Muchokwadi, iyo simbi pombi munda ikozvino haiparadzaniswe kubva kune mamwe akawanda maindasitiri, akadai sekugadzira mota nekugadzira michina. Mota, muchina nekugadzira michina nemimwe michina nemidziyo zvine zvakakwirira zvinodiwa pakurongeka uye kutsetseka kwesimbi isina tsvina inopenya machubhu. Stainless simbi inopenya chubhu vashandisi havangove nepamusoro zvakanyanya zvinodiwa zvekunyatso uye kutsetseka. Nekuda kweiyo yepamusoro chaiyo yesimbi isina tsvina inopenya chubhu, iyo dimensional kushivirira inogona kuchengetedzwa pa 2-8 waya. Naizvozvo, mazhinji emakanika ekugadzirisa uye kugadzira vatengi vari kuitira kuchengetedza vashandi, zvinhu uye nguva. Nekupfeka uye kubvaruka,mapaipi asina musonokana kuti makambasi ari kuchinja zvishoma nezvishoma kuva simbi isina tsvina inopenya pombi. Zvadaro ngatitarisei matanho ekugadzirisa welding yesimbi isina tsvina inopenya machubhu:
Iyo welding process yestainless simbi inopenya machubhu: yemagetsi welding preheating, uye kupisa kurapwa maitiro mushure mewelding.
1. Kupisa:
Pamberi pearc welding yesimbi isina tsvina inopenya machubhu, simudza tembiricha yesimbi isina tsvina inopenya machubhu uye zvishoma nezvishoma weld mushure mekudzora tembiricha kwemaminitsi makumi matatu.
Iyo yekudziya uye chaiyo bhiza kupisa kurapwa kwearc arc welding inoshandirwa nekabati yekudzora tembiricha ine tembiricha kutonga. Shandisa far-infrared tracking heat treatment yemagetsi choto chendi. Hungwaru uye otomatiki machati uye kurekodha chati, iyo yekupisa yekupisa coefficient inoyera tembiricha. Kana tembiricha yasimudzwa, chinhambwe chiri pakati pekupisa kuchinjisa coefficient kuyerwa mapoinzi uye welding mupendero ndeye 15mm-20mm.
2. Welding process:
1. Kuti udzivise welding deformation ye Stainless simbi inopenya machubhu, yega yega yembiru majoini ano symmetrically welded nevanhu vaviri, ine welding nhungamiro kubva mukati kusvika mativi ese. Mashandiro ekuita welding yemukati yekuwedzera inlet (iyo welding iri padhuze nedanda kana yemukati yekuwedzera yakavhurwa) ndeye kutanga kubva padanho rekutanga reiyo chaiyo inopenya chubhu uye yechitatu layer yechaiyo inopenya chubhu kuita diki saizi modhi. nepazvinogona napo, nekuti arc welding yayo inokanganisa zvakanyanya chikonzero chewelding deformation. . Mushure mekunge arc arc welding yasvika padanho rechitatu, kudzosera kumashure kunofanirwa kuitwa. Mushure mekushandisa kabhoni arc gouging, midziyo yewelding inofanirwa kukwenenzverwa zvakanyanya sezvinobvira, uye iyo welding yepamusoro inofanira kunge yakakwira-frequency kudzimwa kuratidza kupenya kwesimbi uye kudzivirira kuputika kunokonzerwa necarburization pamusoro. Gomba rekunze rakasungwa kamwe chete uye dzimwe shinda dzekunze dzinosungwa kamwe chete.
2. Kana arc arc welding = kaviri-layer precision inopenya chubhu, iyo welding inotungamira inofanira kunge yakatarisana neyakatsetseka inopenya chubhu, zvichingodaro. The welding kureba pakati imwe neimwe layer ndeye 15-20mm.
3. The welding current uye welding kunyatsoshanda kwemakina akawanda anorema kunofanirwa kuchengetedzwa, pamwe nenhamba yekuputirana mazaya echando ekuunganidza.
4. Muarc welding, edza kupinza zvishoma nezvishoma kubva paarc yekutanga ndiro uye pedzisa kubatira paarc yekutanga ndiro. Mushure mekucheka kwearc, bvisa uye politisha.
