Novel welding rod and preparation method thereof

Abstract

The invention relates to a novel welding rod and a preparation method of the novel welding rod. The welding rod is prepared by performing crushing, gelling, extrusion molding and driving dissolution on nitrocotton, a thermite, a slag former and a stabilizer. According to the welding rod, the surfaces of a solder and welding parent metal are melted, by utilizing heat produced by the combustion of the nitrocotton and the thermite, to form atomic bonding between the welding parent metal and the solder and further realize welding. In the whole welding process, any external energy source or special welding equipment are not required, so that the welding operation is greatly facilitated. The welding rod can be applied to a bumpy combat environment of a battlefield, and is unlikely to break by vibration, and even though the welding rod is broken, the combustion performance of the welding rod is still kept unchanged, and the welding rod still can effectively realize welding; and moreover, the welding rod has a non-powdery internal structure, so that a deflagration phenomenon caused by vibration can be avoided in the combustion of the welding rod.

Description

technical field [0001] The invention relates to a novel welding rod and a preparation method thereof. technical background [0002] With the rapid development of intelligent and high-energy ammunition, battlefield equipment is extremely vulnerable to long-range precision strikes. The strength of emergency repair capabilities of battlefield equipment is one of the important factors that determine the success or failure of a war. Research statistics show that the damage of metal components of battlefield equipment accounts for more than 80% of all damaged components, and most of the damaged components need to be repaired by welding. In addition, with the continuous warming of the global climate, various extreme weathers occur from time to time, which have a certain destructive effect on industrial facilities and civil equipment. For example, in 2008, extreme freezing weather occurred in southern my country, which caused serious damage to basic power facilities. Most of its rep...

AI Technical Summary

Problems solved by technology

Traditional welding methods such as manual arc welding, gas welding, and newly developed laser welding and electron beam welding, etc., cannot be performed conveniently anytime, anywhere due to limitations in welding energy, welding equipment, and welding processes.

It is precisely because of these limitations that traditional welding methods can no longer meet the requirements of emergency repairs on the battlefield and emergency rescue of civilian facilities.
