ʻEw pipeʻO ke kaʻina hana e pili ana i nā ʻano huahana like ʻole mai nā mea maka a hiki i nā huahana i hoʻopau ʻia, pono e hele i nā kaʻina hana, pono ka hoʻopau ʻana i kēia mau kaʻina hana i nā ʻano mīkini a me nā mea hana a me nā welding, nā mana uila, nā mea ʻike, kēia mau mea a me nā mea hana e like me i okoa.Pono ke kaʻina hana i nā ʻano hoʻonohonoho kūpono, ʻo ke kahe maʻamau o ka paipu welded kiʻekiʻe: open-book - strip leveler - ʻoki ʻia ke poʻo a me ka huelo - strip butt - looper accumulator - molding - welding - hoʻomaʻemaʻe i ka glitch - sizing - flaw - ʻoki lele - Ka hōʻoia mua - Hoʻopololei i ka paipu - ka hoʻoheheʻe ʻana i ka paipu - ka hoʻāʻo hydrostatic - ʻike hewa - Paʻi a uhi ʻia - pau.

Kiekie-frequency kuʻihao ua mau kahe ana ma ka workpiece pili ili o ka kiʻekiʻe-alapine o kēia manawa i hanaia e ka hoʻoikaika 'ana mehana a me ka forging ikaika e kau, no laila, i ka workpiece metala e hoʻokō i ka hana kuʻihao kekahi.Ua like ia me ka welding resistance maʻamau, akā nui nā ʻokoʻa koʻikoʻi.

High-frequency kuʻihao no carbon steel welded paipu hana ua 40 makahiki o ka mōʻaukala.High-frequency kuʻihao mana mana o nā mea like ʻole, anawaena a me ka mānoanoa o ka paia o ka paipu kila e hoʻokō i ka wikiwiki kuʻihao kiʻekiʻe (ʻoi aʻe ma mua o l0 mau manawa kiʻekiʻe ma mua o ka TIG kiʻekiʻe wili wikiwiki).No laila, ka hana ʻana o ke kumu nui o ka hoʻoheheʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe o ka hoʻoheheʻe ʻana i ke kila paipu i ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka wikiwiki kiʻekiʻe kiʻekiʻe o ka hoʻopili ʻana, paipu i loko o ka burr wehe paʻakikī, a ʻo kēia hoʻi ka kiʻekiʻe-frequency welded kila paipu ʻaʻole i kēia manawa no ka kemika. , ua ʻae ka ʻoihana nukili i kekahi o nā kumu.Mai ka mea hoʻoheheʻe, hiki i ka wili pinepine kiʻekiʻe ke wili i nā ʻano paipu kila.I ka manawa like, ka hoʻomohala ʻana i nā māka kila hou a me ka hoʻohālikelike ʻana i ka holomua o nā ʻano hana welding.
