Avesta P5-VDX description: AVESTA P5-VDX is a highly alloyed low carbon electrode. It is designed for dissimilar welding between stainless and mild or lowalloy steels but can also be used for overlay welding providing an 18 Cr 8 Ni 2 Mo type deposit from the very first layer. P5-VDX has an extra thin coating, providing an excellent weldability when welding thin plates in the vertical-down position, e.g. corner welds, butt welds and overlap welds.
