Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to an automatic welding device for fillet welds. Background Art

[0002] A fillet weld is a weld formed along the intersection of two perpendicular or nearly perpendicular parts. This type of weld is formed by melting the welding rod and the metal at the joint at high temperature. The shape of the weld is beautiful and can be concave, flat or convex. Fillet welds are mainly divided into right-angle welds and bevel welds. A right-angle weld refers to a connection method in which the weld and the two welds form a 90-degree angle; while a bevel weld means that the angle between the weld and the two welds is less than 90 degrees. When welding two welds, a clamp is required to fix the welds and drive the welding device to move along the weld for welding.
