Loaʻa iā ia ka ikaika kiʻekiʻe a me ka paʻakikī, ka conductivity uila a me ka conductivity thermal, ke kūpaʻa maikaʻi a me ka hōʻemi ʻana i ka lole.Ma hope o ka mālama ʻana i ka wā kahiko, hoʻomaikaʻi maikaʻi ʻia ka paʻakikī, ka ikaika, ka conductivity uila a me ka conductivity thermal, a ua maʻalahi ke weld.Hoʻohana nui ʻia i nā kaʻa commutators, spot welders, seam welders, electrodes no butt welders, a me nā ʻāpana ʻē aʻe e koi ai i ka ikaika, paʻakikī, conductivity, a me nā waiwai pad i nā wela kiʻekiʻe.Hiki ke hoʻohana ʻia ka uila uila uila e hoʻopaʻa i kahi aniani aniani maikaʻi, a i ka manawa like, loaʻa iā ia ka hana kūpono kūpono, a hiki ke hoʻokō i nā hopena paʻakikī e hoʻokō me ke keleawe ʻulaʻula maʻemaʻe e like me nā ʻāpana lahilahi.Hana maikaʻi ia ma nā mea paʻakikī i ka mīkini e like me ke kila tungsten.
