Welding uye deformation kudzivirira Stainless simbi grating

Nekuenderera mberi kwekuvandudzwa kwepetroleum, makemikari, mishonga uye mamwe maindasitiri, kudiwa kwemidziyo inodzivirira kuora kuri kuwedzera. Mamwe magiya esimbi asina tsvina anoshandiswa zvakanyanya mumabhizinesi emakemikari, kunyanya austenitic simbi isina tsvina, ine yakanaka corrosion resistance uye kugadzikana kwekupisa. Iine maitiro ari kuwedzera mumaindasitiri ekushandisa gore negore. Nekuti ine yakakwira nickel uye ine single-phase austenite chimiro pakamuri tembiricha, ine yakakwira corrosion resistance, high plasticity uye kuomarara pakudzikira tembiricha, tembiricha yekamuri uye tembiricha yepamusoro, pamwe nekunaka kutonhora kuumba uye weldability. 304 simbi isina tsvina ndiyo inonyanya kushandiswa mukugadzirwa kwesimbi.

Hunhu hwe304 simbi isina tsvina
Zvimiro zve304 Stainless steel flat simbi ishoma yekupisa conductivity, ingangoita 1/3 yekabhoni simbi, resistivity kanokwana ka5 iyo yekabhoni simbi, mutsara wekuwedzera coefficient inosvika 50% yakakura kupfuura kabhoni simbi, uye density yakakura kupfuura kabhoni simbi. Stainless steel welding tsvimbo dzinowanzo kupatsanurwa muzvikamu zviviri: acidic calcium titanium mhando uye alkaline yakaderera hydrogen mhando. Low hydrogen Stainless steel welding rods ane yakakwira thermal crack resistance, asi magadzirirwo awo haana kunaka secalcium titanium type welding rods, uye kusaita ngura kwadzo kwakaipa zvakare. Calcium titanium mhando Stainless simbi welding tsvimbo ine yakanaka process performance uye inoshandiswa zvakanyanya mukugadzira. Sezvo Stainless simbi ine akawanda maitiro akasiyana kubva kabhoni simbi, ayo welding process specifications akasiyanawo kubva kabhoni simbi. Stainless simbi gratings ane diki dhigirii kuzvidzora, uye pasi penzvimbo kudziyisa uye kutonhora panguva welding, zvichikonzera kusaenzana kudziyisa uye kutonhora, uye weldments kuchaita kusaenzana kushushikana uye kunetsa. Kana iyo longitudinal kupfupisa weld ichipfuura imwe kukosha, kumanikidza kumucheto kwesimbi grating weldment kunoburitsa yakanyanya kukomba-senge deformation, inokanganisa kutaridzika kwemhando yebasa.

Chengetedzo yewelding simbi isina tsvina gratings
Matanho makuru ekugadzirisa kutsva, kupisa-kuburikidza uye deformation inokonzerwa nesimbi isina tsvina grating welding ndeiyi:
Nyatsodzora kupinza kwekupisa pajoinhi rewelding, uye sarudza nzira dzakakodzera dzewelding uye magadzirirwo paramita (kunyanya welding current, arc voltage, welding speed).
2. Saizi yegungano inofanira kunge yakanyatsojeka, uye gap rekuonana rinofanira kuva diki sezvinobvira. Gomba rakati kurei rinowanzopisa-kuburikidza kana kuumba dambudziko hombe rewelding.
3. Shandisa hardcover fixture kuti uve nechokwadi chakaenzana kuenzanisa clamping simba. Mapoinzi akakosha ekucherechedza kana welding simbi isina simbi gratings: nyatso kudzora simba rekuisa pane welding joint, uye edza kudzikisira kupisa kupinza paunenge uchipedzisa welding, nekudaro kuderedza kupisa-kukanganisa nzvimbo uye kudzivirira kuremara kuri pamusoro.
4. Stainless simbi grating welding iri nyore kushandisa diki kupisa kupinza uye diki ikozvino nekukurumidza welding. Iyo welding wire haizungunuke kumashure uye mberi yakatwasuka, uye weld inofanira kuve yakamanikana pane yakafara, zviri nani kwete inodarika katatu dhayamita yewaya yekubatira. Nenzira iyi, weld inotonhora nekukurumidza uye inogara munzvimbo ine ngozi yekushisa kwenguva pfupi, izvo zvinobatsira kudzivirira intergranular corrosion. Kana iyo yekupisa yekupinza iri diki, iyo welding kushushikana idiki, iyo inobatsira kudzivirira kusagadzikana ngura uye kupisa kwekuputika, uye welding deformation.
