Abũbuwan amfãni da rashin amfani na Laser Welding na Aluminum Alloy

A lokacin da Laser waldi aluminum gami, kamar waldi na galvanized karfe farantin, da yawa pores da fasa za a samar a lokacin waldi tsari, wanda zai shafi waldi quality.Aluminum kashi yana da low ionization makamashi, matalauta waldi kwanciyar hankali, kuma zai haifar da katsewar waldi.Bugu da ƙari, hanyar yin walda mai zafi mai zafi, aluminum oxide da aluminum nitride za a samar a cikin dukan tsari, haifar da gurɓataccen yanayi.

Duk da haka, aluminium gami farantin surface za a iya goge kafin waldi don ƙara ta sha na Laser makamashi;Za a yi amfani da iskar gas mara ƙarfi yayin walda don hana ramukan iska.

Laser baka matasan waldi na aluminum gami ya warware matsalolin Laser waldi ikon, sha na Laser katako a saman aluminum gami da kofa darajar zurfin shigar azzakari cikin farji waldi.Yana daya daga cikin mafi alamar al'ada aluminum gami waldi tafiyar matakai.A halin yanzu, tsarin bai balaga ba kuma yana cikin mataki na bincike da bincike.

Wahalhalun walda na Laser ya bambanta don nau'ikan allo na aluminum daban-daban.The marasa zafi magani ƙarfafa aluminum da aluminum gami 1000 jerin, 3000 jerin da 5000 jerin da kyau weldability;4000 jerin gami yana da ƙarancin ƙima sosai;Don jerin gami 5000, lokacin da ω Lokacin (Mg) = 2%, gami yana haifar da fasa.Tare da haɓaka abun ciki na magnesium, aikin walda yana inganta, amma ductility da juriya na lalata sun zama matalauta;2000 jerin, 6000 jerin da 7000 jerin gami da babban hali zuwa zafi fatattaka, matalauta weld samuwar, da kuma gagarumin raguwa a post weld tsufa taurin.

Saboda haka, ga Laser waldi na aluminum gami, shi wajibi ne don dauko dace matakan tsari da kuma daidai zabi waldi hanyoyin da matakai don samun sakamako mai kyau waldi.Kafin waldi, saman jiyya na kayan, kula da walda tsarin sigogi da kuma canji na waldi tsarin ne duk tasiri hanyoyin.

Zaɓin sigogin walda

· Ikon Laser 3KW.

· Gudun waldawar Laser: 4m/min.Gudun waldi ya dogara da yawan kuzari.Mafi girma yawan ƙarfin kuzari, da sauri da saurin walda.

· Lokacin da farantin galvanized (kamar 0.8mm na gefen bango na waje farantin da 0.75mm don saman murfin waje farantin), da yarda da taro da ake sarrafawa da cibiyar, kullum 0.05 ~ 0.20mm.Lokacin da weld ɗin ya kasance ƙasa da 0.15 mm, ba za a iya cire tururin zinc daga ratar gefen ba, amma an cire shi daga farfajiyar weld, wanda ke da sauƙin samar da lahani na porosity;Lokacin da faɗin walda ya fi 0.15 mm, narkakkar ƙarfe ba zai iya cika gibin gaba ɗaya ba, wanda ke haifar da ƙarancin ƙarfi.Lokacin da kauri na weld daidai yake da na farantin, kayan aikin injiniya sune mafi kyau, kuma nisa weld ya dogara da diamita na mayar da hankali;Zurfin walda ya dogara da yawan kuzari, saurin walda da diamita mai da hankali.

· Gas mai karewa shine argon, ya kwarara shine 25L / min, kuma matsa lamba na aiki shine 0.15 ~ 0.20MPa.

· Mayar da hankali diamita 0.6 mm.

· Matsayin mayar da hankali: lokacin da kauri na farantin ya kasance 1mm, mayar da hankali kawai akan saman saman, kuma matsayi na mayar da hankali ya dogara da siffar mazugi.
