Abstract

The invention belongs to the field of welding, and relates to a process for welding between same metal plates or dissimilar metal plates, in particular to a method for welding between the metal plates. The method for welding between the metal plates comprises the following steps that, after the first metal plate and the second metal plate are in overlapped lap joint or butt joint, a proper amountof metastable self-propagating reaction metal mixed powder is placed at the lap joint or but joint position, welding is carried out, the self-propagating reaction of the metal mixed powder is triggered, and the first metal plate and the second metal plate are welded together with the aid of heat released by the self-propagating reaction. According to the method for welding between the metal plates, a large amount of heat generated during welding is utilized to trigger the metastable self-propagating reaction metal mixed powder for spontaneous reaction, and the first metal plate and the secondmetal plate are bonded together under the action of instantaneous heat released by the self-reaction. The method for welding between the metal plates is especially suitable for welding between the high-melting-point metal plates, and can overcome welding defects such as insufficient heat input of a high-melting-point alloy.

Description

technical field

[0001] The invention belongs to the field of welding, and relates to a welding process between metal plates of the same kind or different kinds of metal plates; in particular, it relates to a welding method between metal plates. Background technique

[0002] With the continuous development of automobile lightweight, people pay more and more attention to lightweight materials. Magnesium alloys and aluminum alloys not only have good corrosion resistance, but also have the characteristics of high specific strength, and have significant application prospects in the application of lightweight body materials. At present, many people have carried out research on the connection of aluminum-steel, magnesium-aluminum, and magnesium-steel. However, the joint strength is generally not high, and it is difficult to apply it to industrial practice. The research on the connection between the above dissimilar metals mainly focuses on methods such as fusion welding, brazing, ...
