The invention discloses a welding method which is characterized in that the method includes the following steps: selecting two or more base metals which are to be connected together, butt-jointing the to-be-connected parts of the base metals, preliminarily fixing the butt-jointed base metals and putting the base metals on a welding platform; holding the handle of a welding rod holder, aligning a welding gun with the joint of the two base metals and then start welding; keeping the angle between a welding wire and a welding side to be about 45 degrees in the welding process; and continuously and evenly shaking the handle of the welding rod holder. In this way, through the rotation of the nozzle of a weld crater, even and uniform decorative patterns can be formed in the weld crater, the weld crater moves forwards along the joint to form a weld joint so as to connect the two base metals, and the weld joint formed in this way has relevant patterns. The welding method has the technical effects of fast welding speed, nice-looking weld joint and enhanced reliability. When the method is used to weld stainless steel pieces, the steel pieces deform little in the welding process.
