Ukudityaniswa kwemibhobho yokudibanisa, apho iinxalenye ezimbini okanye ngaphezulu zisebenzisa indibaniselwano yamalungu adityanisiweyo, okanye ibhekisa kumalungu amabini okanye ngaphezulu adityaniswe ngokudityaniswa kwe-welding, kubandakanywa i-welds, indawo yokudibanisa kunye nendawo echaphazelekayo yokushisa.

Indawo edibeneyo edibeneyo

Emva kokufaka isinyithi kunye nentsimbi yokuzalisa inyibilika ngokukhawuleza isantya seYouyi esakhiwe emva kokupholisa kunye nokuqina.I-Weld ukusuka kwisakhiwo sokuphonswa kweekristale zetsimbi ezinolwelo, iinkozo ezirhabaxa, ulwahlulo, umbutho awuxinene.Nangona kunjalo, ngenxa ye-weld pool encinci, ukupholisa ngokukhawuleza, ulawulo olungqongqo lwemichiza, i-carbon, isulfure, i-phosphorus iphantsi, kodwa kwakhona ngokulungelelanisa ukwakheka kweekhemikhali ze-alloying ye-weld, iqulethe inani elithile lezinto ezixutywayo, ngoko ke ukusebenza kwentsimbi weld hayi ingxaki enkulu, ukuhlangabezana neemfuno zokusebenza, ingakumbi amandla ukufikelela lula.

Indawo yeFusion

Indawo yokunyibilika kunye nenxalenye yotshintsho phakathi kwendawo enganyibilikiyo.Ukwakheka kweekhemikhali kwindawo edityanisiweyo engalinganiyo izicubu ezityebileyo zihlala zirhabaxa eziqinileyo okanye iithishu ezishushu kakhulu.Ukusebenza kwamalungu adityanisiweyo kuhlala kubi kakhulu.Ummandla we-Fusion kunye nobushushu obuchaphazelekayo kwindawo eshushu (okanye indawo yokucima) yeyona nto imbi kakhulu yeempawu zemishini yamalungu adityanisiweyo abuthathaka, ziya kuchaphazela kakhulu umgangatho wamalungu adityanisiweyo.

Indawo echaphazelekayo yobushushu

Ubushushu obuphezulu be-weld zone microstructure kunye neepropati ezibangelwa utshintsho kummandla.Indawo ephantsi kwekhabhoni yentsimbi echaphazeleke bubushushu inokwahlulwa ibe ziindawo ezishushu kakhulu, kwaye inxalenye yendawo yokutshintsha kwesigaba iqhelekile.

(1) eyona ndawo iphezulu yobushushu bobushushu bommandla ongaphezulu kwe-1100℃, iinkozo ezirhabaxa, kwanezicubu ezitshisa kakhulu, ezibizwa ngokuba ngummandla wobushushu obugqithiseleyo.I-Ductility kunye nokuqina kwehle kakhulu indawo eshushu kakhulu, indawo echaphazelekayo yobushushu yeyona ndawo imbi yeempawu zoomatshini.

(2) Ubushushu obuphezulu bokufudumeza ukusuka kwindawo yesiqhelo ye-Ac3 ukuya kwi-1100℃, i-air-cooled welding grains iba yincinci emva kombutho oqhelekileyo obizwa ngokuba yi-normalizing area.Iipropati ezingcono zoomatshini bommandla oqhelekileyo.

(3) inxalenye yowona mmandla uphezulu wokutshintsha ubushushu besigaba sotshintsho ukuya kummandla ukusuka kwi-Ac1 Ac3, inxenye kuphela yotshintsho lwesigaba sombutho, esibizwa ngokuba ngummandla wesigaba sotshintsho.Ukungasebenzi kakuhle kwale ndawo okuziinkozo nako kubi.Ngexesha lokufakela i-welding, indlela ye-welding ye-welding rhoqo.Ubushushu obuphezulu obudityanisiweyo yintsimbi yematriki efudunyeziweyo kunye nomzimba ofanayo wokuzalisa wesinyithi esinyibilikisiweyo ngelixa uqinisa ifom etyhidiweyo.Ngokuxhomekeke kwi-microstructure kunye neepropati zeendawo ezahlukeneyo ze-welded joints zinokwahlulwa zibe ngamacandelo amathathu.
