Aluminium alloy welding yakasiyana zvakanyanya kubva kune yakajairwa kabhoni simbi, Stainless simbi uye zvimwe zvinhu. Zviri nyore kugadzira kukanganisa kwakawanda kusina zvimwe zvinhu, uye matanho anonangwa anofanira kutorwa kuti azvidzivirire. Ngatitarisei matambudziko ari nyore kuitika mualuminium alloy welding uye zvinodiwa zvekugadzira tekinoroji.
Kuomerwa muwelding aluminium alloy materials Thermal conductivity yealuminium alloy materials is 1 kusvika 3 times yakakura kudarika yesimbi, uye zviri nyore kupisa. Zvisinei, nyaya iyi haigoni kupikisa kutonhora kwepamusoro uye ine coefficient yakakura yekuwedzera kana ichipisa, iyo inokonzeresa nyore kugadzirisa welding. Uyezve, chinhu ichi chinowanzoita kutsemuka uye kupinza weld panguva yewelding, kunyanya kupisa kwemahwendefa ealuminium matete kunonyanya kuoma.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Aluminium alloy welding inoburitsa imwe huwandu hwehydrogen mudziva rakanyungudutswa. Kana magasi aya asina kusunungurwa kusati kwaitwa weld, inokonzera pores mu weld uye inokanganisa kunaka kwezvikamu zvakasungirirwa.
Aluminium isimbi inogadziriswa oxidized nyore, uye mumhepo inenge isina unoxidized aluminium. Kana pamusoro peiyo aruminiyamu alloy yakanyatso kuratidzwa kumhepo, dense uye insoluble aluminium oxide firimu inoumbwa pamusoro payo. Iyo oxide firimu inonyatso kupfekwa uye inodzivirira kupisa kwepamusoro, ine nzvimbo yekunyungudika inopfuura 2000 degrees Celsius. Kana yangoumbwa, iyo inotevera yekuomerwa kwekugadzirisa ichawedzerwa zvakanyanya.
Aluminium alloy welding inewo matambudziko akadai sekuti majoini ari nyore kupfava, uye kusawirirana kwepamusoro munzvimbo yakanyungudutswa kudiki uye kuri nyore kugadzira kukanganisa.
Zvinodiwa zvealuminium alloy welding process
Chekutanga pane zvese, kubva pamaonero emidziyo yewelding, kana MIG/MAG welding muchina wakashandiswa, unofanirwa kunge uine pulse mabasa senge puruse imwechete kana kaviri pulse. Iyo kaviri pulse function ine yakanakisa mhedzisiro. Kaviri pulse ndiyo yepamusoro-frequency pulse uye low-frequency pulse, uye low-frequency pulse inoshandiswa kugadzirisa high-frequency pulse. Nenzira iyi, iyo kaviri pulse ikozvino inogadziriswa pahuwandu hwepasi-frequency pulse kuti nguva nenguva ishanduke pakati pepamusoro-soro uye nheyo yezvino, kuitira kuti weld iite zviyero zvehove nguva dzose.
Kana iwe uchida kushandura maitiro ekugadzira weld, unogona kugadzirisa frequency uye peak kukosha kweiyo yakaderera-frequency pulse. Kugadzirisa iyo yakaderera-frequency pulse frequency ichakanganisa kukurumidza kwekuchinja pakati pepamusoro kukosha uye kukosha kwepasi kwekaviri pulse ikozvino, izvo zvinozoshandura kupatsanurwa kwehove sikero patani ye weld. Kunyanya kumhanya kwekuchinja, kudiki kudiki kwepakati petani yechiyero chehove. Kugadzirisa kukosha kwepamusoro-yepasi-frequency pulse kunogona kushandura mhepo inomutsa padziva rakanyungudutswa, nekudaro ichichinja kudzika kwewelding. Kusarudza yakafanira peak kukosha kune zviri pachena mhedzisiro yekudzikisa chizvarwa chepores, kuderedza kupisa kwekuisa, kudzivirira kuwedzera uye deformation, nekuvandudza weld simba.
Uye zvakare, kubva pakuona kweiyo welding process, zvinotevera zvinhu zvinofanirwa kucherechedzwa:
Kutanga, pamusoro pearuminiyamu alloy inofanira kucheneswa isati yanyungudutswa, uye guruva rose nemafuta zvinofanira kubviswa. Acetone inogona kushandiswa kuchenesa pamusoro peiyo aluminium alloy welding point. Kune gobvu ndiro aruminiyamu alloy, inofanira kucheneswa newaya bhurasho kutanga, uye ipapo neacetone.
Chechipiri, iyo welding wire material inoshandiswa inofanira kunge iri pedyo nemubereki zvinhu sezvinobvira. Kana yekusarudza aruminiyamu nesilicon welding waya kana aruminiyamu magnesium welding waya inofanira kutariswa zvinoenderana nezvinodiwa zveweld. Uye zvakare, aruminiyamu magnesium welding waya inogona chete kushandiswa kuchinjisa aruminiyamu magnesium zvinhu, nepo aruminiyamu nesilicon welding waya iri kunyanya kushandiswa zvakanyanya. Inogona weld aluminium silicon zvinhu uye aluminium magnesium zvinhu.
Chechitatu, kana kukora kwendiro kwakakura, ndiro yacho inofanira kunge yakafanopisa, kana zvisina kudaro zviri nyore kupinza. Paunenge uchivhara arc, ikozvino duku inofanira kushandiswa kuvhara arc uye kuzadza gomba.
Chechina, paunenge uchiita tungsten inert gasi arc welding, DC argon arc welding muchina unofanirwa kushandiswa, uye kumberi nekumashure AC uye DC inofanira kushandiswa zvakachinjana. Forward DC inoshandiswa kuchenesa pamusoro oxidation mold yearuminiyamu zvinhu, uye reverse DC inoshandiswa pakugadzira.
Uyewo cherechedza kuti welding tsanangudzo inofanira kuiswa maererano neplate ukobvu uye weld zvinodiwa; MIG welding inofanira kushandisa yakakosha aruminiyamu waya yekudyisa vhiri uye Teflon waya yekutungamira chubhu, zvikasadaro machipisi ealuminium anogadzirwa; iyo welding pfuti tambo haifanirwe kunge yakareba, sezvo aluminium welding wire yakapfava uye yakarebesa welding pfuti tambo ichakanganisa waya yekudyisa kugadzikana.
