Busur iku alus lan stabil, kurang cipratan, mbentuk ayu, aman slag apik.
Kurang soot, karo kinerja proses welding banget.
Logam gabungan ngandhut Cu, Ni, Cr, supaya resistance karat atmosfer apik, resistance mecah banget.
Tianshu Xing, operator gas alam cair (LNG) gedhe kanthi 174.000 meter kubik, dibangun minangka busur.
