Stamping parts have been widely used nowadays, and some stamping parts require welding treatment after shaping, in order for stamping processing plants to produce products that meet their application performance and shape forming requirements.

The welding of stamped parts is a processing method that achieves atomic bonding by heating or pressing, or a combination of both, with or without filling materials. Welding belongs to the category of detachable connections. There are four welding joint methods: butt joint, T-joint, corner joint, and lap joint. The joint size of welded workpieces is determined by the joint method, thickness, and groove method of the welded workpiece. The welding operated by electricians themselves is usually angle steel and flat steel, and generally does not have grooves. The welding methods for stamping parts are divided into four types: flat welding, vertical welding, horizontal welding, and overhead welding. Generally, different welding methods are selected based on their structure, shape, volume, and orientation. Among the four welding methods, the most chaotic one is overhead welding, which requires the shortest arc and smaller diameter electrodes during the process, making it very difficult.

When selecting flat welding for Metal Stamping parts, the weld seam is usually on a horizontal line, which is relatively simple to operate, and the diameter of the welding rod can also be larger, greatly improving production efficiency. The only disadvantage is that it is easy to present the phenomenon of mixed molten iron and slag that cannot be separated.

Because during the welding process of stamping parts, the melted metal flows downwards in vertical and horizontal welding, which can cause disadvantages. Therefore, at this time, stamping processing plants need to choose small-diameter welding electrodes and use shorter arcs for stamping part welding, and the welding current should also be one tenth smaller than usual.
