Problems solved by technology

[0004] Because it is difficult to realize the tapping process on amorphous alloy materials, it is difficult to realize the structure of bolts and nuts on amorphous alloy products. Moreover, if adhesives are used to bond bolts and nuts to amorphous products, the connection strength does not meet the needs of production

Abstract

The invention relates to the technical field welding of amorphous alloy, in particular to a resistance welding method for the amorphous alloy. The resistance welding method for the amorphous alloy comprises the steps that the base metal amorphous alloy and welding workpieces are welded, the amorphous alloy and the welding workpieces make contact with each other, after the amorphous alloy and the welding workpieces are connected with electrodes respectively, the electrodes apply pressure, resistance heat generated through currents is utilized for heating the amorphous alloy and the welding workpieces to exceed respective melting points or to reach respective supercooled liquid phase regions, a TTT drawing serves as a standard, and the welding workpieces and the amorphous alloy are welded under the condition that a crystallization reaction does not occur. The welding workpieces contain one or more elements contained in the amorphous alloy. The welding method solves the problem that tapping is hard to carry out on the amorphous alloy, achieves joint of the amorphous alloy and the welding workpieces quite well, the intensity of the welding positions between the amorphous alloy and the welding workpieces is made to be quite high, and the welded amorphous alloy still maintains an amorphous structure.

Description

Technical field [0001] The invention involves the field of welding technology of amorphous alloys, especially the resistance welding method involving an amorphous alloy. Background technique [0002] Due to the excellent characteristics of intensity, hardness, toughness, wear resistance, corrosion resistance, soft magnetism and superconductivity, it has been widely used in electronics, machinery, chemical industry and other fields.However, although the amorphous alloy has the excellent characteristics of the above, there are shortcomings of difficulty processing and difficult welding, which greatly limits its application scope.Therefore, the welding of amorphous alloys has become a technical difficulty of an amorphous alloy application expansion. [0003] Due to the unreasonable welding method, the existing technologies often occur in non -crystal alloy crystallization due to unreasonable welding methods, resulting in in -depth promotion and application of amorphous alloys.
