Nā Hana Nānā no nā Hui Weld i nā Mīkini Welding Spot Welding Energy

I nā mīkini wiliwili wahi e mālama ai i ka ikehu, ʻo ka hōʻoia ʻana i ka maikaʻi a me ka pololei o nā hui weld he mea nui loa.No ka hoʻokō ʻana i kēia, hoʻohana ʻia nā ʻano nānā like ʻole e loiloi i nā hui weld no nā hemahema, e like me ka fusion kūpono ʻole, nā māwae, a i ʻole porosity.Ke ʻimi nei kēia ʻatikala i nā ʻenehana like ʻole no ka nānā ʻana i nā hui weld i nā mīkini wiliwili wahi hoʻopaʻa ikehu, e hāʻawi ana i nā mea hoʻohana i nā mea hana waiwai no ka mālama ʻana i nā welds kiʻekiʻe.

1. Nānā Kiʻi: ʻO ka nānā ʻike maka ke ʻano maʻamau a maʻamau no ka loiloi ʻana i nā hui weld.Nānā makaʻala nā mea hoʻohana i ka wahi weld no nā hemahema i ʻike ʻia, e like me ka hui ʻole ʻana, nā ʻino o ka ʻili, a i ʻole ka pau ʻana.Pono kēia ʻano i ka maka i hoʻomaʻamaʻa ʻia a me nā kūlana kukui kūpono e ʻike pono i nā pilikia e hiki mai ana.
2. Nā ʻenehana hoʻāʻo ʻaʻole luku (NDT): a.Ka Ho'āʻo Ultrasonic: Hoʻohana ka hoʻāʻo ʻana i nā hawewe kani kiʻekiʻe e ʻike i nā hemahema o loko a i ʻole nā ​​hemahema o nā hui weld.Hoʻouna ʻia nā hawewe kani ultrasonic ma o ka hui weld, a ʻike ʻia nā nalu i ʻike ʻia e ʻike i nā mea ʻino.He mea maikaʻi kēia ʻenehana no ka ʻike ʻana i nā māwae lalo a i ʻole porosity.

b.Ka Ho'āʻo Radiographic: ʻO ka hoʻāʻo radiographic e pili ana i ka hele ʻana i nā kukui X a i ʻole nā ​​​​kukui gamma ma o ka hui weld a kiʻi i kahi kiʻi ma ke kiʻiʻoniʻoni a i ʻole ka mea ʻike kikohoʻe.Hiki i kēia ʻano hana ke hōʻike i nā hemahema o loko, e like me ke komo ʻole ʻana a i ʻole nā ​​haʻahaʻa.ʻOi aku ka maikaʻi o ka hoʻāʻo ʻana i ka radiographic no nā hui wiliwili mānoanoa a paʻakikī paha.

c.ʻO ka hoʻāʻo ʻana i ka ʻāpana Magnetic: Hoʻohana ʻia ka hoʻāʻo ʻana i nā mea ferromagnetic.Hoʻopili ʻia kahi māla magnetic i ka hui weld, a hoʻopili ʻia nā ʻāpana magnetic i ka ʻili.ʻO nā pōʻino i haki ʻia i ka ʻili e hui pū nā ʻāpana magnetic, e hōʻike ana i kahi hemahema.

d.Ho'āʻo Penetrant Dye: Hoʻohana ʻia ka hoʻāʻo ʻana i ka wai no ka ʻike ʻana i nā hemahema o ka ʻili i nā hui weld.Hoʻopili ʻia kahi waihoʻoluʻu i ka ʻili, a ma hope o ka manawa i ʻōlelo ʻia, wehe ʻia ke kala keu.A laila hoʻohana ʻia kahi mea hoʻomohala, kahi e huki ai i ka wai paʻa i waho o nā hemahema o ka ʻili, e ʻike ʻia.

3. Ho'āʻo ʻino: I kekahi mau hihia, pono ka hoʻāʻo ʻino e loiloi i ka maikaʻi o ka hui weld.Hoʻopili kēia i ka wehe ʻana i kahi ʻāpana laʻana o ka hui weld a kau ʻia i nā hoʻāʻo like ʻole, e like me ka hoʻāʻo ʻana i ka tensile, ke kulou ʻana, a i ʻole ka hoʻāʻo ʻana i ka paʻakikī.Hāʻawi ka hoʻāʻo luku ʻana i ka ʻike kikoʻī e pili ana i nā waiwai mechanical o ka hui weld a hiki ke hōʻike i nā hemahema huna.

He mea koʻikoʻi ka nānā ʻana i nā hui weld i nā mīkini hoʻopaʻa ʻana i ka ikehu no ka hōʻoia ʻana i ka maikaʻi o ka weld a me ka paʻa o ke kūkulu ʻana.Ma ka hoʻohana ʻana i ka nānā ʻike maka, nā ʻenehana hoʻāʻo ʻino ʻole (e like me ka hoʻāʻo ʻana i ka ultrasonic, ka hoʻāʻo radiographic, ka hoʻāʻo ʻana i ka ʻāpana magnetic, a me ka hoʻāʻo dye penetrant), a, inā pono, hoʻāʻo luku, hiki i nā mea hana ke loiloi pono i nā hui weld no nā hemahema.ʻO ka hoʻokō ʻana i kahi papahana nānā piha e kōkua i ka mālama ʻana i nā kūlana kiʻekiʻe o ka maikaʻi a me ka hilinaʻi i nā noi wili wahi hoʻopaʻa ikehu.Hiki i ka nānā mau ʻana ke ʻike koke a me ka hoʻonā ʻana i kekahi pilikia, e alakaʻi ana i ka maikaʻi o ka weld a me ka hana wili holoʻokoʻa.
