ʻO ke koho ʻana i nā lako welding a me ka hoʻoponopono ʻana i ke kaʻina hana no ke kila ikaika kiʻekiʻe

ʻO nā kila ikaika kiʻekiʻe, i waiwai nui ʻia no ka ikaika tensile kiʻekiʻe a me ke kūpaʻa luhi, hoʻohana nui ʻia i nā ʻāpana kaumaha e like me nā mīkini hana, nā alahaka, a me nā moku kaomi. Akā, ʻoi aku ka koi o kā lākou weldability ma mua o nā kila maʻamau; Ma o ke koho ʻana i nā mea hana ʻepekema wale nō, hiki ke pale ʻia nā māwae, ka ʻole o ka hui ʻana, a me nā hemahema ʻē aʻe i ka wā e hōʻoiaʻiʻo ana i ka hoʻokō ʻana o ka hui pū ʻana me ka metala kumu.

Pono ke koho ʻana i nā mea hana ma luna o ʻelua mana nui: 'ka hoʻomalu ikehu pololei' a me ka ' hiki ke hoʻololi.' No nā ʻāpana kila ikaika i ʻoi aku ka mānoanoa ma mua o 8 mm, ʻo ka wiliwili kikohoʻe submerged-arc ka koho mua. Mālama ia a hoʻokō i nā polokalamu no kēia manawa, ka uila, a me ka wikiwiki o ka huakaʻi, e hāʻawi ana i ka paʻa, ka wela kiʻekiʻe e hōʻoiaʻiʻo i ke komo piha ʻana i ka wā e pale ai kahi papa flux i ka wai hoʻoheheʻe mai ka lewa e hōʻemi i ka porosity. No nā kila ikaika kiʻekiʻe-e like me 700 MPa kaʻa kaʻa kaʻa—ʻo ka welder laser me ka pololei 0.01 mm beam e hoʻokō i ka hoʻopili pololei haʻahaʻa-hoʻokomo, e pale ana i ka nalowale o ka ikaika mai ka wela wela.

Mālama ka hoʻoponopono ʻana i ka maikaʻi o ka weld. ʻO ka hoʻomoʻa mua ʻana i nā ʻāpana a hiki i 200-350 °C e hoʻolohi i ka hoʻolili ʻana a hoʻopaʻa i ka pohā anu. I ka wā hoʻoheheʻe multi-pass, pono e noho ka mahana ma waena o 150 ° C e pale i ka embrittlement. Pono nā metala hoʻopiha piha i ka ikaika base-metal: i ka wā e kuʻi ai i ke kila 960 MPa, e hoʻohana i ka electrode haʻahaʻa-hydrogen o ka papa like, i kālua ʻia ma 350 °C a paʻa i loko o ka umu paʻa e hōʻemi i ka haki ʻana i ka hydrogen-induced.

No nā ʻokoʻa like ʻole o ka ikaika kiʻekiʻe-e laʻa, Q690 a i Q890-pulsed MIG welding modulates arc energy. ʻO nā pōʻai puʻupuʻu 'wela-ʻanuʻu' e hoʻohālikelike i ka wai i hoʻoheheʻe ʻia me ka laula o ka ʻāpana wela, e hāʻawi ana i ka ikaika like ma waena o ka wahi hoʻololi.

ʻO ke kuʻi kila ikaika kiʻekiʻe e koi ana i ka pololei o nā mea hana a me ka mana o ke kaʻina hana. ʻO ka synergy o nā lako waiwai a me nā kaʻina hana i hoʻopaʻa ʻia ke kī i ka lanakila ʻana i nā bottlenecks welding. ʻO nā mīkini wiliwili PDKJ, i hana ʻia no nā kila ikaika kiʻekiʻe, hoʻohui i ka mana hoʻohālikelike pololei me ka hiki ke hoʻololi i ke kaʻina hana, e hāʻawi ana i nā hopena kūpaʻa a hilinaʻi no kēlā me kēia papa o nā mea ikaika kiʻekiʻe-he kaulike kūpono o ka maikaʻi a me ka huahana.

Inā loaʻa iā ʻoe nā koi mīkini wili, e ʻoluʻolu e kelepona iā Ms. Zhao
