Bidirectional laser welding system and bidirectional working method

Abstract

The invention provides a bidirectional laser welding system. The bidirectional laser welding system comprises a first steel structure, a laser head, a first working machine table, a second working machine table and a control device; the first steel structure is provided with a laser head walking shaft parallel to ground; the laser head is arranged to move along the laser head walking shaft; a reference line is arranged at the middle point of the laser head walking shaft, is perpendicular to the laser head walking shaft and is parallel to the ground; a plane passing through the reference line and perpendicular to the ground is defined as a second reference plane; the first working machine table and the second working machine table are the same in structure; and the first working machine table and the second working machine table are symmetrically arranged relative to the second reference plane. The bidirectional laser welding system provides two working machine tables, when one working machine table completes the welding procedure, the other working machine table completes the part discharging and feeding procedures, and therefore the laser head can be in a full-load working state, and the double capacity can be achieved.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to a bidirectional laser welding system and a bidirectional working method. Background technique [0002] Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. The intensity of the laser beam emitted by laser welding is high, and the local temperature is high. Once an accident occurs, the damage caused is very serious. In addition, the weldments involved in the welding process are heavy, and manual alignment and s...

Problems solved by technology

[0003] Even if automatic production is adopted, since the welding process is carried out sequentially, for example, the laser head is in a standby state when the welding piece is being loaded, which obviously causes a great waste of production capacity
