1. Welding analysis: 1. Cr18Ni9Ti simbi isina tsvinaФ159mm×12mm pombi hombe yakachinjika yakamisikidzwa butt majoini anonyanya kushandiswa mumidziyo yemagetsi enyukireya uye mimwe michina yemakemikari inoda kupisa uye asidi kuramba.Iyo welding yakaoma uye inoda yakakwirira welding majoini.Iyo yepamusoro inodiwa kuti iumbwe, ine mwero protrusions uye pasina recesses.Kuongororwa kwePT uye RT kunodiwa mushure mekutambisa.Kare, TIG welding kana manual arc welding yaishandiswa.Iyo yekutanga ine yakaderera kushanda uye yakakwira mutengo, nepo yekupedzisira yakaoma kuvimbisa uye ine yakaderera kushanda.Kuti ive nechokwadi uye uwedzere chiyero, iyo yepasi pasi inosungirirwa neTIG yemukati uye yekunze waya yekuzadza nzira, uye iyo MAG welding inoshandiswa kuzadza nekuvhara iyo yepamusoro denga kuitira kuti kunyatsoshanda kuvimbiswa.2. Thermal kuwedzera mwero uye magetsi conductivity of 1Cr18Ni9Ti Stainless simbi zvakasiyana chaizvo neaya kabhoni simbi uye yakaderera-alloy simbi, uye dziva yakanyungudutswa ine urombo fluidity uye kushata kuumbwa, kunyanya kana welding panzvimbo dzose.Kare, MAG (Ar+1%～2% O2) welding simbi isina simbi yaiwanzo shandiswa paflat welding uye flat fillet welding.Mune MAG welding process, kureba kwewaya yewelding isingasviki 10mm, iyo swing amplitude, frequency, kukurumidza, uye mupendero wekugara nguva yepfuti yekubatira yakanyatso kurongeka, uye chiito chinorongwa.Gadzirisa kona yepfuti yewelding chero nguva, kuitira kuti welding seam surface edge isanganiswe zvakanaka uye zvakanakisa kuumbwa kuti ive nechokwadi chekuzadza Uye yekuvhara layer.

2. Welding nzira: Nyaya yacho 1Cr18Ni9Ti, ukuru hwepombi ndiyoФ159mm×12mm, hwaro hunogadzirwa nemanual argon arc welding, yakasanganiswa gasi (CO2 + Ar) yakadzivirirwa welding uye yekuvhara welding, yakatwasuka uye yakachinjika yakagadziriswa yese-nzvimbo welding.

3. Kugadzirira kusati kwaputira: 1. Geza mafuta netsvina, uye geda groove pamusoro uye 10mm yakapoteredza kuti uwane metallic luster.2. Ongorora kana masekete emvura, magetsi, uye gasi haana kuvharwa, uye midziyo nezvimwe zvinhu zviri muchimiro chakanaka.3. Unganidza maererano nehukuru.Tack welding inogadziriswa nembabvu (2 mapoinzi, 7 mapoinzi, uye 11 mapoinzi anogadziriswa nembabvu), kana mune groove positioning welding, asi teerera kune tack welding.
