Ke Kaʻina no ka ʻike ʻana i ka maikaʻi o ka lae Weld ma nā mīkini hoʻoheheʻe wahi kūʻē

ʻO ke kuʻi ʻana wahi kūʻē he ʻenehana i hoʻohana nui ʻia i nā ʻoihana hana e hoʻohui pono i nā ʻāpana metala. ʻO ka hōʻoia ʻana i ka maikaʻi o nā wahi weld he mea koʻikoʻi e mālama i ka kūpaʻa a me ka palekana o ka huahana hope. Ma kēia ʻatikala, e kūkākūkā mākou i kahi ala no ka ʻike ʻana i ka maikaʻi o ka weld point i nā mīkini wili wahi kūʻē.

ʻO ka wiliwili wahi kūʻē he hana ia e hoʻohui ʻia ai ʻelua ʻāpana metala ma ka hoʻopili ʻana i ka wela a me ke kaomi ma nā wahi kikoʻī. ʻO ka maikaʻi o ka helu weld e pili ana i nā kumu like ʻole, me nā ʻāpana welding, nā waiwai waiwai, a me ke ʻano o nā electrodes welding. ʻO ka ʻike a me ka hōʻoia ʻana i ka maikaʻi o kēia mau wahi weld he mea nui ia e pale ai i nā hemahema a mālama i ka hilinaʻi o nā mea welded.

Hana no ka ʻike ʻana i ka maikaʻi o ka lae Weld

1. Nānā Kiʻi: ʻO ke ala maʻalahi loa e ʻike ai i ka maikaʻi o ka weld point ma o ka nānā ʻana. Hiki i nā mea hana akamai ke nānā i nā wahi weld no nā hewa ʻole e like me nā māwae, nā hakahaka, a i ʻole ka lawa ʻole o ke komo ʻana. Hāʻawi ka nānā ʻana i nā manaʻo manaʻo koke a ʻo ia ka laina mua o ka pale ʻana i ka mana maikaʻi.
2. Ka ho'āʻo ultrasonic: Kani ultrasonic ho'āʻo mea he non-destructive hana e utilizes kiʻekiʻe-frequency kani hawewe e nānā i ka weld i loko. Hiki iā ia ke ʻike i nā hemahema o loko i ʻike ʻole ʻia ma o ka nānā ʻana i nā hiʻohiʻona, e like me nā māwae huna a i ʻole nā ​​​​puka.
3. Nānā X-ray: ʻO ka nānā ʻana i ka X-ray kekahi ʻano hana ʻino ʻole e hāʻawi i kahi kiʻi kikoʻī o ke ʻano o loko o ka weld. He mea maikaʻi loa ia i ka ʻike ʻana i nā hemahema o loko a me ka hōʻoia ʻana i ka pono o nā wahi weld koʻikoʻi.
4. Weld au a me Voltage kiai: ʻO ka nānā ʻana i ka manawa welding a me ka volta i ka wā o ka welding kaʻina hiki ke hāʻawi i ka ʻike manawa maoli e pili ana i ka maikaʻi o ka weld. Hiki ke hōʻike i nā pilikia me ka weld, e like me ka hoʻopili maikaʻi ʻole a i ʻole nā ​​​​mea pili ʻole.
5. Ho'āʻo Shear and Tensile: No ka loiloi ʻana i ka ikaika mechanical o ka weld, hiki ke hoʻokō ʻia nā laʻana i nā hoʻāʻo ʻāwī a me ka tensile. Hoʻoholo kēia mau hoʻāʻo i ka hiki o ka weld ke kū i nā ikaika o waho a hōʻoia i ka hoʻokō ʻana i nā kikoʻī ikaika i koi ʻia.
6. ʻIkepili Microstructural: ʻO ka nānā ʻana i ka microstructural ka nānā ʻana i ka microstructure o ka weld ma lalo o kahi microscope. Hiki i kēia ʻano hana ke hōʻike i ka ʻike e pili ana i ke ʻano o ka weld o ka weld, hiki ke hoʻopilikia i kona mau waiwai mechanical.
7. Hoʻāʻo Penetrant Dye: ʻO ka hoʻāʻo ʻana i ka dye penetrant kahi ʻano i hoʻohana ʻia e ʻike i nā hemahema o ka ʻili i nā welds. Hoʻopili ʻia kahi mea pena penetrant i ka ʻili weld, a holoi ʻia nā mea pena keu. E komo ke kala i loko o nā hemahema o ka ʻili, e ʻike ʻia ma lalo o ke kukui UV.
8. Ho'āʻo Mākēneki: He kūpono kēia ʻano hana no ka ʻike ʻana i nā hemahema o ka ʻili a me ka ʻili i nā mea ferromagnetic. Hoʻopili ʻia nā ʻāpana magnetic i ka weld, a ʻike ʻia nā pilikia i ka māla magnetic i hoʻokumu ʻia e nā hemahema.

ʻO ka hōʻoia ʻana i ka maikaʻi o nā wahi weld i nā mīkini wili wahi kūʻē he mea koʻikoʻi no ka mālama ʻana i ka pono o nā mea welded. ʻO ka hoʻohana ʻana i ka hui pū ʻana o ka nānā ʻana a me nā ʻano hoʻāʻo hoʻāʻo ʻole e like me ka hoʻāʻo ultrasonic, ka nānā ʻana i ka X-ray, a me ka weld nānā i kēia manawa hiki ke kōkua i ka ʻike ʻana i nā hemahema a me nā ʻokoʻa mai nā kūlana maikaʻi. ʻO ka hoʻāʻo ʻana i ka mīkini a me ka loiloi microstructural e hōʻoia hou i ka hoʻokō ʻana o nā welds i ka ikaika a me nā kikoʻī kikoʻī. Ma ka hoʻokō ʻana i kēia mau ʻano, hiki i nā mea hana ke hana i nā huahana welded kiʻekiʻe me ka hilinaʻi.
