ʻO ke koho ʻana i ka electrode welding e like me ke ʻano kemika, nā waiwai mechanical, nā koi hana anti-cracking, i ka manawa like, me ka noʻonoʻo ʻana i ke ʻano o ka welding, ka mānoanoa kila, nā kūlana hana, ke koʻikoʻi, ka hana kuʻi ʻana a me nā mea ʻē aʻe.I ka wā e pono ai, e hana i ka ho'āʻo welding, e hoʻolālā i nā ʻano ʻenehana kūpono, a laila e hoʻoholo i ke koho ʻana o ka electrode.
E hoʻohana maʻamau ʻia ka electrode wili kila kila a me ka ikaika o nā māka kila, e noʻonoʻo ana i ke ʻano paʻakikī, ka pā, ka ʻoʻoleʻa nui, ka haʻahaʻa ikaika, ka wili maikaʻi ʻole, hoʻohana maʻamau i ka plastic, kiʻekiʻe ka hopena o ka paʻakikī, ka hana kūʻē ʻana i ka hana maikaʻi o ka electrode hydrogen haʻahaʻa. , egE7018，E7016.Inā loaʻa nā koi kūikawā no ke kūlana welding, e hoʻohana ana i ka electrode kūikawā kūpono, e like me ka electrode, grounding electrode o vertical down welding etc. E6011, E6010.I mea e hoʻomaikaʻi ai i ka maikaʻi o ka welding, hiki ke hoʻohana ʻia ka hao pauka electrode.
Ma waho aʻe o ka weld cooling rate wikiwiki, hoʻonui i ka ikaika, maʻalahi ka hana ʻana i nā māwae weld.I ka manawa like, hiki ke koho i ka ikaika ma mua o ke kumu metala haʻahaʻa haʻahaʻa o ka electrode;haʻahaʻa kalapona kila a me ka haʻahaʻa alloy kila ma waena o dissimilar kila kuʻihao, kila ua maʻamau hoʻohana me ka haʻahaʻa ikaika pae e pili ana i ka electrode a noonoo haʻahaʻa-alloy mea kila, e koho haʻahaʻa hydrogen type ua kūpono.
No ka wiliwili ʻana i ke kila kalapona, ma muli o ke kila i loaʻa i ke kalapona kiʻekiʻe, e hoʻonui ana i ka manaʻo o ka welding crack, maʻamau i hoʻohana ʻia i nā electrodes hydrogen haʻahaʻa a me ka preheating, ke ʻano hoʻoluʻu lohi a me nā ana kaʻina hana kuʻi, hiki iā ʻoe ke koho.E6013, J422a pela aku..
E pili ana i ka hoʻoheheʻe kila kila, loaʻa nā mea kalapona kiʻekiʻe, nā mea hana koʻikoʻi, ka hoʻolālā paʻakikī, maʻalahi ka hana ʻana i ka māwae wiliwili, i ka wā lōʻihi ka mea i ʻoi aku ka kaulana.General koho o ka haʻahaʻa hydrogen type kuʻihao electrode, a lawe i ka preheating, lohi hooluolu a me na ano a me ke kaʻina hana kuʻihao a me nā ana 'ē aʻe.
Pono ia e hōʻoia i ka maikaʻi o ka welding a ma ka workpiece weld e maʻemaʻe, ʻaʻohe aila, ʻōpala, wai, pena a me ka lepo, etc., ma ka hoʻohana ʻana i nā electrodes hydrogen haʻahaʻa.
(No ka haʻahaʻa hydrogen electrodes, welding electrodes e 350 DEG C bakena no 1 hola, a me ka maloʻo me ka hoʻohana, a maʻalahi paha e hana porosity, slag, māwae a me nā hemahema. , ina i ka makū, e like me ke aʻo manual wela kuʻihao ma mua o ka kukeʻana, akā, ka wela kiʻekiʻe e luku i ka hana kuʻihao kaʻina hana.
