Low carbon steel welding rod for oxy-acetylene welding. It is a general purpose rod for welding low carbon steels and wrought iron with the required tensile strenght does not exceed 310 N/mm². Generally used for automotive repair works like tears and rips in the body or patching on badly damaged parts, joining steel sheets and plates, tubing and piping installation where and intense heat source is required for straightening, forming, preheating post weld heat treatment, regardless of the complexity and position in which welding has to be done. Weld metal has got good ductility and machinability. Welding shall be performed in neutral flame characteristics. It has got a fluid weld puddle.
