Abstract
The invention discloses a multilayer multipass welding method for horizontal position welding of a groove weld robot, and relates to the technical field of welding. According to the welding method, a datum body with one surface as the plane is welded to a groove, and therefore welding operation space is increased, an initial pass welding body, at least one middle pass welding body and a tail pass welding body are sequentially welded to the surface of the datum body from the first welding face of the groove to the second welding face of the groove, welding quality is ensured, the first layer welding working procedure is completed, and finally, according to the same manner, multilayer welding working procedures can be sequentially completed upwards in the groove depth direction until the groove weld is filled and leveled up; postures of three robot welding guns are only adopted, the welding working procedure of the groove can be completed, robot welding gun control programming work can be correspondingly reduced, in addition, due to adoption of the multipass multilayer welding manner, the welding quality can be further ensured.
Description
technical field [0001] The invention relates to the technical field of groove welding, in particular to a multi-layer and multi-pass welding method for robot horizontal welding of groove welds. Background technique [0002] Robot automatic welding technology is widely used in many fields such as automobile production, shipbuilding, parts production, electronic and electrical manufacturing, etc., and occupies a leading position in related industries. It has stable and reliable welding quality, high production efficiency, low production cost and It is convenient for modern management and other advantages. [0003] When using robot automatic welding technology for weld seam welding of steel plates with a thickness of more than 100mm, the robot needs to adapt to the weld bevel type and complete multi-layer and multi-pass welding at the weld bevel. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the...
