Bi welding HF an welding bi kemerê binê avê boriyê bi lûleyên pola re gêr dike. Makîneya çêkirina lûleyên welded ji uncoiler, makîneya astkirinê, welderê qûnê, lûk, makîneya rastkirinê û alavên frekansa bilind pêk tê. Xeta hilberîna meya nûjen û her yekîneyek xeta hilberînê ne tenê aborî lê di heman demê de pratîk jî ne. Xeta hilberînê ya bêkêmasî dema ku boriyek dor hildiberîne teknolojiya ZTF qebûl dike, xerîdar dê% 60 lêçûn li ser amûrkirinê kêm bike.
