Premium Seamless Cored Wires

Diamondspark by Böhler Welding covers a full range of seamless cored wires to match the needs of demanding applications. Established in the market with a vast range of individual types are Böhler Welding tubular seamless cored wires (Diamondspark T-Line), which are manufactured by filling a tube with flux ingredients and drawing it to end diameter. Completely new are Böhler Welding types using a laser beam (Diamondspark L-Line) and drawing it to end diameter. Both fabrication routes allow subsequent copper-coating to give the cored wires optimal feeding characteristics and current transfer.
