1.Kusankha kwazinthu ndi kupangira kuwotcherera kumagwirizana ndi ASME Boiler ndi Pressure Vessel Code ndi ANSI Pressure Pipeline Code.

2. Kupangidwa kwa mankhwala azitsulo zazitsulo zowotcherera ndi zipangizo zowonongeka ziyenera kutsata zomwe zili muyeso.Zomwe zili m'munsizi ziyenera kukhala molingana ndi maukadaulo a ASTM pamitu yoyenera B165, B164, B127.zinthu zodzaza ziyenera kukhala molingana ndi zinthu zodzaza ASME A-42 za ER-NiCu-7 kapena ER-ENICu-4.

3. Mtsinje wa weld ndi malo ozungulira a banga (mafuta ester, filimu ya mafuta, dzimbiri, etc.) ayenera kutsukidwa ndi njira yoyeretsera.

4. Pamene kutentha kwa zinthu m'munsi ndi zosakwana 0 ℃, chofunika preheat kuti 15.6-21 ℃, ndi weld bevel wa zinthu ndi kutentha kwa 16-21 ℃ mkati 75mm.

5. The weld bevel prefabricated makamaka zimadalira malo kuwotcherera ndi makulidwe a zinthu, Monel aloyi amafuna bevel ngodya wa weld kuposa zipangizo zina, m'mphepete osamveka kuposa zipangizo zina kukhala yaing'ono, pakuti monel aloyi mbale makulidwe a 3.2 -19mm, ngodya ya bevel ndi 40 ° ngodya yokhala ndi m'mphepete mwa 1.6mm, kusiyana kwa mizu ya 2.4mm, kuchepera 3.2mm weld kumbali zonse ziwiri kuti ikhale yodulidwa mozungulira kapena yodulidwa pang'ono, osati bevel.Mbali zowotcherera zimayamba kupangidwa ndi njira zamakina, kapena njira zina zoyenera, monga kupanga arc gas planing kapena plasma cutting, arc cutting.Mosasamala njira, mbali ya weld iyenera kukhala yofanana, yosalala komanso yopanda burr, bevel sikhala ndi slag, dzimbiri ndi zonyansa zovulaza, ngati pali ming'alu ya slag ndi zolakwika zina ziyenera kupukutidwa ndikufufuzidwa mosamala musanawotchererane. .

6. Zofunikira za makulidwe a mbale zakuthupi, makulidwe azinthu zovomerezeka (4-23mm) mpaka 19mm zololeka zowotcherera, makulidwe ena amathanso kuwotcherera koma amafunikira chojambula chatsatanetsatane.

7. Kuwotcherera pamaso pa ndodo yowotcherera kuti ziume mankhwala, kuyanika kutentha kutentha pa 230 - 261 C.

8. Kuwotcherera zinthu: pamwamba pa welded mbali sangathe welded chifukwa mvula ndi chinyezi, mvula masiku, mphepo masiku sangakhale lotseguka kuwotcherera, pokhapokha kukhazikitsa okhetsedwa zoteteza.

9. Palibe chithandizo cha kutentha chofunika pambuyo kuwotcherera.

10. Ambiri mwa luso kuwotcherera ndi zitsulo Arc kuwotcherera (SMAW), angagwiritsidwenso ntchito mpweya kutetezedwa tungsten Arc kuwotcherera (GTAW), kuwotcherera basi ndiosavomerezeka.Ngati kuwotcherera basi ntchito, ndiye argon Arc kuwotcherera, ntchito kuwotcherera ndodo si kugwedezeka kuwotcherera ndondomeko, kuti kuwotcherera zitsulo fluidity ntchito, akhoza pang'ono kugwedezeka kuthandiza otaya zitsulo weld, koma pazipita swing m'lifupi amachita. osapitirira kawiri m'mimba mwake wa ndodo yowotcherera, pogwiritsa ntchito njira ya SMAW yowotcherera yosavutamagawo ndi: Mphamvu: kulumikiza molunjika, mobwerera kumbuyo, kugwiritsira ntchito kolakwikaVoltge: 18-20VCurrent: 50 - 60AElectrode: kawirikawiri φ2.4mm ENiCu-4 (Monel 190) electrode

11. Kuwotcherera mawanga kuyenera kuphatikizidwa muzu wa njira yowotcherera.

12. Pambuyo popanga weld, palibe malire omwe amaloledwa kukhalapo.

13. Kuwotcherera matako kuyenera kulimbikitsidwa, kutalika kwa kulimbikitsa kuyenera kukhala kosachepera 1.6mm ndipo osapitirira 3.2mm, kuwonetserako kuyenera kukhala kosapitirira 3.2mm, ndipo osapitirira 3.2mm kwa bevel ya chitoliro.

14. Pambuyo kuwotcherera aliyense wosanjikiza wa weld, ayenera kuwotcherera flux ndi adhesion ndi zosapanga dzimbiri waya burashi kuchotsa woyera, pamaso kuwotcherera lotsatira wosanjikiza.

15. Chilema kukonza: Pamene ubwino wa vuto kuwotcherera, ntchito akupera ndi kudula kapena arc mpweya adzakhala anakumba kunja zolakwika mpaka mtundu chitsulo choyambirira, ndiyeno kachiwiri weld malinga ndi ndondomeko kuwotcherera choyambirira ndi makonzedwe luso, musatero. kulola njira yokhotakhota kuti itseke chitsulo chowotcherera kapena kudzaza pabowo ndi zinthu zakunja.

16. Mpweya wazitsulo zokutira zowotcherera Monel aloyi ntchito p2.4mm kuwotcherera ndodo, chifukwa welded Monel aloyi wosanjikiza ayenera kukhala osachepera 5mm wandiweyani, pofuna kupewa ming'alu, ayenera kugawidwa mu zigawo ziwiri za kuwotcherera.Gawo loyamba ndi gawo losinthira la aloyi ya Monel yosakanikirana ndi chitsulo cha carbon.Wosanjikiza wachiwiri pamwamba koyera Monel aloyi wosanjikiza, pambuyo processing kuonetsetsa kuti pali koyera Monel aloyi ogwira makulidwe wosanjikiza 3.2mm, aliyense welded wosanjikiza kuti utakhazikika ndi kutentha firiji, ndi zosapanga dzimbiri waya burashi kuchotsa kuwotcherera flux pamaso kuwotcherera. pa wosanjikiza.

17. Makulidwe aakulu kuposa 6.35 mm a Monel aloyi mbale, matako kuwotcherera kugawidwa mu zigawo zinayi kapena kuposa kuwotcherera.Yoyamba zigawo zitatu zilipo zabwino kuwotcherera ndodo (φ2.4mm) kuwotcherera, otsiriza zigawo zingapo zilipo coarse kuwotcherera ndodo (φ3.2mm) kuwotcherera.

18. Monel aloyi kuwotcherera pakati pa AWS ENiCu-4 kuwotcherera ndodo ER NiCu-7 waya, carbon zitsulo ndi Monel aloyi kuwotcherera ndi EN NiCu-1 kapena EN iCu-2 kuwotcherera ndodo zina ndi chimodzimodzi monga mawu pamwamba.

kuwongolera khalidwe

Kuonetsetsa mtundu wa kuwotcherera, njira zoyesera zosawononga zimatengera kuwongolera mtundu, monga ma radiation, maginito tinthu tating'onoting'ono, akupanga, kulowa ndi njira zina zowunikira.Ma welds onse ayeneranso kuyang'aniridwa kuti awonetsere zolakwika za maonekedwe, monga ming'alu ya pamwamba, kuluma, kuyanjanitsa ndi kulowetsedwa kwa weld, ndi zina zotero.Zowotcherera muzu zonse ziyenera kuyang'aniridwa kuti ziwonekere, ndipo ngati pali zolakwika, ziyenera kukonzedwanso zotsalazo zisanawunikidwe.
