As tungsten is very sensitive to oxidation, brazing must be carried out under a protective gas, hydrogen, or in vacuum. If maximum strength of the joint is required, tungsten has to be brazed below its recrystallization temperature.
Bilang Tungsten ay napaka-sensitibo sa oksihenasyon, dapat na natupad pagpapatigas sa ilalim ng proteksiyon gas, hydrogen, o sa vacuum.
