Loaʻa maikaʻi ʻole ka weldability kiʻekiʻe Carbon Steel ma muli o kāna ʻike kalapona kiʻekiʻe.ʻO nā hiʻohiʻona wili e like me kēia:
(1) maikaʻi ʻole thermal conductivity, ʻokoʻa ka wela nui ma waena o ka weld zone a me ka ʻāpana unheated.I ka wā e maʻalili ai ka loko i hoʻoheheʻe ʻia, hiki i ke koʻikoʻi kūloko o ka weld ke hana maʻalahi.
(2) ʻoi aku ka maʻalahi i ke kinai ʻana a ua maʻalahi ka hana ʻana o martensite ma kahi kokoke-seam zone.Ma muli o ka hana o ke koʻikoʻi o ka hale, hoʻopuka ka ʻāpana kokoke i ka māwae anu.
(3) ma muli o ka mana o ke kiʻekiʻe wela, ulu wikiwiki ka palaoa, maʻalahi ka carbide e hōʻiliʻili a ulu ma ka palena o ka palaoa, e hoʻonāwaliwali ai ka weld a emi ka ikaika o ka hui kuʻi.
(4) ʻoi aku ka maikaʻi o ke kila kalapona kiʻekiʻe e hana i nā māwae wela ma mua o ke kila kalapona waena
ʻO ke kila kalapona kiʻekiʻe he ʻano kila kalapona me w (c) > 0.6%.He ʻoi aku ka ʻoi aku o ka paʻakikī a hana i ka martensite kalapona kiʻekiʻe ma mua o ke kila kalapona waena, a ʻoi aku ka maʻalahi i ka hoʻokumu ʻana i nā māwae anu.
I ka manawa like, ʻo ka hale martensite i hoʻokumu ʻia i ka HAZ he mau waiwai paʻakikī a palupalu, e alakaʻi ana i ka emi ʻana o ka plasticity a me ka paʻakikī o ka hui.No laila, ʻoi aku ka maikaʻi o ka weldability o ke kila kalapona kiʻekiʻe, a pono e lawe ʻia ke kaʻina hana kuʻihao kūikawā, e hōʻoia i ka hana o ka mea hoʻohui.
No laila, i ka hoʻolālā welding, ʻaʻole i hoʻohana pinepine ʻia.Hoʻohana nui ʻia ke kila kalapona kiʻekiʻe no nā ʻāpana mīkini e koi ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, e like me nā rotary shafts, nā mīkini nui a me nā hui.
I mea e mālama ai i ke kila a hoʻomaʻamaʻa i ka ʻenehana hana, hana pinepine ʻia kēia mau ʻāpana mīkini i ke ʻano welded.I ka hana ʻana i nā mīkini koʻikoʻi, e hālāwai pū nā ʻāpana kila kalapona kiʻekiʻe i nā pilikia welding.
I ka hana ʻana i ke kaʻina hana kuʻi ʻana o nā ʻāpana kila kalapona kiʻekiʻe, pono ia e kālailai i nā ʻano hemahema a pau a lawe i nā kaʻina hana kuʻi.
