2005: Application engineering report „Cleaning and Lubrication of Welding Wire“


Non-metallic impurities affect the weldability and feedability of welding wires. For smooth welding of high-alloy welding wires, a dead surface without drawing residuals have been proven beneficial. To achieve this, the wire should be cleaned after drawing. Using our Helicord system, impurities can be reduced by up to 70 %.
By lubricating the wire, the coefficient of friction is reduced and feedability is enhanced. Wax-like lubricants and oils with additives, that also enhance weldability, seem to be most valuable. Contrary to trials with other lubricating systems which did not achieve any satisfactory performance, Helicord met or even exceeded the requirements of several manufacturers of welding wire.
