Adherence strength of metal coating plays an important role in workability of recovery shaft. This paper presents a Taguchi method combined Analysis of Variance (ANOVA) to optimize technological parameters for the adherence strength when restoring C45 steel shaft with a diameter of 100 mm by resistance welding using AISI 1070 filler wire. A set of welding parameters such as welding current (I h ), force (F), welding speed (V h ), is established to obtain the highest adherence strength. The optimal results have shown that the adhesion strength reaches the maximum value when the welding current, force, and welding speed are I h2 = 7.5 (kA), F 1 = 1.7 (kN), and V h1 = 1.5 (cm / s), respectively. This value is about 90% of parent metal strength; while the metal coating is still maintains hardness as its C45 steel with hardening (50-55HRC).
