Uhlalutyo lwezizathu zokuqhekeka kwi-welds yesakhiwo esithile lwenziwa kwiinkalo ezine: i-macroscopic morphology ye-welding joint, i-microscopic morphology, uhlalutyo lwe-spectrum yamandla, kunye nohlalutyo lwe-metallographic ye-welding joint.umatshini wokuwelda indawo ephakathi rhoqoukuwelda. Ukuqwalaselwa kunye nokuhlalutya kubonisa ukuba ii-welding cracks zibangelwa amandla angaphandle, ngokuyinhloko ngenxa yobukho be-welding defects ebanzi, kunye neenkqubo ze-welding ezingafanelekanga kunye nokucocwa okungonelanga kweendawo ze-welding kuba zizinto eziphambili ezibangela ezi ziphene. Ngezantsi kukho iingxaki ezininzi ezikhokelela ekuqhekekeni kwamalungu:
Iintanda zeCrystalline:
Ngethuba lokuqiniswa kunye ne-crystallization ye-welding pool, ii-cracks zenzeke ecaleni kwemida yeenkozo ze-weld metal ngenxa yokwahlula i-crystallization kunye noxinzelelo lwe-shrinkage kunye noxinzelelo. Ezi ntanda zenzeke kuphela kwi-weld.
Iintanda zotywala:
Ngexesha le-welding, phantsi kwefuthe lobushushu obuphezulu kwi-welding heat cycle, isinyithi se-intergranular kufuphi ne-weld seam kwi-interlayers ye-welds ye-multi-layer inokuphinda inyibilike ngenxa yokufudumala. Ngaphantsi koxinzelelo oluthile lwe-shrinkage, iintanda zikhula ecaleni kwemida ye-austenite, into eyenzeka ngamanye amaxesha ebizwa ngokuba kukukrazula okushushu.
Iintanda ezinobushushu obuphezulu obuphantsi:
Emva kokugqitywa kwecrystallization yesigaba solwelo, njengoko isinyithi esidityanisiweyo siqala ukupholisa kwiqondo lobushushu lokubuyisela i-ductile, kwizinto ezithile, xa lupholile kuluhlu oluthile lobushushu, i-ductility iyancipha ngenxa yentsebenziswano yezinga loxinzelelo kunye nezinto zetsimbi, ezikhokelela ekuphuhliseni. ukuqhekeka ecaleni kwemida yeenkozo zentsimbi edityanisiweyo. Olu hlobo lokuqhekeka ngokuqhelekileyo lwenzeka kwindawo echaphazelekayo kubushushu kude nomgca wokudibanisa kunokuqhekeka kotywala.
Phinda ufudumeze iintanda:
Emva kwe-welding, ngexesha loxinzelelo loxinzelelo lonyango lobushushu okanye ngaphandle konyango lobushushu, iintanda zikhula ecaleni kwemida ye-austenite yengqolowa yentsimbi ye-weld kwiqondo lokushisa elithile phantsi kweemeko ezithile. Ukufudumeza kwakhona iintanda ngumba obalulekileyo ekudityanisweni kweentsimbi ezisezantsi-zoluqilima, ngakumbi kwiintsimbi ezishinyeneyo zeplate eshinyeneyo yeentsimbi ezinekhabhoni ephezulu kunye neentsimbi ezikwaziyo ukumelana nobushushu eziqulethe isixa esikhulu sezinto ezenza i-carbide (ezifana neCr. , Mo, V). Ukujongana nezi ziphene kuthatha ixesha kwaye kunempembelelo enkulu kwimveliso.
