Musiyano pakati pe Overlay Welding uye Hard Facing

Overlay welding uye yakaoma yakatarisana nzira mbiri dzinowanzo shandiswa muindasitiri yekuvandudza kusimba uye kupfeka kuramba kwezvikamu zviri pasi pemamiriro ekushanda akaomarara. Nepo ese ari maviri maitiro aine chinangwa chekusimudzira pamusoro pezvinhu zvechinhu, pane akasiyana akasiyana mukushandisa kwavo, zvinhu zvinoshandiswa, uye zvinokonzeresa zvivakwa. Muchinyorwa chino, isu tichaongorora mutsauko pakati pekuwatira welding uye yakaoma yakatarisana maererano nemaitiro, zviwanikwa, uye zvazvakanakira uye zvisingakwanisi.

Chii chinonzi Overlay Welding

Overlay welding, inozivikanwawo seyakavharika kana kukwirisa, inosanganisira kuisa mutsetse wezvinhu zvinowirirana pamusoro pesimbi yepasi. Izvi zvinowanikwa kuburikidza nemaitiro akadai seakadzika arc welding (SAW), gas metal arc welding (GMAW), kana plasma transfer arc welding (PTAW). Iyo yakafukidzira zvinhu inosarudzwa zvichienderana nekuenderana kwayo nesimbi yepasi uye inodiwa pamusoro pezvinhu.

Zvishandiso Zvinoshandiswa MuOverlay Welding:

1. Weld Overlay: Muhunyanzvi uhu, iyo overlay material inowanzova weld filler metal, inogona kunge iri low-carbon steel, stainless steel, kana nickel-based alloy. Iyo weld overlay zvinhu inosarudzwa zvichibva pakuramba kwayo kutu, kupfeka kuramba, kana kutonhora kwakanyanya.

Zvakanakira zve Overlay Welding:

1. Versatility: Overlay welding inobvumira huwandu hwakawanda hwezvinhu kuti zvishandiswe pakugadziriswa kwepamusoro, zvichipa kuchinjika mukugadzirisa zvinhu zvakafukidzira zvinoenderana nezvinodiwa chaizvo.

2. Inodhura-Inoshanda: Overlay welding inopa mhinduro inodhura yekuvandudza nzvimbo yepamusoro yezvikamu, sezvo chete chidimbu chakaonda chezvinhu zvinodhura chinoshandiswa pasimbi yepasi.

3. Kugadzirisa Kugona: Overlay welding inogona kushandiswawo kugadzirisa nzvimbo dzakakuvadzwa kana dzakasakara, kuwedzera hupenyu hwebasa rezvikamu.

Kuganhurirwa kweOverlay Welding:

1. Bond Strength: Kusimba kwechisungo pakati pezvinhu zvakafukidzirwa uye nheyo yesimbi inogona kunetsa, sezvo kusakwana kusungirirwa kunogona kukonzera delamination kana kukundikana nguva isati yakwana.

2. Hukobvu Hushoma: Welding yekuturikidzana inowanzoganhurwa kumamirimita mashoma ehukobvu, zvichiita kuti isanyanyokodzera maapplication anoda akakora akaturikidzana ezvivakwa zvakawedzerwa.

3. Nzvimbo Inobatwa Nekupisa (HAZ): Kupisa kunopisa panguva yekuputira welding kunogona kutungamirira kukugadzirwa kwenzvimbo inopisa, iyo inogona kuratidza zvinhu zvakasiyana-siyana pane zvakaputirwa uye zvigadziko.

Chii chinonzi Hard Facing

Kutarisa kwakaoma, kunozivikanwawo sekuoma kwepamusoro-soro kana kuvaka-up welding, kunosanganisira kuisa chivharo chinodzivirira kupfeka pamusoro pechinhu kuti chigadzirise kuramba kwayo kubrasion, kukukurwa, uye kukanganisa. Iyi tekinoroji inonyanya kushandiswa kana iyo yekutanga kunetsekana kuri kupfeka kuramba.

Zvishandiso Zvinoshandiswa Mukuoma Kutarisana:

1. Zvigadzirwa Zvakaoma-Kutarisana: Zvishandiso zvakaomeswa zvinyoro zvinowanzove nesimbi yepasi (yakadai sesimbi) uye zvinhu zvinosanganiswa zvakadai sechromium, molybdenum, tungsten, kana vanadium. Aya ma alloys anosarudzwa nekuda kwekuomarara kwawo kwakasarudzika uye kupfeka kuramba.

Zvakanakira Kutarisana Nekuoma:

1. Superior Hardness: Zvinhu zvakaomesesa zvinosarudzwa nokuda kwekuoma kwavo kunoshamisa, izvo zvinobvumira zvikamu kuti zvigadzirise kupfeka kweabrasive, kukanganisa, uye kushandiswa kwepamusoro-kushungurudzika.

2. Pfeka Resistance: Kutarisana kwakaoma kunonatsiridza zvakanyanya kupfeka kwepamusoro, kuwedzera hupenyu hwebasa rezvikamu mumamiriro ekushanda akaomarara.

3. Ukobvu Sarudzo: Kutarisa kwakaoma kunogona kuiswa muzvikamu zvehukobvu hwakasiyana, zvichibvumira kutonga kwakanyatso pamusoro pehuwandu hwezvinhu zvinopfekwa zvinowedzerwa.

Zvinogumira Pakutarisana Nekuoma:

1. Kusiyana-siyana kwakaganhurirwa: Zvishandiso zvakaomarara zvakanangidzirwa pakusapfeka uye zvinogona kunge zviine zvinodikanwa zvinoramba kuita ngura, kutonhora kwakanyanya, kana humwe hunhu hunodiwa mune mamwe maapplication.

2. Mutengo: Zvikamu zvakaomesesa zvinogara zvichidhura kana zvichienzaniswa nepamusoro-soro welding zvinhu, zvingangowedzera mutengo wekugadziriswa kwepasi.

3. Kugadzirisa Kuoma: Kana imwe nguva yakaoma-yakatarisana yakagadziriswa, inogona kuva yakaoma kugadzirisa kana kushandura nzvimbo, sezvo kuoma kwepamusoro kwezvinhu kunoita kuti isanyanya kusungirirwa.

Mhedziso:

Kuwedzeredza welding uye kuomarara kutarisana ndiwo akasiyana maitiro ekugadzirisa epamusoro anoshandiswa kusimudzira kupfeka kuramba uye kusimba kwezvikamu. Kuwedzeredza welding inopa kuita kwakasiyana-siyana uye kudhura-kushanda, kubvumidza kune dzakasiyana siyana sarudzo mune zvakapfuura zvinhu. Inokodzera maapplication anoda corrosion resistance, kupfeka kuramba, kana kuvandudzwa kwepamusoro-tembiricha zvivakwa. Kusiyana neizvi, kuoma-kutarisana kunotarisa kunyanya pakuramba kupfeka, kushandisa alloys nekuoma kwakasiyana. Yakanakira zvikumbiro zvakaiswa mukukuvadzwa kukuru, kukukurwa, uye kukanganisa. Kunzwisisa zvinodikanwa zvechishandiso uye chinodikanwa chepamusoro zvivakwa zvakakosha pakusarudza nzira yakakodzera yekuwana mhedzisiro inodiwa.
