Iindidi ezine zensimbi engenasimo kunye nendima yezinto zokwabelana:
Intsimbi engenasimo inokuthi ihlelwe kwiindidi ezine eziphambili: I-Austititic, Martietic, i-Ferric, kunye ne-Deerric, iTheyibhile 1). Olu hlaselo lusekwe kulwakhiwo lwentsimbi engenasimo kubushushu begumbi. Xa i-carbon yekharbon ifudunyele ukuba ifuduselwe ukuya kwi-1550 ° C, utshintsho lwayo lotshintsho ukusuka kwigumbi legumbi-amaqondo obushushu avela kwi-austedite. Ukupholisa, uLwakhiwo lwe-Microsstal ibuyela umva. I-Austedite, ekhoyo kumaqondo obushushu aphezulu, ayingowayi-signetic kwaye inamandla asezantsi kodwa ilanga elingcono lithelekiswa negumbi lobushushu begumbi.
Xa i-chromium (CR) yomxholo kwintsimbi ye-16%, uLWAZI LOKUGQIBELA LWEZIHLOBO LIYABONAKALISA UKUSETYENZISWA KWESIQINISEKISO SESIFUNDO, ugcina ubushushu kuwo onke amaqondo obushushu. Olu hlobo lubizwa ngokuba yintsimbi engenasitali. Xa zombini iChromium (CR) Ingaphezulu kwe-17% kwaye umxholo we-Nickel (NI) ungaphezulu kwe-7%, inqanaba le-Austete lizinzile, ligcina amaqondo obushushu asezantsi ukuya kwindawo enyibilikayo.
Intsimbi engenasimo i-Austetitic Stainess idla ngokubizwa ngokuba ngu "CR-N", ngelixa iMassins Izinto ezikwintsimbi engenasitali kunye ne-Filter Filling zinokuhlelwa ngokwezinto ezenziweyo ze-austedite kunye nezinto ezenza i-ferrita. Izinto ezisisiseko zokwenza i-austerite zibandakanya i-NI, C, MN, kunye no-N, ngelixa izinto zokwenza i-Ferrite ezisebenzisa i-FR,, MO, kunye ne-NB. Ukulungelelanisa umxholo wale nto kunokulawula ubungakanani bofelithe kwi-Weld Jikelele.
Intsimbi engenasimo sengqondo esingenangqondo, ngakumbi xa iqulethe ngaphantsi kwe-5% initrogen (n), kulula ukuyila kwaye ibonelela ngomgangatho ongcono welding othelekiswa neziqu ezingenasiseko. Amalungu e-Austitic angenasitali sensimbi ebonakalisa amandla amnandi kunye nexesha, ahlala ephelisa imfuno yonyango lwelding kunye nonyango lwasemva kweldil. Kwintsimi ye-welding ye-welding yentsimbi engenasimo, i-austetitic stainic inika i-80% yazo zonke izinto zokusetyenziswa kwentsimbi ngaphandle kwentsimbi, zenza ukuba ibe yeyona nto iphambili kweli nqaku.
Ungayikhetha njani ichanekileyoI-Staint yensimbiIzinto ezinokuthethwa, iingcingo kunye nee-electrode?
Ukuba izinto zabazali ziyafana, umthetho wokuqala kukuba "dibanisa izinto zabazali." Umzekelo, ukuba amalahle aqhagamshelwe ukuya kwi-310 okanye i-316 intsimbi engenasibala, khetha izinto ezihambelana netyala. Xa i-welding ye-welding ye-Wildis, landela isikhokelo sokukhetha isixhobo esisisiseko esihambelana nomxholo ophezulu. Umzekelo, xa u-Welding 304 kunye ne-316 intsimbi engenasibala, khetha i-316 yohlobo lwe-welding. Nangona kunjalo, kukho iimeko ezininzi ezikhethekileyo apho umgaqo "ohambelana nesinyithi" awulandelwa. Kule meko, kuyacetyiswa ukuba "ubhekise kwitshathi yokukhetha i-welding.". Umzekelo, uhlobo lwensimbi engama-304 yeyona nto iphambili yeyona nto ixhaphakileyo, kodwa akukho hlobo lwe-rod ye-rod.
Ukuba izinto ezibonakalayo ze-welding zihambelana nentsimbi yesinyithi, indlela yokukhetha umxholo we-welding ukuya kwi-Weld 304 wire yentsimbi engenanto kunye ne-electrode?
Xa i-welding intsimbi engama-304 ye-staight, sebenzisa uhlobo lwe-uplding le-welding kuba izinto ezongeziweyo kwi-308 intsimbi engenasitali ingenazinza ngcono indawo ye-WEMID. I-308l kukhenketho olwamkelekileyo. I-L ibonisa umxholo wekhabhoni esezantsi, i-3xxl stain ibonisa umxholo wekhabhoni we-0.03%, ngelixa i-3xx engenasitali ingena kwi-0.08% yomxholo wekhabhoni. Ukususela kwi-L-Chwetheza i-W-Chwetheza i-Woullings enokuthathwa ukuba iluhlobo olufanayo lokuhlelwa njengezinxibo ze-wilding, abavelisi kufuneka bathathele ingqalelo ukusebenzisa utyekelo lwe-l-yodidi lwe-wilbon lunokunciphisa umkhwa wokunqongophala komntu. Ngapha koko, umbhali ukholelwa ukuba ukuba abavelisi bafuna ukuphucula iimveliso zabo, izixhobo zetyhefu ze-l-etyhefu ziya kusetyenziswa ngokubanzi. Abavelisi abasebenzisa iindlela ze-GMAWW nazo zikwathathela ingqalelo i-3xxsing uhlobo lwentsimbi engenasitali ngenxa yokuba i-SI inokuphucula iindawo ezimanzi kunye nokuvuza. Kwimeko apho isiqwenga se-Coal sinencopho ephezulu okanye unxibelelwano lwechibi le-welding lihlwempuzekile kwi-Wel ye-Wind ye-Angle okanye i-Willing Wires, ukusetyenziswa kwe-Wires, ukusetyenziswa kwe-Widing Wine .
