Technology of Drill Rod
Drill rods are widely used in water well drilling, mining, quarry,etc. We use seamless steel tube to produce the drill rods and carry on heat treatment of materials, internal thickening technology, tempering process after friction welding. Friction welding is the important process to manufacture the drill rods. It is solid-state joining technique that welds workpieces by generating heat through mechanical friction. We have the powerful friction welding machine that imported from South Korea to produce the high quality drill rods.
