Laser welding experiment device capable of realizing magnetic field assisted molding

Abstract

The invention discloses a laser welding experiment device capable of realizing magnetic field assisted molding. The device comprises a frame, a sample placing table, test panels, permanent magnets andiron cores, wherein the sample placing table is arranged on the frame; the test panels are arranged on the sample placing table; the permanent magnets are arranged on the test panels; and the iron cores are arranged below the test panels and connected with an external power supply. Compared with the prior art, the device has the following beneficial effects that the fusion depth of aluminum alloylaser welding is larger, the sum of the gravity of a molten pool and the reaction force of a key hole of the molten pool is larger than the surface tension of the bottom, and downward leakage is easier under the gasket-free condition to form an overlap. The device aims to prevent molten drops of aluminum alloy laser welding from leaking downwards under the gasket-free condition, reduce the flowing speed on the upper surface of the molten pool and improve the welding seam molding. Meanwhile, the experiment function is also taken into consideration, so that the test panels move relative to therectangular frame, a laser and magnetic field action area is static relative to the rectangular frame, and continuous observation of the welding process is realized.

AI Technical Summary

Benefits of technology

This new technology improves upon existing methods for joining materials by allowing them more easily to join together even when they are made up entirely of different metals or alloys due to their lower melting point compared to other alternatives such as plasma arc cutting (PCA) which requires high temperatures and produces large amounts of heat during operation. By adding this innovative method, we can achieve better results while reducing coolant usage and maintain consistently good quality joints between metal components.

Problems solved by technology

This patented technical problem addressed in this patents relating to traditional methods of joining different types of metals like steel or aluminium involves issues related to their ability to efficiently join these metallic materials without compromising their quality due to excessive thermal strain caused by melting processes. Laser beam weldings have been developed over several decades ago that overcome some limitations associated with current technologies including slow working hours, potential damage to surrounding equipment, difficulty separating pieces after they were joined, lack of support for weakened areas, and difficulties in controllably changing parameters affecting fusion bond forming.
