UWeld Njani iStainless Steel: Gqibezela iSikhokelo

Intsimbi engatyiwa sisixhobo esisetyenziswa ngokubanzi kuwo wonke amashishini ngenxa yokunganyangeki komhlwa, ukomelela, kunye nenkangeleko ecocekileyo. Nangona kunjalo, i-welding steel stainless idinga iindlela ezithile kunye nezilumkiso zokuqinisekisa umgangatho kunye nokuthembeka kwesakhiwo. Esi sikhokelo siya kukuhamba ngeziseko zendlela yokuwelda intsimbi engatyiwayo, ezona ndlela zibalaseleyo, kunye neengcebiso zokuthintela imiba eqhelekileyo.

Kutheni iWelding iStainless Steel yahlukile

Insimbi engenasici yahlukile kwi-carbon steel kunye ne-aluminium xa kuziwa kwi-welding. I-chromium ephezulu kunye nomxholo we-nickel yenza ukuba ikwazi ukuxhathisa ukubola, kodwa iphinde ibe buthathaka ngakumbi kubushushu. I-welding engafanelekanga inokubangela i-warping, i-carbide precipitation, okanye ilahleko yokuxhathisa ukubola.

Ukukhetha inkqubo echanekileyo kunye nezinto zokuzalisa kubalulekile ukugcina ingqibelelo ye-welded joint kunye nokuqinisekisa ukuba inxalenye igcina iimpawu zayo ezingenasici.

Iindidi eziqhelekileyo zeNtsimbi yeStainless ye-Welding

Phambi kokuwelding, kubalulekile ukuchonga ibakala lentsimbi engatyiwayo osebenza nayo:

• I-Austenitic (umz., 304, 316):Ubukhulu becala obudityanisiweyo, obugqwesileyo bokumelana nomhlwa

• IFerritic (umz., 430):Iindleko eziphantsi, ukuwelda okulinganiselweyo

• IMartensitic (umz., 410):Kunzima kodwa kulula ukuqhekeka

• I-Duplex (umz., 2205):Inamandla kunye ne-corrosion-resistant, kodwa ifuna iinkqubo ze-welding ezilawulwayo

At sakysteel, sinika uluhlu olubanzi lwezinto zensimbi ezingenasici-kuquka i-304, i-316, kunye ne-duplex amabakala-elungele ukwenziwa kunye ne-welding.

Iindlela zokuWelding ezigqwesileyo zeNtsimbi eNgatyiwayo

Kukho iindlela ezininzi ze-welding ezifanelekileyo kwintsimbi engenasici. Ukukhetha kwakho kuxhomekeke kubukhulu, usetyenziso, kunye nokufumaneka kwezixhobo.

1. TIG Welding (GTAW)

I-Tungsten Inert Gas (TIG) welding yeyona ndlela ichanekileyo. Inika iiwelds ezicocekileyo, ezinamandla kunye nesitshizi esincinci.

Igqibelele:Amaphepha entsimbi acwebileyo kunye ne-aesthetics ecocekileyo
Irhasi yokukhusela:100% Argon okanye Argon / Helium mix
Intonga yokugcwalisa:Kufuneka ihambelane nesiseko sentsimbi (umz.,I-ER308Lku304)

2. I-MIG Welding (GMAW)

Ukuwelda kwe-MIG kuyakhawuleza kwaye kulula ukuyifunda kune-TIG, kodwa kusenokungabi coceki kangako okanye kuneenkcukacha.

Igqibelele:Amacandelo atyebileyo kunye nemveliso enkulu
Irhasi yokukhusela:I-Argon ene-CO₂ okanye i-oxygen yozinzo olungcono lwe-arc
ucingo:Sebenzisa ucingo lwentsimbi engatyiwa (umz., ER316L,I-ER308)

3. Intonga yokuWelding (SMAW)

Ukuwelda ngentonga kuxolela ngakumbi kwiindawo ezimdaka nakwiimeko zangaphandle.

Igqibelele:Umsebenzi wokulungisa nowokulungisa
Ii-Electrodes: E308L, E309L, okanye E316L kuxhomekeke kwisiseko sesinyithi

Iingcebiso zokulungiselela phambi kwe-Welding

Ukulungiswa okufanelekileyo ngundoqo ekuphumezeni i-weld ecocekileyo, engenasiphako:

• Coca umphezulu:Susa ioli, umhlwa, ubumdaka, kunye ne-oxide layers

• Sebenzisa izixhobo ezikhethekileyo:Kuphephe ukungcoliseka ngokunqamlezayo ngezixhobo zentsimbi yekhabhoni

• Tack welds:Sebenzisa i-welds ye-tack ukubamba iinxalenye endaweni kunye nokunciphisa ukuphazamiseka

• Ukucoca ngasemva:Ngombhobho okanye i-tube welding, ukucocwa ngasemva ngegesi engasebenziyo kunokuthintela i-oxidation kwindawo engaphantsi kwe-weld.

Ukunqanda iziphene zeWelding eqhelekileyo

Eminye yemiba exhaphakileyo xa uwelda intsimbi engenastainless ibandakanya:

• Ukuqhekeka:Ngokuqhelekileyo ngenxa yobushushu obuninzi okanye imathiriyeli yesihluzi esingachanekanga

• Uphazanyiso:Ibangelwa kukufakwa kobushushu obuphezulu kunye nokulungiswa kakubi

• Ukonakala kwindawo yeweld:Ngenxa yokhuselo olungafanelekanga okanye ilahleko yechromium ngexesha lewelding

• I-Sugaring (i-oxidation):Ukuba ayikhuselwanga ngokufanelekileyo, ingaphakathi le-weld linokwenza i-oxidize

Ukuthintela oku, sebenzisa igalelo lobushushu elilawulwayo, ukukhusela igesi okuchanekileyo, kunye nokucoca emva kwe-weld apho kuyimfuneko.

Ukucocwa kwe-Post-Weld kunye ne-Passivation

Emva kwe-welding, insimbi engenasici ihlala ifuna ukucocwa ukubuyisela ukuxhathisa umhlwa:

• UkukhaUkusebenzisa isisombululo se-asidi ukususa i-tint yobushushu kunye ne-oxide layers

• Ukunyusa:Yongeza umaleko we-chromium oxide yendalo ukuze uxhathise ngcono umhlwa

• Ukugulisa oomatshini:Igudisa kwaye iqaqambise umphezulu wezicelo zococeko

sakysteelicebisa ukuba isoloko ivavanya iimfuno zomphezulu wokugqiba ngokuxhomekeke kokusingqongileyo-ingakumbi kudidi lokutya okanye ukusetyenziswa kwaselwandle.

Iingcamango Zokugqibela

I-Welding steel stainless inokuba nzima ngakumbi kunezinye isinyithi, kodwa ngolwazi oluchanekileyo, izixhobo kunye nokulungiselela, unokufikelela kumalungu aqinileyo, anganyamekiyo ukubola ahlala iminyaka. Nokuba wakha iinqanawa zoxinzelelo, izixhobo zokutya, okanye izinto ezakhiweyo, ukuqonda inkqubo ye-welding kubalulekile.

At sakysteel, asinikezeli kuphela umgangatho ophezulu weentsimbi, imibhobho, kunye namashidi-sikwaxhasa inkqubo yakho yokwenza izinto kunye neenkcukacha zobugcisa kunye nomgangatho wemveliso ongaguqukiyo. Qhagamshelana nathi namhlanje ngeenkcukacha ezithe kratya okanye ukufumana iingcebiso eziphathekayo ezilungiselelwe iprojekthi yakho ye-welding.
