Yintoni endimele ndiyenze ukuba ndidibana neziphene ezingaxutywanga kunye nezingangeni emva kwe-valve welding?

1. Iimpawu zesiphene
Ukungaxutywanga kubhekiselele kwinto yokuba intsimbi ye-weld ayinyibiliki ngokupheleleyo kwaye idityaniswe nesiseko sesinyithi okanye phakathi kweemaleko zentsimbi ye-weld.
Ukungaphumeleli ukungena kubhekisela kwinto yokuba ingcambu ye-welded joint ayingeni ngokupheleleyo.
Bobabini ukungabikho kwe-fusion kunye nokungangeni kuya kunciphisa indawo esebenzayo ye-cross-sectional weld, ukunciphisa amandla kunye nokuqina.
2. Oonobangela
Isizathu sokungaxutywanga: i-welding current incinci kakhulu okanye isantya se-welding sihamba ngokukhawuleza, okubangelwa ukushisa okunganeleyo, kwaye isiseko sesinyithi kunye nentsimbi yokuzalisa ayinakuncibilika ngokupheleleyo. I-angle ye-groove incinci kakhulu, i-gap incinci kakhulu okanye i-edge e-blunt inkulu kakhulu, ukwenzela ukuba i-arc ayikwazi ukungena nzulu kwingcambu ye-groove ngexesha le-welding, okubangelwa isiseko sesinyithi kunye nentsimbi ye-weld engaxutywanga. Kukho ukungcola okufana ne-oil stain kunye ne-rust ebusweni be-weldment, echaphazela ukunyibilika kunye nokudibanisa kwesinyithi. Ukusebenza okungafanelekanga, njenge-electrode angle engalunganga, indlela engafanelekanga yokuthutha ibha, njl., yenza i-arc iphambuke kumda we-groove okanye ihluleke ukugubungela ngokwaneleyo i-groove.
Izizathu zokungangeni: Ngokufana nezinye izizathu zokungaxutywanga, njenge-welding encinci yangoku, isantya se-welding esikhawulezayo, ubungakanani begroove engafanelekanga, njl. ekunyibilikeni kakubi kwengcambu yesinyithi. I-gap yendibano ye-weldment ayilingani, kwaye kulula ukuba akukho ukungena kwe-weld kwinxalenye ene-gap enkulu.
3. Ukulungiswa
Unyango olungadityaniswanga: Kwimigangatho engadityaniswanga, ivili lokusila lingasetyenziselwa ukupolisha iindawo ezingadityaniswanga kwaye emva koko u-weld kwakhona. Xa uphinda u-welding, iiparitha zenkqubo ye-welding kufuneka zilungiswe ukuze kuqinisekiswe igalelo elaneleyo lokushisa ukunyibilikisa ngokupheleleyo isiseko sesinyithi kunye nentsimbi yokuzalisa. Ukungadibanisi kwangaphakathi, kuyafuneka ngokubanzi ukuba kusetyenziswe iindlela zovavanyo ezingonakalisiyo ukumisela indawo kunye nobungakanani bokungadibanisi, kwaye emva koko usebenzise i-carbon arc gouging okanye iindlela zomatshini ukususa iindawo ezingadibanisiyo, kwaye emva koko wenze ukulungiswa. ukuwelda. Xa ulungisa i-welding, qaphela ukucoca i-groove, lawula i-angle ye-welding kunye nendlela yokuthutha ibha.
Ukunyangwa okungenakuthintelwa: Ukuba ubunzulu bokungena okungaxutywanga bunzulu, inxalenye engabonakaliyo ingasuswa ngokugaya ngevili lokugaya, kwaye emva koko ulungise i-welding. Ngobunzulu obukhulu, ngokuqhelekileyo kuyimfuneko ukusebenzisa i-carbon arc gouging okanye i-machining ukususa zonke iindawo zokungena kwe-weld de isinyithi esilungileyo sibonakaliswe, kwaye silungise i-welding. Xa ulungisa i-welding, i-welding current, i-voltage kunye ne-welding speed kufuneka ilawulwe ngokungqongqo ukuqinisekisa ukuba ingcambu ingangena ngokupheleleyo.
4. Lungisa izinto ze-welding
Ngokuqhelekileyo, izinto ze-welding ezifanayo okanye ezifana nesiseko se-valve kufuneka zikhethwe. Ngokomzekelo, kwii-valve ze-carbon steel eziqhelekileyo, i-E4303 (J422) iintonga ze-welding zingakhethwa; Kwiivalvu zensimbi ezingenasici, i-welding yentsimbi ehambelanayo ingakhethwa ngokwezinto ezithile, ezifana ne-A102 ye-welding rods ye-304 stainless steel.iivalve, A022 iintonga welding for 316L steel stainlessiivalve, njl.
