Ukuhlaziywa kwezizathu zokuqhekeka kokushisela okuthile kwesakhiwo kwenziwa kusuka ezicini ezine: i-macroscopic morphology yejoyinti lokushisela, i-microscopic morphology, ukuhlaziywa kwe-energy spectrum, kanye nokuhlaziywa kwe-metallographic ye-welding joint.umshini wokushisela indawo we-mid-frequency spotukushisela. Ukubhekwa nokuhlaziywa kubonisa ukuthi ukuqhekeka kwe-welding kubangelwa amandla angaphandle, ngokuyinhloko ngenxa yokuba khona kokukhubazeka okubanzi kwe-welding, nezinqubo ezingalungile ze-welding kanye nokuhlanzwa okwanele kwezindawo zokushisela kube yizici eziyinhloko ezibangela lezi zinkinga. Ngezansi kunezinkinga ezimbalwa eziholela ekuqhekekeni kwamalunga:
Ukuqhekeka kwe-Crystalline:
Ngesikhathi sokuqiniswa kanye nokucwebezela kwechibi lokushisela, imifantu yakheka eduze kwemingcele yokusanhlamvu yensimbi yokushisela ngenxa yokuhlukaniswa kwekristalu nokucindezeleka kokuncipha kanye nokucindezeleka. Lezi ziqhekeko zenzeka kuphela ngaphakathi kwe-weld.
Imifantu ye-Liquation:
Ngesikhathi sokushisela, ngaphansi kwethonya lamazinga okushisa aphezulu kumjikelezo wokushisa we-welding, insimbi ye-intergranular eduze ne-weld seam kuma-interlayers we-welds multi-layer ingase incibilike kabusha ngenxa yokushisa. Ngaphansi kokucindezeleka okuthile kokuncipha, imifantu ikhula eduze kwemingcele yezinhlamvu ze-austenite, into ngezinye izikhathi ebizwa ngokuthi ukuklebhula okushisayo.
Izinga lokushisa eliphansi lokuqhekeka kwe-ductility:
Ngemva kokuphothulwa kwe-crystallization yesigaba se-liquid, njengoba insimbi ehlanganisiwe eshiselwe iqala ukupholisa kusukela ekushiseni kwe-ductile yokutakula, ezintweni ezithile, lapho ipholiswe ebangeni elithile lokushisa, i-ductility iyancipha ngenxa yokusebenzisana kwesilinganiso sobunzima kanye nezici ze-metallurgical, okuholela. ukuqhekeka eduze kwemingcele yokusanhlamvu yensimbi ehlanganisiwe eshiselwe. Lolu hlobo lokuqhekeka ngokuvamile lwenzeka endaweni ethinteke ukushisa ekude nomugqa wokuhlanganisa kunemifantu yoketshezi.
Phinda ushise imifantu:
Ngemuva kokushisela, ngesikhathi sokwelashwa kokushisa kokunciphisa ukucindezeleka noma ngaphandle kokwelashwa kokushisa, imifantu ikhula eduze kwemingcele yezinhlamvu ze-austenite zensimbi ye-weld ezingeni lokushisa elithile ngaphansi kwezimo ezithile. Ukuqhekeka kokushisa kabusha kuyinkinga ebalulekile ekushiseleni izinsimbi ezine-alloy enamandla aphezulu, ikakhulukazi kumapuleti awugqinsi wezinsimbi ezinekhabhoni ephezulu yealloy kanye nezinsimbi ezikwazi ukumelana nokushisa eziqukethe inani elikhulu lezinto ezenza i-carbide (njenge-Cr. , Mo, V). Ukubhekana nalezi zinkinga kudla isikhathi futhi kunomthelela omkhulu ekukhiqizeni.
I-Suzhou Agera Automation Equipment Co., Ltd. igxile ekuthuthukisweni kokuhlanganisa okuzenzakalelayo, ukushisela, okokuhlola, nemigqa yokukhiqiza, ngokuyinhloko isebenzela izimboni ezifana nempahla yasendlini, ukukhiqiza izimoto, insimbi yeshidi, kanye nogesi we-3C. Sihlinzeka ngemishini yokushisela eyenziwe ngokwezifiso, imishini yokushisela ezenzakalelayo, kanye nemigqa yokukhiqiza i-welding ngokusho kwezidingo zamakhasimende, ukuhlinzeka ngezixazululo ezifanele zokuzenzakalela ukusiza izinkampani ekuguqukeni ngokushesha ezindleleni zokukhiqiza zendabuko ziye ezindleleni zokukhiqiza eziphezulu. Uma unentshisekelo kumishini yethu ye-automation kanye nemigqa yokukhiqiza, sicela usithinte: leo@agerawelder.com
