ʻO nā ʻano hoʻomaʻamaʻa hoʻomaʻamaʻa maʻamau no nā mīkini wiliwili ʻokoʻa

ʻO ka nānāʻana i ka welding he mea nui ia o ke kaʻina hana wili, no ka mea e hōʻoiaʻiʻo ana i ka maikaʻi a me ka hilinaʻi o nā welds i hana ʻia e nā mīkini wiliwili wahi.Ma kēia ʻatikala, e kūkākūkā mākou i nā kaʻina nānā wili maʻamau i hoʻohana ʻia i nā mīkini wiliwili wahi waena.

Nānā Kiʻi
ʻO ka nānā maka ke ʻano maʻamau a hoʻohana mau ʻia no ka nānā ʻana i nā welds.Hoʻopili ia i ka nānā ʻana i ka weld no nā hemahema ʻike ʻia, e like me nā māwae, porosity, a i ʻole ka hui ʻana ʻole.Hoʻohana ka mea nānā i nā mea hana like ʻole, e like me ke aniani hoʻonui a i ʻole ke aniani, e nānā i ka weld mai nā kihi like ʻole a hōʻoia i ka hoʻokō ʻana i nā kikoʻī i koi ʻia.
Nānā Lekiō
ʻO ka nānā ʻana i ka radiographic kahi ʻano hoʻāʻo ʻino ʻole e hoʻohana ana i nā kukui X a i ʻole nā ​​​​kukui gamma e nānā i ka weld no nā hemahema o loko.Hoʻohana ka mea nānā i kahi mīkini kūikawā e hana i ka radiation, a laila kuhikuhi ʻia i ka weld.A laila nānā ʻia ke kiʻi i loaʻa no ka hoʻoholo ʻana i ka maikaʻi o ka weld.
Nānā Ultrasonic
ʻO ka nānā ʻana i ke kani kani kekahi ʻano hana hoʻāʻo ʻole e hoʻohana ana i nā hawewe kani kiʻekiʻe e nānā i ka weld no nā hemahema o loko.Hoʻohana ka mea nānā i kahi mīkini kūikawā e hana i nā hawewe kani, a laila kuhikuhi ʻia i ka weld.A laila ʻike ʻia ka leo e hoʻoholo ai i ka maikaʻi o ka weld.
Nānā Penetrant Dye
ʻO ka nānā ʻana i ka dye penetrant he ala nānā ʻili e pili ana i ka hoʻopili ʻana i kahi wai wai i ka ʻili o ka weld.A laila ʻae ʻia ka wai e komo i nā hemahema o ka ʻili, e like me nā māwae a i ʻole porosity, ma mua o ka holoi ʻia ʻana.A laila hoʻohana ʻia kahi mea hoʻomohala, nāna e huki i ke kala mai nā hemahema a ʻike ʻia no ka nānā ʻana.
Nānā Mākēneki
ʻO ka nānā ʻana i nā ʻāpana magnetik kahi ʻano nānā ʻē aʻe e pili ana i ka hoʻopili ʻana i nā ʻāpana magnetic i ka ʻili o ka weld.Hoʻopili ʻia nā ʻāpana i nā hemahema o ka ʻili, e like me nā māwae a i ʻole porosity, a hana i kahi hōʻailona ʻike ʻia o ka hemahema.A laila nānā ka mea nānā i ka weld e hoʻoholo i ka maikaʻi.
I ka hopena, he mea koʻikoʻi ka nānā ʻana o ka welding i ke kaʻina hana kuʻi, a aia kekahi mau ʻano loiloi maʻamau i hoʻohana ʻia i nā mīkini wiliwili wahi.ʻO ka nānā ʻana i nā hiʻohiʻona, ka nānā ʻana i ka radiographic, ka nānā ʻana i ke kani ultrasonic, ka nānā ʻana i ka dye penetrant, a me ka nānā ʻana i nā ʻāpana magnetic nā ʻano koʻikoʻi āpau no ka hōʻoia ʻana i ka maikaʻi a me ka hilinaʻi o nā welds i hana ʻia.
