The weld seams have a coarse-grained structure in the hot-fusion zone, owing to recrystallization, and can therefore withstand only low mechanical stresses. Tungsten can be welded by tungsten inert gas (TIG) welding, laser beam welding (for thin parts), plasma welding, friction welding and electron beam welding, the latter being the preferred fusion-welding method. Tungsten can be welded to W-Re and Mo-Re alloys. W-Re alloys (in particular W-26Re) are recommended as filler metal for welding tungsten.
Ang pag-isahin seams magkaroon ng isang magaspang istruktura sa hot- fusion zone, sanhi sa recrystallization, at maaari samakatuwid mapaglabanan lamang mababa mechanical stresses . Tungsten maaaring welded sa pamamagitan ng Tungsten hindi gumagalaw na gas (TIG) hinang, laser beam hinang (para sa manipis na bahagi), plasma hinang, hinang alitan at elektron ngumiti hinang, sa huli pagiging ginustong pamamaraan ng pag-iisa - hinang . Tungsten maaaring welded sa W- Re at Mo - Muling alloys . W- Muling alloys (sa partikular W- 26Re) ay inirerekomenda bilang tagapuno ng metal para sa hinang Tungsten . Tungsten maaaring maging pagsasabog welded sa Tungsten at iba pang mga riles .
