The invention relates to a production process of a clad steel wire rod with a steel core wire of a dual phase structure, which comprises the following steps: carrying out pretreatment on a copper belt and a steel core wire rod; cladding and wielding; drawing, wherein the steel core wire rod is made of low carbon steel the carbon content of which is less than or equal to 0.2%, or made of low carbon steel the contents of manganese and vanadium of which are respectively less than or equal to 0.2%, and less than or equal to 0.12%; carrying out double phase heat treatment on drawn wire rod, wherein the double phase heat treatment is carried out on the drawn wire rod, and enables the temperature of the drawn wire rod to be 740-950DEG C; and then rapidly cooling so as to enable the steel core wire rod to obtain the double phase structure of ferrite and martensite. The clad steel wire rod has high strengthen, tensile strength which can be 600-1000MPa, and good elongation percentage which can be over 15%, and when in
