The invention discloses a preparation method of potassium titanate and application of the potassium titanate in an electric welding rod, and belongs to the technical field of potassium titanate. The method comprises the following steps: by taking potassium oxide and titanium dioxide as raw materials and KCl-KF as a cosolvent, uniformly mixing the materials, adding into a polypropylene solution, carrying out wet grinding treatment, sintering, and carrying out post-treatment to obtain the potassium titanate. In the preparation of potassium titanate, a polypropylene solution is added into the material, and slurry grinding is performed, so that the mixing degree of the raw materials is increased; the potassium titanate is applied to preparation of the welding electrode, the arc voltage of the welding electrode is stable, the dust generation amount is low, the sulfur content and the phosphorus content are both smaller than 0.015%, and the overall performance is excellent. 本发明公开了一种钛酸钾的制备方法及其在电焊条中的应用，属于钛酸钾技术领域。该方法以氧
