Ka pele ho boqapi bona ke theknoloji ea rona e tsoetseng pele ea ho Welding ea Arc (SAW), mokhoa o ratoang bakeng sa phaephe e qhibilihisitsoeng ka moea o pota-potileng. Theknoloji ena e netefatsa ho nepahala, ho tšoarella le katleho, e leng se etsang hore e be e loketseng liindasteri tse itšetlehileng ka phaephe e qhibilihisitsoeng ea boleng bo holimo.
