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

Abstract

The invention provides a flux layered soldering pen, which includes a drug tube, a clamping end connected to one end of the drug tube and a pen holder. There is an ignition section between the head and the flux in the drug tube, and the top of the drug tube is sealed by the clamping end. The inside of the drug tube is a double-layer tube structure, which is an inner layer drug tube and an outer layer drug tube, and the inner layer drug tube is filled Slagging agent, synthetic agent, high heat agent filled in the outer layer of drug tube and a small amount of flux material in the inner layer of drug tube. The invention adopts the flux layered drug tube structure to separate the slagging agent, alloying agent and high-heat agent, so that the reaction is stable and reliable; at the same time, a small amount of slagging agent and alloying agent are added to the outer drug tube mainly composed of high-temperature agent , to ensure the continuous progress of the thermite reaction; the slagging agent is mainly concentrated in the inner drug tube, which reduces the absorption of reaction heat and plays a better role in protecting the molten pool; the alloying agent is concentrated in the inner drug tube, which is more convenient Adjust the trace alloy composition in the weld.

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...
