Ukuze uthole imiphumela engcono yokuqapha, kubalulekile ukukhetha kahle imingcele yokuqapha ukukhishwa kwe-acousticumshini wokushisela indawo we-mid-frequency spotukuqapha imishini. Lawa mapharamitha ahlanganisa: ukuzuza okuyinhloko kwe-amplifier, izinga le-welding threshold, ileveli ye-spatter threshold, ileveli ye-crack threshold, isikhathi sokulibaziseka kokuqhekeka, isikhathi sokuqhekeka, iwindi lemvamisa, iwindi lesikhathi, njll. Le mingcele kufanele ikhethwe ngokusekelwe kuzici zokukhishwa kwe-acoustic zokushisela, i-spatter. , kanye nemifantu.
Ngokucacile, amapharamitha amane okuqala akhethwa ngokuyinhloko ngokusekelwe endaweni yesignali yokukhipha i-acoustic ku-eksisi yesikhathi kanye nobukhulu be-amplitude yesiginali. Ukuzuza kwe-amplifier okuyinhloko kufanele kuhlanganiswe ngokufanele nevelu ye-threshold. Akufanele kucatshangwe ukuthi ukuzuza okuphezulu kungcono, futhi amanani aphansi angcono.
Iwindi lefrikhwensi lisho imvamisa emaphakathi ye-transducer nesihlungi kanye nezici ezihlukene zokuphendula amafrikhwensi. Izindawo ezihlukene zinezimpawu ezihlukene zokugxambukela, ngakho-ke iwindi lemvamisa elikhethiwe kufanele likwazi ukwamukela amasiginali acebe kakhulu wokukhishwa kwe-acoustic ngenkathi ligwema ukuphazamiseka.
Iwindi lesikhathi lisethelwe ukususa amasiginali okuphazamisayo kusiginali yokukhipha i-acoustic okokufaka. Kubalulekile ukulungisa isango lokulawula i-logic ukuze uvule futhi uvale isango kanye newindi lemvamisa yesikhathi esidingekayo kanye nokukhetha kwewindi lesikhathi. Kufanele ihlolwe, ihlaziywe, futhi iqondwe izici zomthombo we-acoustic emission kanye nemithombo yomsindo yemvelo ngaphambi kokwenza ukukhetha okwanelisayo.
Ngesikhathi sokushisela, ngenxa yokuncibilika okukhulu kanye nokufakwa kwegesi kwento enamathela endaweni yokushisela, okuhambisana ne-spatter esigabeni sokuqala sokushisela, amasiginali amakhulu ohlobo lwe-acoustic emission akhiqizwa phakathi nomjikelezo wokuqala wokushisela, kodwa lezi zimpawu ziye zaba khona. okuncane okuphathelene nokwakheka kwe-weld nugget.
Ngakho-ke, iwindi lesikhathi kufanele lilungiswe kusengaphambili ukuze kungabikho zimpawu zokukhishwa kwe-acoustic ezitholwa phakathi nomjikelezo wokuqala. Esinye isici sokushisela amapuleti ensimbi athathiwe ukushisela amapuleti amakhulu e-amplitude acoustic emission at the late stage of spot welding, okubangelwa ukufakwa kwegesi kwe-zinc eyinsalela endaweni yokushisela. Ngalesi sikhathi, iwindi lesikhathi kufanele lilungiswe ukuze kuqedwe lezi zinsimbi ezinkulu zokukhishwa kwe-acoustic.
Leli windi lesikhathi kufanele livalwe ukuze kuvinjelwe ukukhiqizwa kokuqapha okungenangqondo. Ngokusekelwe kulobu buchwepheshe, ubudlelwano phakathi kobubanzi be-weld nugget kanye nesibalo samandla akhishwa yi-acoustic ngesikhathi sokushiselwa kwamapuleti ensimbi ayakhiwe.
