Soldering flux layered soldering pen

Abstract

The invention provides a soldering flux layered soldering pen. The soldering flux layered soldering pen comprises an explosive pipe, a clamping end and a pen container, wherein the clamping end and the pen container are connected to one end of the explosive pipe. The soldering flux layered soldering pen is characterized in that the explosive pipe is filled with a soldering flux; an ignition head is arranged at an end of the bottom of the explosive pipe; an ignition section is arranged between the ignition head and the soldering flux in the explosive pipe; the top of the explosive pipe is sealed by the clamping end; the inner part of the explosive pipe is of a double-layered pipe structure including an inner-layer explosive pipe and an outer-layer explosive pipe; the inner-layer explosive pipe is filled with a slag forming constituent and an alloying agent; and the outer-layer explosive pipe is filled with a thermite and a small amount of inner-layer explosive pipe soldering flux material. The soldering flux layered soldering pen is of a soldering flux layered explosive pipe structure, separates the slag forming constituent and the alloying agent from the thermite, and enables the reaction to be stable and reliable; meanwhile, a small amount of the slag forming constituents and a small amount of the alloying agents are added in the outer-layer explosive pipe with the thermite asthe main, so that the continuous thermit reaction is ensured; the slag forming constituent is mainly concentrated in the inner-layer explosive pipe, so that the absorption to the reaction heat is reduced, and a better protection effect on a molten pool is achieved; and the alloying agent is concentrated in the inner-layer explosive pipe, so that the trace alloy composition in a welding seam is adjusted more conveniently.

Description

technical field [0001] The invention belongs to the technical field of welding, and relates to a soldering pen, in particular to a flux layered soldering pen suitable for welding metal materials such as steel and copper. Background technique [0002] Welding technology is one of the important means for industrial, civilian machinery and military equipment manufacturing, emergency repair and emergency maintenance and installation, but the electrode arc welding commonly used at present requires a power supply with an output power of more than one kilowatt and a heavy electric welding machine, while gas welding needs to store oxygen The high-pressure special equipment for acetylene gas involves a lot of engineering, and the operator needs to receive special training. This greatly restricts the maneuverable, flexible and efficient deployment of emergency welding repair tasks under special circumstances such as power outages, outdoors, rain and snow. In addition, these tradition...

Problems solved by technology

During the reaction, the slagging agent mixed in the flux will increase the intensity of the reaction, absorb a large amount of heat, and reduce the heat input of welding; at the same time, the slag forming agent with a small content is dispersed in the high heat agent, and its protective effect is weakened
