I ka hana ʻenehana, pili pono ka maikaʻi o ka welding i ka hana huahana a me ke ola.Mea Welder Spot Inverter Medium Frequencyhoʻohana nui ʻia ma muli o ko lākou hiki ke hoʻopaʻa paʻa a paʻa, akā inā kūpono ke ʻano metallographic o ka hui welded e koi mau ana i ka hōʻoia ma o ka nānā ʻana i ka ʻoihana. Hoʻopili kēia ʻatikala i nā kumu nui o ka nānā ʻana i ka metallographic no nā welds i hana ʻia e Medium Frequency Inverter Spot Welders.
1. Nā Pahuhopu Koʻikoʻi o ka Nānā Metallographic
Manaʻo ka nānā ʻana i ka metallographic e loiloi i ka microstructure, ka hāʻawi ʻana i ka palaoa, a me nā hemahema i ka wahi welding. No Medium Frequency Inverter Spot Welders, kā lākou mau hiʻohiʻona wili (e laʻa, wahi wela liʻiliʻi -pili ʻia, ikehu koʻikoʻi) e kuhikuhi pono i ka nānā ʻana i nā hōʻailona penei:
- ʻO ka Degere Hoʻomaʻemaʻe ʻana i ka palaoa ma ka ʻāpana Nugget: Loaʻa i nā Welders Spot Inverter Medium Frequency i ka hoʻomehana wikiwiki ma o 1000Hz inverter current. Hoʻohana maʻamau ka nui o ka palaoa Nugget ma waena o 5-15μm, ʻoi aku ka maikaʻi ma mua o ka 20-30μm o ka kuʻuna AC kuʻuna, e hōʻemi ana i ka pilikia embrittlement.
- Wela -Pāhia ʻĀpana: ʻAʻole ʻoi aku ka nui o ka HAZ o nā mea welder kikoʻī ʻo Medium Frequency Inverter Spot Welders i ka 0.5mm. Pono ka nānā ʻana i ka microscopic no ka nānā ʻana i ka oxidation palena o ka palaoa a i ʻole ke ahi.
- Weld Joint Strength: E hōʻoia ma o ka hoʻāʻo tensile inā ʻoi aku ka ikaika o ka weld shear ma luna o 80% o ke kumu waiwai o ka mea.
2. Nā ʻanuʻu koʻikoʻi i ka nānā ʻana i ka metallographic
- Hoʻomākaukau Laʻana: Ma hope o ka laʻana, pono e kau ʻia ka hui welded, lepo, a hoʻomaʻamaʻa ʻia e hōʻoia i ka ʻili ʻole-ili.
- Ka Mākaʻikaʻi Mākaʻikaʻi: E hoʻohana i kahi microscope metallographic ma ka hoʻonui 100-500x no ka nānā ʻana i ka morphology palaoa i loko o ka ʻāpana nugget, kahi i hoʻopili ʻia i ka wela, a me ka metala kumu. No ka laʻana, pono e hōʻike i nā hua ʻai like ʻole me ka ʻole o nā māwae nui a i ʻole nā pores.
- Ke kiʻi ʻana a me ka nānā ʻana: E hoʻohana i ka etching electrolytic e hōʻike i nā palena o ka palaoa a nānā hou aku i ka pono o ka hoʻomaʻemaʻe palaoa. Ua hōʻike ʻia nā hoʻāʻo ʻana e kahi mea hana ʻāpana kaʻa he 304 mau mea weld weld nuggets mai kahi Medium Frequency Inverter Spot Welder i loaʻa i ka 95% ka nui o ka palaoa, ʻoi aku ka maikaʻi ma mua o nā lako kahiko.
3. Hōʻoiaʻiʻo o nā pono ʻenehana o Medium Frequency Inverter Spot Welders
- Hoʻomalu Wela Kūleʻa: Hoʻohana ka poʻe Welders Spot Inverter Medium Frequency Inverter Spot Welders kiʻekiʻe -frequency discharge pulse (0.1-0.3 kekona) no ka hoʻokaʻawale ʻana i ka wela ma ka ʻāpana weld, e hōʻemi ana i ka coarsening palaoa ma muli o ka wela nui o ka metala kumu.
- Hoʻololi i ka ʻāpana naʻauao: -nā mea ʻike i kūkulu ʻia e nānā i kēia manawa a me ke kaomi ʻana i ka manawa maoli, e pale ana i nā hemahema i hoʻokumu ʻia e ka loli ʻana o nā ʻāpana i ka wā wili. No ka laʻana, i ka wā e wili ai i ka alumini alumini, hiki i ka Medium Frequency Inverter Spot Welder ke hoʻomalu i ka nui o ka spatter ma lalo o 1%.
- Paʻa Kaʻina Hana: ʻO ka hoʻolālā modular a me nā ʻōnaehana hoʻomaha maikaʻi (ea + wai) e hōʻoia i ka kūlike o ka weld maikaʻi ma mua o 98% i ka wā lōʻihi o ka hana.
4. Nānā Hiʻohiʻona ma ka hoʻohana pono
Ua hoʻohana kekahi hui ʻoihana uila hou i kahi Medium Frequency Inverter Spot Welder no ka hoʻopili ʻana i ka pā. Ua hōʻike ʻia nā hopena nānā metallographic:
- ʻO 0.45mm ka laula o ka wela weld -pili, e kūpono ana i nā kūlana o ka ʻoihana (emi a i ʻole like me 0.6mm).
- ʻO ka ikaika weld shear i nā hoʻāʻo tensile i hiki i 250MPa, ʻoi aku ka nui o nā koi hoʻolālā (ʻoi aku ma mua o a i ʻole like me 200MPa).
- ʻO 2 wale nō o 1000 mau mea hoʻohālike i loaʻa ka porosity liʻiliʻi, e hāʻawi ana i ka helu pass o 99.8%.
Ka hopena
Ma o ka -frequency kiʻekiʻe a me ka ʻenehana hoʻomalu naʻauao,Mea Welder Spot Inverter Medium Frequencyhoʻomaikaʻi nui i ka maikaʻi microscopic o nā hui welded. ʻO ka nānā ʻana i ka metallographic ʻaʻole ia he hōʻoia o ke kaʻina hana welding akā he loulou nui hoʻi i ka hōʻoia ʻana i ka hilinaʻi o ka huahana. Ma lalo o ke ʻano o ka hana akamai, ʻo ka haku ʻana i nā ʻano loiloi metallographic no ka Medium Frequency Inverter Spot Welder welds e lilo i mea koʻikoʻi no nā ʻoihana e hoʻokō i nā kaʻina hana welding a hoʻonui i ka hoʻokūkū.
