Middle assembling robot welding process for ship

Abstract

The invention discloses a middle assembling robot welding process for a ship. The middle assembling robot welding process comprises the following steps that a, preparation before welding is conducted, specifically, after a workpiece is moved to a welding position, the workpiece is checked; B, after the workpiece is in place, weld joints are positioned, and the welding sequence and the starting point and the ending point of each weld joint are determined; C, the angle of a welding gun is adjusted, the welding gun with a gooseneck part having a bending angle is adopted by the welding gun, reaches the starting points and the ending points of the weld joints, and flat fillet welding and vertical fillet welding are completed; D, after the welding is conducted for a certain time, welding gun cleaning, wire shearing and oil spraying procedures are started, and the welding gun is prevented from being blocked; and e, after the welding of all welding seam robots is completed, the appearance and size of the welding joints need to be detected. In the welding process, electric arc tracking is adopted, and automatic welding of straight angle and vertical fillet weld of the assembly component in the ship is achieved under the cooperative use of a specific robot welding posture, a welding process, a welding sequence and a swing mode.

Description

technical field [0001] The present invention mainly relates to the technical field of welding of structural components in ships, in particular to a robot welding process for assembly in ships, especially to a robot fillet weld GMAW welding process. Background technique [0002] As a major shipbuilding country in the world, China's current ship output ranks among the top three in the world, but the chronic problem of being too big but not strong is still very prominent. Shipbuilding technology, production efficiency, and quality levels are still lower than those of Japan and South Korea and other shipbuilding powers. In terms of technology, digitalization, automation, and integration, there are still many shortcomings that need to be filled, especially the core technology of the shipbuilding equipment system has been dominated and blocked by foreign suppliers. With the proposal of "Industry 4.0", the shipbuilding industry should vigorously develop towards automation and intel...

Problems solved by technology

Although the welding robot technology in the automobile manufacturing and other industries is relatively mature, and the shipbuilding has also used automatic welding machines to realize the automatic welding of long and straight welds in the process of panel assembly and group formation, but due to the irregular structure of the components and the There are various types of welds and complex welding paths. Robot welding technology cannot meet flexible and diverse welding requirements. At present, manual welding is mainly relied on.
