The invention discloses a shielded metal arc welding method and a welding product, and relates to the field of relation welding, and a braking system comprises the steps that a bottom surface gap between a first base metal and a second base metal is controlled to be within a first distance range; a welding lining plate is arranged in a second distance range in the direction, deviating from the bottom surface, of the first base material and the second base material, and the projection of the welding lining plate and the projection of the welding seam in the thickness direction are overlapped; welding the base layer by using a welding rod with a first diameter in a way of split welding; welding rods of a second diameter are stacked and welded in a split welding mode to form the filling layer and the covering layer, and the second diameter is larger than the first diameter. 本申请公开了一种焊条电弧焊焊接方法及焊接产品，涉及关系焊接领域，该制动系统包括：控制第一母材和第二母材的底面间隙在第一距离范围内；在上述第一母材和第二母材的背离底面的方向上的第二距离范围上设置焊接衬板，上述焊接衬板与焊缝在厚度方向的上的投影交叠；以第一直径的焊条通过分道焊接的方式
