- Kwatanta Amfani da Makamashi:Lokacin walda zanen karfe Q235 masu kauri iri ɗaya, madaidaicin amfani da makamashi guda ɗaya-matsakaicin mita tabo waldashine 180J, yayin da mai walƙiya tsinkaya yana buƙatar 300J (saboda ƙarin makamashi da ake buƙata don rushe hasashen).
- Kudin Kulawa:Spot walda lantarki rayuwa zai iya kaiwa 100,000 waldi (CuCrZr abu), yayin da tsinkaya walda lantarki ne mai saukin kamuwa da nakasu a karkashin babban matsa lamba da kuma bukatar maye gurbin kowane 30,000 welds.
- Lissafin ROI:Ɗaukar layin samarwa tare da fitarwa na shekara-shekara na guda 500,000 a matsayin misali, zabar amatsakaicin mita tabo waldazai iya rage cikakken farashi ta 230,000 CNY / shekara (duba Table 2).
Yiwuwar Haɗin Kan Aiki Automation
- Gudun Amsa:Matsayin 1ms{1}}Imar martani na yanzu na masu walda tabo yana sa su fi dacewa da (haɗin kai) aiki tare da manyan makamai na robotic (Mafi girma ko daidai da 4m/s).
- Rufe Madaidaicin Bayanai:Na zamanimatsakaicin mitar tabo waldana iya sa ido kan juriya mai ƙarfi a cikin ainihin lokaci da hasashen ƙarfin walda ta hanyar algorithms AI, yayin da daidaita tsarin waldawar tsarin walda ya dogara da gwaji{1}}da{2} tabbatar da kuskure.
- Nazarin Harka:Babban kamfani na kayan aikin gida hadeddematsakaicin mitar tabo waldaa cikin tsarin tagwayen dijital, rage sabon lokacin haɓaka aikin walda samfurin daga kwanaki 14 zuwa kwanaki 3.

- Yanke -}irƙirar ƙira:Sabon tsara namatsakaicin mitar tabo waldaYin amfani da na'urorin inverter na silicon carbide (SiC) yana rage yawan kuzari da wani kashi 18% kuma ya tabbatar da ƙimar sa a cikin walƙiya titanium gami da sararin samaniya.
III. Halin da Ba a Maye gurbinsa don Matsakaicin Matsakaici Hasashen Welders
Ko da yakematsakaicin mita tabo waldayana da fa'idodi masu mahimmanci, tsinkaya walda har yanzu suna da ƙima a takamaiman wurare:
- Haɗa Daban-daban Materials tare da Babban Bambancin Kauri
When the thickness ratio of upper and lower workpieces is >1: 4 (misali, walda goro M10 zuwa takardar karfe 3mm), waldawar tsinkaya na iya guje wa huda takardar bakin ciki.
- Magani:Wani babban{0}}matsakaicin mitar tabo waldaiya yanzu rike workpieces tare da 1: 5 kauri rabo ta ƙara matsa lamba na'urorin firikwensin, a hankali encroaching kan tsinkaya walda kasuwar.
- Tsare-tsare na Musamman tare da Matsalolin sararin samaniya
A cikin rufaffiyar sarari kamar ginshiƙan mota A-, ƙirar hanyar shiga wutar lantarki mai gefe guda ɗaya na masu walda tsinkaya suna ba da mafi kyawun aiki.
- Ci gaba da Fasaha: Matsakaicin mitar tabo waldasanye take da na'urorin lantarki na duniya sun karya ta wannan iyakancewar. Misali, masana'antar Tesla ta Shanghai tana amfani da makamai masu sassaucin ra'ayi don cimma matattun digiri 360{2}}waldawar kwana.
IV. Samfuran Zaɓin Zaɓi: Hanya Hudu{{1}Mai Girma
- Kamfanoni ya kamata a kimiyance su zaɓi nau'in kayan aiki bisa ga alamomi masu zuwa:
- Haɗin Abu:Daban-daban / makamantan karafa, tare da ko ba tare da sutura ba.
- Girman Kauri:Kauri rabo na babba da ƙananan workpieces.
- Buƙatar Ƙarfi:Lokacin sake zagayowar aya ɗaya, ƙarar samarwa ta yau da kullun.
- Matsalolin kasafin kuɗi:Siyan kayan aiki da ƙimar farashin O&M.
- Dabarun Nasiha:
Zabi amatsakaicin mita tabo waldasama da 80% na al'amuran gabaɗaya.
- Consider a dedicated projection welder only when the thickness ratio is >1: 5 da workpiece tsarin ba za a iya gyara.
