻomalu ʻia o ka welding i kekahi mau hiʻohiʻona kupaianaha.
1. Ka pololei a me ka Mana
ʻO kekahi o nā ikaika nui o ka wiliwili wahi MFDC ʻo ia ka pololei a me ka mana. Ma ka hoʻohana ʻana i ka DC ma waena o nā alapine waena, hiki i nā welders ke hoʻokō i nā hopena pololei a kūlike. ʻOi aku ka maikaʻi o kēia kikoʻī i ka hana ʻana me nā mea lahilahi a i ʻole nā mea paʻakikī, no ka mea e hōʻemi ana i ka pōʻino a hōʻoia i kahi weld kiʻekiʻe.
2. Wahi Hoʻoemi ʻia i ka wela (HAZ)
Hoʻoemi ʻia ka wela o ka MFDC i ka wā o ke kaʻina hana kuʻi ʻana i hoʻohālikelike ʻia me nā ʻano kuʻuna kuʻuna. Loaʻa kēia i kahi wahi liʻiliʻi liʻiliʻi i ka wela (HAZ), he mea koʻikoʻi no ka mālama ʻana i ka pono o ka mea kumu. ʻO ka HAZ i hōʻemi ʻia e hōʻemi i ka distortion a me ka pilikia o nā loli metallurgical, e lilo ia i koho kūpono no nā noi kahi e mālama ʻia ai ka ikaika a me nā waiwai.
3. Hoʻoikaika ikaika
ʻO ke kuʻi ʻana o ka mid-frequency he mea maikaʻi loa ka ikehu. ʻO ka hoʻohana ʻana i nā lako mana AC kiʻekiʻe i nā ʻōnaehana welding MFDC e hiki ai ke kaohi pololei i ka hoʻokomo ʻana i ka ikehu. ʻAʻole kēia e hōʻemi wale i ka hoʻohana ʻana i ka ikehu akā kōkua pū kekahi i ka mālama kālā i ka holo lōʻihi.
4. ʻOi aku ka wikiwiki o ka welding cycles
ʻIke ʻia ʻo MFDC wahi wiliwili no kāna mau pōʻai kuʻi wikiwiki. ʻO ke ʻano kiʻekiʻe-frequency o kēia manawa e hiki ai i ka hoʻoheheʻe wikiwiki a me ka paʻa ʻana o ka wai weld, e hopena i nā manawa hana wikiwiki. He pōmaikaʻi koʻikoʻi kēia i nā kaiapuni hana kiʻekiʻe.
5. Hiki ke hoʻololi
Hiki ke hoʻololi ʻia nā ʻōnaehana welding MFDC a hiki ke hoʻopili ʻia e kūpono i nā noi wili like ʻole. Hiki iā lākou ke wili i nā ʻano mea like ʻole, me nā hui like ʻole o nā metala, a hiki ke hoʻokomo i nā mānoanoa mea like ʻole. ʻO kēia versatility e hana ai i ka welding MFDC i kūpono no nā ʻano ʻoihana like ʻole, mai ka hana kaʻa a hiki i ka hana uila.
6. Ka maikaʻi a me ke kūlike
He mea koʻikoʻi ke kūpaʻa i ka hana ʻana, a ʻoi aku ka maikaʻi o MFDC welding ma kēia ʻano. ʻO ka mana pololei ma luna o nā palena welding e hōʻoia i nā welds likeʻole i loko o ke kaʻina hana, e ho'ēmi ana i ka pono no ka hana hou a hoʻonui i ka maikaʻi holoʻokoʻa o ka huahana i hoʻopauʻia.
He koho maikaʻi loa ka mid-frequency direct spot welding no nā ʻano hana wiliwili ma muli o kona pololei, kaohi, ka ikehu, a me ka hoʻololi. ʻO kona hiki ke hana i nā welds kiʻekiʻe me nā wahi liʻiliʻi i hoʻopili ʻia i ka wela e lilo ia i koho koho no nā ʻoihana e koi ana i ka hana a me ke kūlike. Ke hoʻomau nei ka ʻenehana i ka holomua, ʻo ka MFDC wahi wiliwili e noho mau ana i pōhaku kihi o ka hana hou ʻana, e hāʻawi ana i ka hoʻonui ʻana i ka pono a me ka mālama kālā.
