Ukuqinisekisa umgangatho we-welding yeyona nto iphambili koomatshini bokuwelda i-butt ukuqinisekisa ukuthembeka kunye nokuthembeka kwamalungu adityanisiweyo. Iindlela zokubona ezifanelekileyo zibalulekile ukuchonga iziphene ezinokubakho kunye nokuphambuka okunokuthi kubeke esichengeni ukusebenza kwe-weld. Eli nqaku liphonononga iindlela ezisetyenziselwa ukufumanisa umgangatho we-welding kumatshini we-welding we-butt, egxininisa ukubaluleka kwabo ekugcineni imigangatho ephezulu yokuthembeka kwe-weld.
- Ukuhlolwa okubonakalayo: Ukuhlolwa okubonakalayo yeyona ndlela ichanekileyo kunye neyokuqala yokubona umgangatho we-welding. Abachwephesha abanobuchule kunye nabahloli bahlola ngononophelo inkangeleko ye-weld bead, bekhangela iziphene ezibonakalayo ezifana nokuqhekeka, i-porosity, ukudibanisa okungaphelelanga, okanye ukungahambi kakuhle kwiprofayili ye-bead.
- Uvavanyo lwe-Penetrant (PT): Uvavanyo lwe-Penetrant luvavanyo olungonakalisi (NDT) olubandakanya ukusebenzisa i-liquid penetrant kwi-weld surface. Emva kwexesha elithile lokuhlala, ukungena okugqithisileyo kuyasuswa, kwaye umphuhlisi usetyenziselwa ukukhupha nayiphi na indawo ebambeke kwiiphene zomhlaba. Le ndlela inokuchonga iintanda ezintle kunye neziphene ezinokuthi zingabonakali ngeso lenyama.
- Uvavanyo lweMagnetic Particle (MT): Uvavanyo lwemagnethi lobunye ubuchule be-NDT obusetyenziselwa ukufumanisa iziphene ezikumphezulu kunye nezikufutshane nomphezulu. Umphezulu we-weld unemagnethi, kwaye amasuntswana omagnetic asetyenziswa. Xa iziphene zikhona, iincinci zemagnethi ziqokelela kwaye zenze izibonakaliso ezibonakalayo, ezivumela abahloli ukuba bahlole umgangatho we-weld.
- Uvavanyo lwe-Ultrasonic (UT): Uvavanyo lwe-Ultrasonic yindlela ye-NDT ye-volumetric esebenzisa amaza omsindo we-high-frequency ukuhlola i-welds. Amaza e-Ultrasonic adluliselwa kwi-weld, kwaye naziphi na iziphene zangaphakathi okanye ukungaqhubeki kubonisa amaza abuyele kumamkeli. Le ndlela igqwesileyo ekuboneni iziphene zangaphakathi kunye nokuvavanya isandi se-weld.
- Uvavanyo lweRadiographic (RT): Uvavanyo lweRadiographic lubandakanya ukugqithiswa kwe-X-reyi okanye imitha ye-gamma kwi-weld kunye nokurekhoda ukusasazeka kwemitha kwifilimu okanye kwizixhobo zedijithali. Le ndlela inokubona iziphene zangaphakathi ezifana ne-voids, inclusions, kunye nokungabikho kokudibanisa, ukubonelela ngolwazi olucacileyo malunga nesakhiwo sangaphakathi se-weld.
- Uvavanyo lwe-tensile: Uvavanyo lwe-tensile lubandakanya ukubeka isampulu ye-weld kumandla okuqina okulawulwayo de yophuka. Olu vavanyo lunceda ekuvavanyeni iipropathi zoomatshini beweld, njengamandla okuqina kunye nobude, kwaye ibonelela ngemibono kumandla kunye nokusebenza kweweld.
- Uvavanyo lwe-Bend: Uvavanyo lwe-Bend lusetyenziselwa ukuvavanya i-ductility kunye nesandi se-welds. Icandelo le-weld ligotywe kwiradiyasi ethile ukubona ukuba kukho iintanda okanye iziphene ezivela kumphezulu ongaphandle. Olu vavanyo luluncedo kakhulu ekuboneni iziphene kwi-welds ezinokuthi zingabonakali kuhlolo olubonakalayo.
Ukuqukumbela, ukufumanisa umgangatho we-welding koomatshini bokuwelda i-butt kubalulekile ekuqinisekiseni ukuba amalungu adityanisiweyo athembekileyo kunye nokusebenza okuphezulu. Uhlolo olubonakalayo lubonelela ngovavanyo lokuqala, ngelixa iindlela ezahlukeneyo zovavanyo ezingonakalisi njenge-PT, MT, UT, kunye ne-RT zibonelela ngolwazi olunzulu ngakumbi kwingqibelelo ye-weld. Uvavanyo lwe-tensile kunye novavanyo lokugoba lubonelela ngolwazi oluxabisekileyo malunga neempawu zomatshini we-weld kunye ne-ductility. Ngokusebenzisa obu buchule bokubona, abaqhubi be-welding kunye nabahloli banokubamba imigangatho yomgangatho ongqongqo, bachonge iziphene ezinokubakho, kwaye benze izigqibo ezinolwazi ukulungisa nayiphi na imiba, ukuqinisekisa ukusebenza okuhambelanayo kunye nokuxhomekeka kwe-welding kwizicelo ezahlukeneyo.
