I-valve yesango impahla eluhlaza yensimbi engagqwali induku yokushisela

I-valve yesango impahla eluhlaza yensimbi engagqwali ipuleti lokushisela induku Lokhu okujwayelekile kwepuleti lensimbi yokushisela induku yokuhlukanisa, izindinganiso zobuchwepheshe, izindlela zokuhlola namazinga okuhlola nolunye ulwazi oluhlobene. Leli zinga lisebenza ku-electrode yensimbi engagqwali ye-arc welding. I-electrode cladding metal enjalo kufanele iqukathe ngaphezu kuka-10.50% we-chromium nensimbi eningi kunanoma iyiphi i-elementi. Ngokusho kokwakhiwa kwensimbi ehlanganisiwe, uhlobo lwe-welding core, isikhundla sokushisela kanye nohlobo lwamanje lokushisela, induku yokushisela akufanele ibe namaphutha njengokuqhekeka, amabhamuza, izinsalela kanye nokuwa kuleyo khwalithi yokushisela elimazayo, njengoba kuboniswe kuThebula 1 kanye neThebula. 2. 1. Umbono wetimu kanye nenkambu yesicelo Lesi sigaba sokucaciswa kwenduku yensimbi engagqwali yensimbi engagqwali, izindinganiso zobuchwepheshe, izindlela zokuhlola kanye namazinga okuhlola kanye nolunye ulwazi oluhlobene. Leli zinga lisebenza ku-electrode yensimbi engagqwali ye-arc welding. I-electrode cladding metal enjalo kufanele iqukathe ngaphezu kuka-10.50% we-chromium nensimbi eningi kunanoma iyiphi i-elementi. 2 Amazinga Okuyisethenjwa GB223.1 ~ 223.70 Izindlela zokuhlaziya amakhemikhali ensimbi ne-aluminium alloys GB1954 - Ukukalwa kokuqukethwe kwe-microstructure ekushiseleni i-chrome-nickel low alloy steel GB2652 Indlela yokuhlola eqinile yokushisela nokuhlanganisa insimbi engu-GB 4334.5 yokuhlolwa kwensimbi engagqwali - indlela ye-sodium thiosulfate hydrochloride 3 Uhlobo kanye nezigaba zokucaciswa 3.1 Uhlobo kanye nokucaciswa kwenduku yokushisela kufanele kuhlukaniswe ngokubunjwa kwensimbi ehlanganisiwe, uhlobo lwe-welding core, indawo yokushisela kanye nohlobo lwamanje lokushisela. 3.2 Indlela yokulungiselela Ukucaciswa Kwemodeli Uhlamvu "E" lubonisa i-electrode, futhi inombolo ngemva kuka-"E" imele inombolo yokuhlukaniswa kwengxenye yensimbi encibilikisiwe. Uma kunesidingo esikhethekile sengxenye, ingxenye iboniswa uphawu lwekhemikhali ngemva kwenombolo. Izinombolo ezimbili ngemva kwe "eyodwa" zimelela uhlobo lwe-electrode core, isikhundla se-welding kanye nohlobo lwamanje lwe-welding. 3.3 Izibonelo zokucaciswa kwenduku yokushisela kuleli zinga zimi kanje: ④E502, E505, E7Cr, E5Mo, E9Mo uhlobo lwe-electrode luzofakwa kokujwayelekile okuguquliwe okulandelayo kwe-GB5118 "i-high alloy Steel electrode", kodwa isuswe kuleli zinga. ⑤ Isijobelelo sokuqala XX. Ikhombisa eyodwa 15, eyodwa 16, eyodwa 17, eyodwa 25 noma eyodwa 26. Qaphela: Ukushisela indawo egcwele akunconywa ama-electrode anobubanzi obulingana nangaphezulu kuka-5.0mm. 4 Amazinga Obuchwepheshe 4.1 Imininingwane 4.1.1 Ukucaciswa kwe-electrode kuzohlangabezana nezidingo ezikuThebula 3. 4.1.1.1 Vumela ukukhiqizwa kwe-electrode engu-3.0mm esikhundleni se-electrode engu-3.2 kanye ne-electrode engu-5.8mm esikhundleni se-electrode engu-6.0rnm. 4.1.1.2 Izinduku zokushisela zezinye izichasiselo zivunyelwe ukuba zilethwe ngokwesivumelwano phakathi kweQembu A neQembu B. 4.1.2 Ubude bokuphela kokunamathisela kwe-electrode buyohlangabezana nezidingo ezikuThebula 4. Ithebula 4 Ubude bokuphela kokuhlanganisa. 4.2 I-Welding Core 4.2.1 Akufanele kube nokuqhekeka, amabhamuza, izinsalela kanye nokuwa kumongo wokushisela we-electrode okulimaza ikhwalithi ye-weld. 4.2.2 I-welding core ekupheleni kwe-arc yokuqala ye-electrode kufanele ibe yindilinga, futhi imbobo ye-welding core kufanele ivezwe ukuze kuqinisekiswe ukuthi ukuqala kwe-arc kulula.

Efomini :T1 -- induku yokushisela ingxenye ephambanayo yokufaka ungqimba ** indawo enkulu yokushisela ewugqinsi ewugqinsi T2 -- indawo encane yokushisela ewumgogodla wengxenye ephambanayo ye-epidermal layer 4.3 T-joint weld 4.3.1 Indawo yokushisela kufanele zihlolwe ngamehlo omuntu ngaphandle kwemifantu, izibazi zokushisela, izimbobo zokushisela kanye nezimbobo zomoya. 4.3.2 Ingxenye eyisiphambano ye-weld izohlangabezana nalezi zidingo ezilandelayo ngemva kokupholishwa nokushumeka: a, i-weld ngayinye eseceleni izohlanganiswa noma ngokudlula lapho kuhlangana amapuleti amabili; b. Usayizi wonyawo lwe-weld ohlangothini ngalunye kanye nomehluko phakathi kobude bezimbobo zokushisela ezimbili kufanele uhambisane nezicaciso eziseThebulani lesi-5 (njengoba kukhonjisiwe kuMfanekiso 2). c. I-convexity yephrofayili ngayinye izohlangabezana nezidingo ezikuMdwebo 3. d. Bheka ngamehlo omuntu, akufanele kube nemifantu engxenyeni yesiphambano se-weld. e. Azikho izimbobo zokushisela noma izimbobo zomoya. 4.4 Ukwakheka kwensimbi encibilikisiwe Ukwakheka kwamakhemikhali ensimbi ye-cautery kufanele kuhambisane nezidingo zeThebula 1. 4.5 Izakhiwo ezibonakalayo zokuhlanganisa insimbi Imiphumela yokuhlola eqinile yensimbi ehlanganisiwe kufanele ihambisane nezidingo ezikuThebula 6. Ithebula 6 Izakhiwo ezibonakalayo zokugqunywa kwensimbi Ukuqina kwensimbi iyaxazululwa, kulandele ukupholisa komoya ezingeni lokushisa legumbi. f. Isampula ligqunywe ku-740 ~ 760℃ amahora angu-4, kulandelwa ukupholisa komoya. g. Isampuli yafakwa intuba ku-730~750℃ amahora angu-4, kulandele ukupholisa komoya. 4.6 Ukumelana nokugqwala kwensimbi ehlanganisiwe Ukuhlola ukumelana nokugqwala kwensimbi ehlanganisiwe kuzocaciswa ngesivumelwano sezinhlangothi zombili. 4.7 Okuqukethwe kwesakhiwo se-metallographic sensimbi ehlanganisiwe Okuqukethwe kwe-ferritic kwensimbi ehlanganisiwe kuzocaciswa esivumelwaneni phakathi kweQembu A neQembu B. I-electrode yepuleti lensimbi engagqwali lempahla eluhlaza yevalvu yesango (2) Ukuhlolwa kwezinga le-electrode lohlobo ngalunye kanye nokucaciswa kufanele hambisana nezidingo zeThebula 7. Ngaphambi kokuhlolwa, i-electrode kufanele ibhakwe ngokuhambisana nezinga lokushisa lokumisa elethulwe umenzi. Ifanele ukuxhumana kwe-AC noma ukuhlolwa kwe-DC welding electrode ukukhetha ukuxhumana kwe-AC. Izinto eziyisisekelo ezisetshenziselwa ukuhlaziya ukwakheka kwamakhemikhali kungaba yinsimbi ye-carbon, insimbi ye-alloy ephezulu noma ipuleti lensimbi engagqwali. Okuqukethwe kwekhabhoni yensimbi ehlanganisiwe akumele kudlule u-0.04% we-electrode kanye nesisekelo sezinto ezisetshenziselwa ukuhlaziya ukwakheka kwamakhemikhali e-electrode ye-E63O inekhabhoni ephezulu kakhulu engu-0.03%. Ngokuhambisana nezinhlinzeko ze-athikili 5.4.3, izinto eziyisisekelo ezinokuqukethwe kwekhabhoni ephezulu kakhulu okungu-0.25% nazo zingasetshenziswa. Isisekelo sensimbi yokuhlaziya ukwakheka kwamakhemikhali e-electrode iphezulu kakhulu ikhabhoni engu-0.25%... Ukuxhuma: Insimbi engagqwali yensimbi yokushisela insimbi ye-valve yesango impahla eluhlaza (1) 5 Indlela Yokuhlola 5.1 Ukuhlolwa kwezinga le-electrode lohlobo ngalunye kanye nokucaciswa kufanele thobelana nezidingo kuThebula 7. Ngaphambi kokuhlolwa, i-electrode kufanele ibhakwe ngokuhambisana nezinga lokushisa lokumisa elethulwe ngumenzi.
