ʻIke Hohonu o nā ʻenehana kiaʻi maikaʻi no nā hui welded ma nā mīkini wiliwili kikoʻī Inverter-Frequency.

He mea koʻikoʻi ka maikaʻi o nā hui welded i hana ʻia e nā mīkini welded spot welding medium-frequency no ka hōʻoia ʻana i ka pono a me ka hana o nā huahana like ʻole. No ka hoʻokō ʻana i nā welds kūpaʻa a hilinaʻi, pono ia e hoʻokō i nā ʻenehana nānā pono kūpono. Hāʻawi kēia ʻatikala i kahi hiʻohiʻona piha o nā ʻenehana nānā i hoʻohana ʻia e loiloi i ka maikaʻi o nā hui welded i nā mīkini wiliwili wahi inverter medium-frequency.

1. Nānā Kiʻi: ʻO ka nānā ʻana he ʻenehana kumu no ka loiloi i ka maikaʻi o nā hui welded. Nānā makaʻala nā mea hana i ka wahi weld e ʻike ai i nā hemahema maʻamau e like me ka hui ʻole ʻana, ka spatter nui, nā māwae, a i ʻole ke kūkulu ʻia ʻana o nā nugget kūpono ʻole. Hiki ke hana ʻia ka nānā ʻana me ka hoʻohana ʻana i nā mea hana hoʻonui, e like me nā microscopes a i ʻole borescopes, e hoʻomaikaʻi i ka nānā ʻana i nā welds paʻakikī a paʻakikī paha.
2. Nā Hana Ho'āʻo Non-Destructive (NDT): He hana koʻikoʻi nā ʻano hoʻāʻo non-destructive i ka loiloi ʻana i ka pono o loko a me ka ʻili o nā hui welded me ka ʻole o ka pōʻino. ʻO kekahi mau ʻenehana NDT maʻamau no ka nānā ʻana i ka maikaʻi ma nā mīkini wiliwili wahi inverter medium-frequency:

• Ka Ho'āʻo Ultrasonic (UT): Hoʻohana ʻo UT i nā hawewe kani alapine kiʻekiʻe e ʻike i nā hemahema o loko e like me ka nele o ka hui ʻana, porosity, a i ʻole nā ​​māwae o ka hui welded. ʻIke ʻia nā nalu i ʻike ʻia e ʻike i ka nui, ke ʻano, a me kahi o nā hemahema.
• Ho'āʻo Radiographic (RT): RT pili i ka hoʻohana ʻana i nā kukui X a i ʻole nā ​​kukui gamma e hana i nā kiʻi o ka hui welded. Hiki iā ia ke ʻike i nā hemahema o loko, e like me nā inclusions, voids, a i ʻole misalignment. Hiki i nā kiʻi radiographic ke hāʻawi i ka ʻike kikoʻī e pili ana i ka maikaʻi weld a me ka pololei.
• ʻO ka hoʻāʻo ʻana i ka ʻāpana mākēneki (MT): Hoʻohana nui ʻia ʻo MT no nā mea ferromagnetic. ʻO ke kaʻina hana e pili ana i ka hoʻohana ʻana i kahi māla magnetic a me ka hoʻohana ʻana i nā ʻāpana magnetic. ʻO nā hemahema i haki ʻia i ka ʻili, e like me nā māwae a i ʻole nā ​​ʻūhā, e hoʻopau i ke kahua magnetic, e hōʻiliʻili ai nā ʻāpana ma nā wahi kīnā a ʻike ʻia.
• ʻO Dye Penetrant Testing (PT): He kūpono ka PT no ka ʻike ʻana i nā hemahema o ka ʻili i nā mea porous ʻole. ʻO ke kaʻina hana e pili ana i ka hoʻopili ʻana i kahi waihoʻoluʻu i ka ʻili, e ʻae iā ia e komo i nā hemahema o ka ʻili. Wehe ʻia ke kala ʻoi loa, a hoʻohana ʻia kahi mea hoʻomohala e hoʻonui i ka ʻike ʻana o nā hemahema.

3. Mechanical Testing: Hoʻohana ʻia nā ʻano hana hoʻāʻo mīkini e loiloi i nā waiwai mechanical a me ka ikaika o nā hui welded. Aia kekahi mau ʻenehana maʻamau:

• ʻO ka hoʻāʻo ʻana: ʻO ka hoʻāʻo ʻana e pili ana i ka hoʻohana ʻana i ka ikaika tensile i ka hui welded a hiki i ka haki ʻana. Kōkua kēia ho'āʻo e hoʻoholo i ka ikaika tensile hope o ka hui, ka ikaika hāʻawi, a me ka elongation, e hāʻawi ana i nā ʻike i kona kūpaʻa mechanical.
• Ka Ho'āʻo Paʻakikī: E ana ka ho'āʻo paʻakikī i ka paʻakikī o ka hui welded me ka hoʻohanaʻana i nā mea hana kūikawā, e like me ka mea ho'āʻo paʻakikī. Hāʻawi ia i kahi hōʻailona o ka ikaika o ka hui a me ke kū'ē i ka deformation.

4. Ka nānā ʻana i ka hana: ʻae ʻia nā ʻenehana nānā i ke kaʻina no ka loiloi manawa maoli o nā palena wili a me nā hōʻailona maikaʻi i ka wā o ka hana wili. Hoʻohana maʻamau kēia mau ʻenehana i ka hoʻohana ʻana i nā mea ʻike a i ʻole nā ​​​​pūnaewele nānā e hopu a nānā i ka ʻikepili e pili ana i kēia manawa, ka uila, ka mahana, a i ʻole ka ikaika. Hiki i nā haʻalele ʻana mai nā paepae i hoʻopaʻa ʻia a i ʻole nā ​​koho i koho mua ʻia ke hoʻomaka i nā mākaʻikaʻi a i ʻole nā ​​hoʻoponopono ʻakomi e mālama i ka maikaʻi weld.

Pono nā ʻenehana nānā pono kūpono no ka hōʻoia ʻana i ka hilinaʻi a me ka hana ʻana o nā hui welded i hana ʻia e nā mīkini wiliwili wahi inverter medium-frequency. Ma ka hoʻohui ʻana i ka nānā ʻana i nā hiʻohiʻona, nā ʻano hoʻāʻo ʻole luku, ka hoʻāʻo ʻana i ka mīkini, a me ka nānā ʻana i ke kaʻina hana, hiki i nā mea hana ke loiloi piha i ka maikaʻi o nā welds. Hiki i kēia mau ʻenehana ke ʻike mua i nā hemahema, e hōʻoia ana e hiki ke lawe koke ʻia nā hana hoʻoponopono e mālama i nā welds kiʻekiʻe a hoʻokō i nā kūlana i koi ʻia. ʻO ka hoʻokō ʻana i nā ʻenehana nānā maikaʻi maikaʻi e hoʻonui ai i ka pono holoʻokoʻa a me ka pono o nā mīkini wiliwili wahi inverter medium-frequency, alakaʻi.
