Suvirinamumas iš titano medžiagos priklauso nuo the chemical activity and physical properties of the material herself. At room temperature, the surface of titanium has a thin and dense oxide film with stable performance. As the temperature increases, the activity of titanium increases sharply. Kai suvirinimas temperatūra is aukštesnė nei 600 laipsnis , the tankus oksidas plėvelė is sunaikintas, ir dujos skarda difuzija į the interjeras iš the metal per the loose oxide film and mix with elements such as hydrogen, oxygen, and nitrogen. Violent chemical reaction occur, and these elements exist as interstitial impurities in titanium, causeing the performance of the welded joints, ypač the plastiškumas, to sumažėjimas. The presence of hydrogen is often the cause of pores and cold cracks in welding.
Prieš suvirinimas titanas medžiagos, the purvas, oksidai ir dujomis praturtintas metalas sluoksnis ant paviršius iš the ruošinys turėtų būti visiškai pašalintas per mechaninis valymas arba cheminis valymas.
