Hanyoyin walda na yau da kullun don titanium da titanium gami sun haɗa da: argon arc waldi, waldawar baka mai nutsewa, walda injin katako, da sauransu.
Shiri kafin walda
Ingancin yanayin walƙiya da waya waldi na titanium yana da babban tasiri akan kayan aikin injiniya na haɗin gwiwar welded, don haka dole ne a tsaftace shi sosai.
1) Tsaftace Injini: Don walda waɗanda baya buƙatar ingancin walda ko kuma suna da wahalar tsinke, ana iya amfani da takarda mai kyau ko gogayen waya na bakin karfe don goge su, amma yana da kyau a yi amfani da rawaya carbide don goge farantin titanium don cirewa. fim din oxide.
+ Maganin pickling na iya zama HF (5%) + HNO3 (35%) maganin ruwa. Kurkura da ruwa mai tsabta bayan picking, kuma weld nan da nan bayan bushewa. Ko amfani da acetone, ethanol, carbon tetrachloride, methanol, da dai sauransu don goge tsagi na farantin titanium da bangarorin biyu (a cikin 50mm kowannensu), saman wayar walda, da kuma ɓangaren da kayan aikin ke hulɗa da farantin titanium.
3) Zaɓin kayan aikin walda: Don waldawar argon arc na titanium da faranti na tungsten tungsten, tushen wutar lantarki na DC argon arc tare da halayen waje da haɓakar arc mai girma ya kamata a zaɓi, kuma jinkirta isar da iskar gas bai kamata ya zama ƙasa da ƙasa ba. 15 seconds don guje wa oxidation da gurɓataccen walda.
4) Selection na walda kayan: The tsarki na argon gas ya kamata ba kasa da 99.99%, da dew batu ya zama kasa -40 ℃, da kuma jimlar taro juzu'i na impurities ya zama 0.001%. Lokacin da matsa lamba a cikin silinda argon ya ragu zuwa 0.981MPa, ya kamata a dakatar da shi don hana rinjayar ingancin haɗin gwiwa.
Kayan aikin walda na Xinfa yana da halaye masu inganci da ƙarancin farashi. Don cikakkun bayanai, da fatan za a ziyarci:Welding & Yanke Manufacturers - China Welding & Yanke masana'anta & Suppliers (xinfatools.com)
5) Kariyar iskar gas da zafin walda: Ƙwararren bututun titanium yana da ƙasa a lokacin walda. Don hana haɗin welded daga gurɓatar da iskar gas da abubuwa masu cutarwa a yanayin zafi mai zafi, yankin walda da walda dole ne a sanya kariya ta walda da kuma kula da zafin jiki, kuma zafin jiki ya zama ƙasa da 250 ℃.

1. Lokacin yin walƙiya argon baka na hannu, ƙaramin kusurwa (10 ~ 15 °) yakamata a kiyaye tsakanin wayar walda da waldawa. Ya kamata a ciyar da wayar walda a cikin narkakkar tafki a hankali kuma a ko'ina tare da ƙarshen gaban narkakken tafkin, kuma ba za a motsa ƙarshen wayar daga yankin kariya na argon ba.
2. Lokacin waldawa, bindigar walda a zahiri baya lilo a kwance. Lokacin da yake buƙatar juyawa, mita ya kamata ya zama ƙasa kuma kada ya zama girman girma don hana cutar da kariya ta iskar argon.
3. A lokacin da karya da baka da kuma gama weld, ci gaba da wuce argon kariya har sai weld da karfe a cikin zafi-shafi yankin sanyi zuwa kasa 350 ℃ kafin cire walda gun.
