Ukuhlolwa okumnandi
Amashubhu wensimbi anobubanzi obungaphandle obukhulu kune-22 mm futhi aze afike ku-400 mm, kanye nodonga olukhulu olungaphezu kwe-10 mm kufanele luhlolwe isivivinyo se-flattening. Ngemuva kokuthi amasampula athambile
Ukuhlolwa kokugoba
Amashubhu wensimbi anobubanzi obungaphandle abukhulu kune-22 mm kufanele ahlolwe. I-engela yokugoba ngu-90o. I-Beading Radius izikhathi ezi-6 ububanzi obungaphandle kweshubhu lensimbi.I-BEAFT eboshwe isampula, akukho micures noma imifantu evunyelwe ukuvela kwisampula.
Ukuhlolwa kweMacroscopic
Amashubhu wensimbi eyenziwe ngokuqondile ngamabhilidi aqhubekayo noma ama-ingots ensimbi, iqembu lokuhlinzeka kufanele liqinisekise ukuthi azikho amabala amhlophe, ukungcola, ama-bubble air acid, izimbotshana ze-acid acid acid acid ezikhethiwe ze-macroscopic ze-billet noma ishubhu lensimbi.
Ukuhlolwa okungeyona eyonakalisayo
Ngokwesicelo seqembu elifunayo, elixoxiswana ngalo phakathi kokuhlinzeka ngamaqembu afunekayo futhi liboniswe esivumelwaneni, ukutholwa kwe-FACEKI kwe-Ultrasonic kungahle kwenziwe ngamashubhu wensimbi. Isici se-Longitudinal Manual sethebhu yesampula yesethenjwa kufanele sihlangabezane nezidingo zokwamukelwa kwebanga lokuhlola ngemuva kokuhlolwa kwe-CB / T 5777-1996.
