Multifunctional welding equipment and method for continuous rolling

Abstract

The invention belongs to the field of welding correlation technology, and discloses a multifunctional welding equipment and method for continuous rolling. The multifunctional welding equipment for continuous rolling comprises a vertical transmission mechanism, a laser welding connector, an electric arc welding gun, a connecting seat and a machine frame, the vertical transmission mechanism is arranged on the machine frame, and the laser welding connector is arranged on the vertical transmission mechanism; the connecting seat is arranged on the machine frame, and the electric arc welding gun isconnected to the connecting seat; and the laser welding connector comprises a second cavity body and two reflecting mirror modules, the second cavity body is connected with the vertical transmission mechanism, the two reflecting mirror modules are separately and detachably arranged on the second cavity body, the two reflecting mirror modules are used for changing the light path transmission direction of a laser beam entering the second cavity body, and the laser beam is reflected by the two reflecting mirror modules and incident perpendicularly on the surface of a piece to be welded. The multifunctional welding equipment for continuous rolling improves production rhythm, functions are complete, and the structure is compact.

Description

technical field [0001] The invention belongs to the technical field related to welding, and more specifically relates to a multifunctional welding equipment and welding method for continuous rolling. Background technique [0002] The process of continuously and uninterruptedly manufacturing coils through the continuous rolling technology of steel strips is a key technology for improving competitiveness, saving energy and reducing consumption. Since the rolling tension in the whole process remains unchanged, the production rhythm is greatly improved, and it is widely used in the production of steel products. The core of the continuous rolling technology of steel strip is to solve the problem of balance between weld toughness and strip rolling tension. . At present, according to the different types of steel, the most commonly used welding forms are arc welding, laser welding and laser-arc hybrid welding. Among them, the arc root drift under high-speed conditions makes the wel...

Problems solved by technology

Due to the limited space, the laser welding head cannot use the conventional horizontal or vertical incident laser, or needs to use a focusing lens with a small focal length. At this time, the protective lens at the bottom of the laser welding head is closer to the strip surface. When welding thick plates, strong The spatter makes the protective lens in the laser welding head consumed quickly, increasing the cost of the enterprise
