FAQ
Asɛmmisa: Sɛ manyi galvanized coating no ansa na mayɛ welding a, dɛn na ɛba?
A: Sɛ wɔannyi zinc a wɔde akata so no ansa na wɔayɛ welding no a, ebetumi ayɛ vaporize bere a wɔreyɛ welding no, na ama wusiw a awuduru wom aba na ɛde efĩ aba weld no mu. Eyi betumi ama welds a ɛyɛ mmerɛw na ɛyɛ mmerɛw aba.
Asɛmmisa: So metumi de welding kwan biara adi dwuma de weld galvanized dade?
