Lisosa tsa Mapheo a Lichelete tsa Bohareng ba Hangata Spot Welds

Tlhahlobo ea mabaka a mapetsong a litšepe tse itseng tsa meralo e etsoa ho tsoa likarolong tse 'ne: morphology ea macroscopic ea lenonyeletso la welding, morphology ea microscopic, tlhahlobo ea matla a matla, le tlhahlobo ea metallographic eamochini o tjheseletsang letheba la mahareng a maqhubucheseletso. Maikutlo le tlhahlobo li bontša hore mapetsong a tjheseletsa a bakoa ke matla a ka ntle, haholo-holo ka lebaka la ho ba teng ha mefokolo e mengata ea ho tjheseletsa, ka mekhoa e sa lokelang ea ho tjheseletsa le ho hloekisa ka ho lekaneng ha libaka tsa welding e le tsona lintlha tse ka sehloohong tse tlatsetsang mefokolong ena. Ka tlase ke mathata a 'maloa a lebisang ho petsoha ha manonyeletso:

Crystalline cracks:
Nakong ea ho tiisa le kristale ea letamo la welding, mapetsong a theha moeling oa lijo-thollo tsa tšepe ea weld ka lebaka la karohano ea crystallization le khatello ea maikutlo le khatello ea maikutlo. Mapetsong ana a hlaha feela ka har'a cheseletso.

Liquation cracks:
Nakong ea tjheseletsa, tlas'a tšusumetso ea mocheso tlhōrō ka tjheseletsa mocheso potoloho, intergranular tšepe haufi le tjheseletsa seam ka interlayers ea multi-lera tjheseletsa ka 'na boela qhibiliha ka lebaka la ho futhumatsa. Tlas'a khatello e itseng ea shrinkage, mapetsong a hlaha haufi le meeli ea lijo-thollo tsa austenite, ketsahalo eo ka linako tse ling e bitsoang ho rusolla ho chesang.
Mapetsong a mocheso o phahameng o tlase oa ductility:
Ka mor'a ho phethoa ha mokelikeli mohato crystallization, ha tšepe welded kopanetsweng qala ho pholile ho tloha lintho tse bonahalang ductile hlaphoheloa mocheso, bakeng sa thepa e itseng, ha cooled ho mocheso itseng mefuta e fapaneng ya mocheso, ductility fokotseha ka lebaka la ho sebelisana le sekhahla khatello le lintlha metallurgical, isang. ho petsoha ka mathoko a mabele a tshepe e kopanetsweng. Mofuta ona oa ho petsoha ka kakaretso o etsahala sebakeng se anngoeng ke mocheso hole le mola oa fusion ho feta mapetsong a metsi.
Reheat cracks:
Ka mor'a ho tjheseletsa, nakong ea phekolo ea mocheso oa khatello ea kelello kapa ntle le phekolo leha e le efe ea mocheso, mapetsong a hlaha haufi le meeli ea lijo-thollo ea austenite ea tšepe ea weld ka mocheso o itseng tlas'a maemo a itseng.
