I-Welding kunye nokuthintela ukuguqulwa kwe-grating yensimbi engenasici

Ngophuhliso oluqhubekayo lwepetroleum, iikhemikhali, amayeza kunye namanye amashishini, imfuno yezixhobo ezinganyangekiyo iyanda. Iigrayiti zensimbi ezingenasici zisetyenziswa ngokubanzi kumashishini ekhemikhali, ngakumbi i-austenitic stainless steel, enokumelana ne-corrosion elungileyo kunye nokuzinza kwe-thermal. Inomkhuba okhulayo kwizicelo zemizi-mveliso unyaka nonyaka. Ngenxa yokuba iqulethe i-nickel ephezulu kwaye ine-single-phase austenite structure kwiqondo lokushisa, inokumelana nokugqwala okuphezulu, iplastiki ephezulu kunye nokuqina kwiqondo lokushisa eliphantsi, ubushushu begumbi kunye nobushushu obuphezulu, kunye nokwenza kakuhle okubandayo kunye ne-weldability. I-304 insimbi engenasici yeyona nto isetyenziswa kakhulu kwimveliso yentsimbi.

Iimpawu ze-304 zensimbi engenasici
Iipropati ze-304 zentsimbi yensimbi engenasici ziphantsi kwe-thermal conductivity, malunga ne-1/3 ye-carbon steel, i-resistiveivity malunga namaxesha ama-5 e-carbon steel, i-coefficient yokwandisa i-linear malunga ne-50% enkulu kune-carbon steel, kunye noxinano olukhulu kune-carbon steel. Iintsimbi zokuwelda intsimbi zidla ngokwahlulahlulwe zibe ziindidi ezimbini: uhlobo lwetitanium calcium acidic kunye nealkaline low hydrogen type. Iintsimbi zokuwelda zentsimbi esezantsi ye-hydrogen zinokumelana nokuqhekeka kwe-thermal ephezulu, kodwa ukubunjwa kwazo akulunganga njenge-calcium titanium yohlobo lwe-welding rods, kwaye ukuxhathisa kwazo kumbi. I-Calcium titanium yodidi lwentsimbi ye-welding yentsimbi inenkqubo efanelekileyo yokusebenza kwaye isetyenziswa ngakumbi kwimveliso. Ekubeni insimbi engenasici ineempawu ezininzi ezahlukileyo kwi-carbon steel, iinkcukacha zayo zenkqubo ye-welding nazo zihluke kwi-carbon steel. Iigridi zensimbi ezingenasici zinezinga elincinci lokuzibamba, kwaye ziphantsi kokufudumala kwendawo kunye nokupholisa ngexesha le-welding, okubangelwa ukufudumeza okungalinganiyo kunye nokupholisa, kunye ne-weldments iya kuvelisa uxinzelelo olungalinganiyo kunye noxinzelelo. Xa i-longitudinal yokunciphisa i-weld idlula ixabiso elithile, uxinzelelo olusemphethweni we-weldment yensimbi iya kuvelisa i-deformation enzulu efana ne-wave, echaphazela umgangatho wenkangeleko ye-workpiece.

Izilumkiso ze-welding steel stainless gratings
Amanyathelo aphambili okusombulula ukutshisa, ukutshisa kunye nokuguqulwa okubangelwa yi-stainless steel grating welding zezi:
Lawula ngokungqongqo igalelo lobushushu kwi-welding joint, kwaye ukhethe iindlela ezifanelekileyo ze-welding kunye neeparitha zenkqubo (ikakhulukazi i-welding current, i-arc voltage, i-welding speed).
2. Ubungakanani bendibano kufuneka buchaneke, kwaye i-gap ye-interface kufuneka ibe yincinci kangangoko kunokwenzeka. Umsantsa othe ukuba mkhulu kancinci uthambekele ekutshisweni okanye wenze ingxaki enkulu ye-welding.
3. Sebenzisa into enoqweqwe oluqinileyo ukuqinisekisa ngokulinganayo amandla okubamba alinganayo. Amanqaku aphambili ekufuneka aqwalaselwe xa udibanisa i-welding steel stainless gratings: lawula ngokungqongqo igalelo lamandla kwi-welding joint, kwaye uzame ukunciphisa igalelo lobushushu ngelixa ugqibezela i-welding, ngaloo ndlela unciphisa indawo echaphazelekayo ukushisa kwaye ugweme iziphene ezingentla.
4. I-stainless steel grating welding kulula ukusebenzisa igalelo lobushushu elincinci kunye ne-welding encinci yangoku ngokukhawuleza. I-welding wire ayijingi ngasemva naphambili ngokuthe tye, kwaye i-weld kufuneka ibe mxinwa kunokuba ibe banzi, ngokuqhelekileyo ingabi ngaphezu kwama-3 ububanzi bocingo lwe-welding. Ngale ndlela, i-weld iphola ngokukhawuleza kwaye ihlale kwiqondo lokushisa eliyingozi ixesha elifutshane, eliluncedo ekuthinteleni ukubola kwe-intergranular. Xa igalelo lobushushu lincinci, uxinzelelo lwe-welding luncinci, olunenzuzo yokuthintela ukubola koxinzelelo kunye nokuqhekeka kwe-thermal, kunye ne-welding deformation.
