Ka hopena o ke ano welding ma ka welding of high frequency longitudinal welded pipe making machine

ʻElua ala okiʻekiʻe-frequency wiliwili: kuʻi hoʻopili a me ka hoʻoheheʻe induction.

Hoʻohana ʻia ka hoʻopili ʻana i nā electrodes keleawe e pili ana me nā ʻaoʻao ʻelua o ka paipu kila e wili ʻia. He maikaʻi ke komo ʻana o ke au i hoʻokomo ʻia. Hoʻonui ʻia nā hopena ʻelua o ka manawa kiʻekiʻe ma muli o ka pilina pololei ma waena o nā electrodes keleawe a me ka pā kila. No laila, ʻoi aku ka kiʻekiʻe o ka maikaʻi o ka hoʻopili ʻana i ka welding a ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ka mana, hoʻohana nui ʻia i ka hana ʻana i nā paipu kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a koi pinepine ʻia ka hoʻopili ʻana i ka wā e hana ai i nā paipu kila mānoanoa. Eia nō naʻe, ʻelua mau hemahema i ka hoʻopili ʻana: ʻo ka mea hoʻokahi e pili ana ka electrode keleawe me ka pā kila, a komo koke ia; ʻO ka mea ʻē aʻe ma muli o ka mana o ka palahalaha o ka ʻili o ka pā kila a me ka pololei o ka ʻaoʻao, ʻaʻole maikaʻi ka paʻa o ka hoʻopili pili ʻana i kēia manawa, a ʻoi aku ka kiʻekiʻe o nā burrs o loko a me waho o ka weld. , 'A'ole i ho'ohana 'ia i ka wā e wiliwili ai i nā paipu me ka pololei a lahilahi.
Hoʻopili ʻia ka hoʻoheheʻe induction i hoʻokahi a ʻoi aʻe paha o nā wili induction ma waho o ka paipu kila e wili ʻia. ʻOi aku ka maikaʻi o ka hopena o ka nui ma mua o ka huli hoʻokahi, akā ʻoi aku ka paʻakikī o ka hana ʻana a hoʻokomo i nā coils induction multi-turn. ʻOi aku ka kiʻekiʻe o ka maikaʻi inā liʻiliʻi ka mamao ma waena o ka induction coil a me ka ʻili o ka paipu kila, akā maʻalahi ka hoʻokuʻu ʻana ma waena o ka induction coil a me ka paipu. ʻO ka maʻamau, pono e mālama i kahi āpau o 5-8 mm ma waena o ka coil induction a me ka ʻili paipu kila. I ka hoʻohana ʻana i ka welding induction, no ka mea ʻaʻole pili ka induction coil me ka pā kila, ʻaʻohe lole a me ka waimaka, a paʻa ke ʻano o ka induction, e hōʻoiaʻiʻo ana i ka paʻa o ka welding. Maikaʻi ka maikaʻi o ka ʻili o ka paipu kila i ka wā wili, a maʻemaʻe ka hili ʻana. No nā paipu pololei, hoʻohana ʻia ka welding induction.
