FAQS

Q1: Arc welding ke eng?

Arc welding ke mokhoa o sebelisang mocheso o phahameng o hlahisoang ke arc ea motlakase ho qhibilihisa le ho kopanya lishiti tsa tšepe hammoho. Bakeng sa pipe e entsoeng ka spiral welded, mokhoa ona ke oa bohlokoa ho theha kamano e matla pakeng tsa liphaephe, e leng bohlokoa ho ts'ebetso le bophelo ba phala.
