What welding wire do 15CrMo and 1Cr5Mo use?
If the crack resistance is good, the ER309 or nickel based wire can be used
Welding wire, H05CrMoTiR welding rod, R307, welding wire, H13CrMo welding rod, R307, or welding wire, TIG-R40 welding rod, R507
1cr5Mo and 15CrMo are welded with R207, R307, R407, R317 or A407 electrodes (according to the welding procedures for petrochemical heterogeneous steels, SHT, 3526-2004>>). 1cr5Mo is a class five material, 15CrMo is the four kind of material.The basic principle of electrode selection: there are many kinds of electrodes, each of which has certain characteristics and uses. In order to ensure product quality, improve production efficiency and reduce production costs, the electrode must be selected correctly. In the actual selection of electrode, in addition to considering the economy, construction conditions, welding efficiency and labor conditions, we should also consider the following principles:Principle of equal strength: for the workpiece or structure which is subjected to static load or general load, the welding rod is usually chosen according to the principle of strong welding and base material, that is, the tensile strength of welding seam is equal or close to that of base metal.Principle of equal condition: the welding rod is selected according to the working conditions and characteristics of the workpiece or welding structure. For example, when welding is subject to dynamic load or impact load, the basic electrode with higher impact toughness should be chosen, but the welding electrode can be used in the welding structure.Principle of equality: welding structures under special conditions, such as corrosion resistance, high temperature or low temperature, etc., in order to guarantee the performance, the welding rod shall be selected according to the same or similar principle of the deposited metal and the base metal.
