ʻO Kina hale kila hale noho hale hale kila kila

ʻO ka maikaʻi oNa Hale Paa kilapili pono ka welding i ka palekana o ka papahana holoʻokoʻa, no laila ʻo ka hoʻāʻo ʻole ʻana i nā welds he loulou nui loa. Loaʻa ka hoʻāʻo ʻana Weld i kēia mau mea:

ʻO ka hoʻāʻo ʻole ʻana i nā hemahema o loko i nā welds
(1) Nānā Penetrant ʻO ka nānā ʻana ʻo Penetrant he ala nānā ʻole luku ʻole e hoʻohana ana i ka hopena komo o kahi mea hoʻonani fluorescent a i ʻole kahi ʻulaʻula e hōʻike i nā ʻāpana o nā hemahema. ʻO nā ʻano hana maʻamau ka nānā ʻana i ka fluorescence a me ka nānā kala.
E kāpīpī i kahi kala ʻulaʻula me ka hiki ke komo maikaʻi ma ka ʻili o ka weldment i hoʻomaʻemaʻe ʻia. Ma hope o ke komo ʻana i loko o nā hemahema ma ka ʻili weld, e holoi i ka ʻili o ka weldment maʻemaʻe. A laila e hoʻopili i kahi ʻāpana o ka wai hōʻike keʻokeʻo. Ma hope o ka maloʻo ʻana, ua hoʻopili ʻia ka kala i komo i loko o nā hemahema o ka weldment e ka mea hōʻike keʻokeʻo ma muli o ka hana capillary, e hōʻike ana i nā ʻulaʻula o nā hemahema ma ka ʻili. Hiki ke hoʻohana ʻia ka hoʻāʻo Penetrant ma luna o kekahi mea me ka ʻili maʻemaʻe.
(2) ʻO ka nānā ʻana i ka ʻāpana magnetik ʻO ka nānā ʻana i ka mea hoʻokalakupua e hoʻokalakupua i ka weldment i loko o kahi māla ikaika, no laila e hele nā ​​laina laina ma waena o ka weld. I ka wā e ʻike ai i nā hemahema ma luna a kokoke paha i ka ʻili o ka weld, hoʻopuka ʻia ka leakage flux magnetic a huki i ka hao hao hao i hoʻopuehu ʻia ma ka ʻili o ka weld. ʻulaʻula.
Hiki ke hoʻoholo ʻia ka wahi a me ka nui o ka hemahema ma muli o ke ʻano o ka adsorption o ka pauka hao. He kūpono wale ka nānā ʻana i ka ʻāpana magnetic no ka ʻike ʻana i nā hemahema ma ka ʻili a i ʻole kokoke i ka ʻili o nā mea ferromagnetic.
(3) Nānā Radiographic ʻElua ʻano o ka nānā ʻana i ka radiographic: X-ray a me Y-ray inspection. Ke hele nā ​​kukuna i ka weld i nānā ʻia, inā loaʻa kahi kīnā, ʻo ka attenuation o ka ray e hele ana i ka hemahema he liʻiliʻi, no laila ʻoi aku ka maʻalahi o ke kiʻi ma ke kua o ka weld. Ma hope o ka hoʻomohala ʻia ʻana o ke kiʻiʻoniʻoni, e hōʻike ʻia nā wahi ʻeleʻele ma ka wahi hemahema. A i ʻole nā ​​kaha.
He pōkole a wikiwiki hoʻi ka manawa irradiation X-ray, akā paʻakikī a pipiʻi nā mea hana, a ʻoi aku ka liʻiliʻi o kona hiki ke komo ma mua o ka Y-ray. Pono ka mānoanoa o ka weldment e ʻike ʻia ma lalo o 30mm. He maʻalahi nā mea nānā Y-ray, maʻalahi ke hana, hiki ke komo ikaika, a hiki ke hoʻomālamalama i nā papa kila 300mm. ʻAʻole koi ʻia ka mana i ka wā transillumination, e maʻalahi ia no nā hana kahua. Akā i ka ʻike ʻana ma lalo o 50mm, ʻaʻole kiʻekiʻe ka sensitivity.
(4) Ultrasonic ho'āʻo Ultrasonic ho'āʻo hoʻohana i ka loina hiki ke hoʻolaha nā hawewe kani ultrasonic i loko o ka metala a e hoʻohālikelike ʻia a hoʻopaʻa ʻia i ka wā e ʻike ai i ka pilina ma waena o ʻelua media e ʻike i nā hemahema o loko o ka weld.
