Flash welding ne yafi amfani da workpiece counterpart lamba juriya samar da zafi dumama workpiece, karfe farfajiyar narkewa, zazzabi gradient ne mai girma, zafi tasiri yankin ne karami.
Welding seams ne a karkashin yanayin samar da filastik deformation karfe karfe, samar da al'umma hatsi. Welding suture tsari, abubuwa kusa da asali karfe (ko bayan zafi magani), mafi sauki don samun irin ƙarfin isoplastic walda haɗi.
Tsarin flash yana da aikin kare kansa na fitar da iska, rage karfe oxidation. Top Forging kuma iya fitar da oxide daga walda seams tare da ruwa karfe. Kawai ƙarancin lalacewar da aka haɗa da waldi, ba waldi ba.
Tsarin walƙiya yana da ƙarfin aikin daidaitawa, ƙananan buƙatun daidaitawa don tsananin kiyaye ƙa'idodin ƙa'idodi, da ingancin walda mai kwanciyar hankali. Unit walda sashe yankin bukatar lantarki ikon karami, walda low carbon karfe bukatar kawai (0.1-0.3) KVA / mm2 lantarki ikon.
Welding yawan aiki ne mai girma, walda daya haɗi kawai dauki 'yan dakika zuwa 'yan dakika.
Wide kewayon walda aikace-aikace, a ka'ida za a iya forging karfe kayan za a iya walda da flash a walda. Misali, ƙarfe mai launi da ƙarfe masu launi kamar ƙarfe mai ƙarancin carbon, ƙarfe mai ƙarancin carbon, ƙarfe mai haɗin gwiwa, bakin ƙarfe da ƙarfe masu haɗin gwiwa za a iya walda su ta hanyar walda.
Welding sashe yankin kewayon ne mai girma, yawanci daga dubun-dubun mm2 sashe yankin za a iya welding.
Flash walda da yawa amfani da walda daban-daban bangarori, bututun kayan aiki, profile, m sassa, wuta kayan aiki, da dai sauransu, aikace-aikace ne sosai m, shi ne wani tattalin arziki, high inganci walda hanya.
1) Shirin sarrafawa rage ƙarfin lantarki flash don walda Wannan walda hanyar halaye ne, da flash fara mataki amfani da mafi girma na biyu m ƙarfin lantarki don taimakawa tashi flash, a lokacin da karshen fuskar zafin jiki ya tashi, sa'an nan amfani da low ƙarfin lantarki flash, da kuma kiyaye flash gudun m don inganta zafi inganci. Lokacin da kusa da saman forging, sa'an nan haɓaka biyu ƙarfin lantarki, sa flash karfi don ƙara kansa kariya tasiri.
Tsarin sarrafawa na rage ƙarfin lantarki na walda na walda idan aka kwatanta da walda na walda na walda na walda, yana da gajeren lokacin walda, ƙananan ƙarfin da ake buƙata, da kuma amfanin dumama daidai.
2) A siffar wannan walda hanyar da pulse flash-walda ne, a lokacin da motsi clipper shigar da tafiya, ta hanyar na'urar motsi mai aiki da karfin ruwa rawar jiki na'urar, sa'an nan overlay wani shugabanci rawar jiki tafiya, amplitude ne 0.25-1.2mm, mitar ne 3-35Hz daidaitacce daidaitacce. Saboda rawar jiki ya sa walda karshen fuskar juyawa da kuma jawo, saboda haka samar da pulse flash.
An kwatanta da walda da walda na yau da kullun walda na walda, saboda babu fashewar da ba ta da kyau ba, ƙananan ƙwayoyin spraying da wuta ba su da wuta, don haka zafi na iya ƙara fiye da sau biyu, da kuma ƙididdigar ƙirar sama za a iya rage zuwa 2/3-1/2.
Hanyoyin biyu a sama sun fi dacewa da buƙatun walda na flash na manyan sassan aiki.
3) rectangular wave flash walda Wannan walda hanyar idan aka kwatanta da masana'antu mita AC sine wave flash walda, zai iya muhimmanci inganta flash kwanciyar hankali. Saboda wutar lantarkin sine wave lokacin da ƙarfin lantarki ya kusa da sifili zai sa walƙiya ta katse nan da nan, yayin da walƙiyar rectangular za ta iya samar da walƙiya daidai a duk lokacin. Ba da alaƙa da ƙarfin lantarki mataki.
A rectangular wave wutar lantarki naúrar lokaci lambar flashes ne 30% mafi girma fiye da aiki mita canji, sprayed karfe particles ƙananan, wuta haske, thermal inganci high. Ana iya daidaita mitar watsi mai daidaito a cikin kewayon 30-180Hz. Wannan hanyar ne mafi yawan amfani da ci gaba da flash-to-walda na fina-finai da kuma aluminum gami ƙafafun.
