FIller Metal Breakdown

S-6027.LF

S-6027.LF is an iron powder, iron oxide type electrode for single-pass horizontal and flat fillet welding. Its fume generation is reduced by 30~50% over conventional electrode. In manual welding, stable and beautiful bead can be obtained as contact welding is available. Furthemore, highly effective welding can be performed in Gravity and Acto-Contect Welding. Its slag removability is good. Resistibility against undercut and blow hole is also good. S-6027.LF demonstrates good performance in mechanical properties and usability..
