Background

In order to solve the problem that the traditional welding method cannot be used under the extreme conditions that some energy sources are inconvenient to supply, such as high altitude, underground, underwater and the like, a plurality of scholars invest in the research of the field of the electroless welding rod and obtain some research results.

The utility model with the patent number of CN101444876B discloses a manual thermit welding rod and a preparation method and a use method thereof, the utility model with the patent number of CN102151982B discloses a portable welding pen, and the utility model with the patent number of CN102699521A discloses a simple electroless welding pen and a preparation method thereof. The igniters of the above patents all use exposed ignition wires for ignition. The firing sequence is lead → ignition charge → bulk welding agent. The advantage of above-mentioned design lies in convenient to use, and the part that ignites integrates in the welding rod itself, and every welding rod all can work independently, does not receive the restriction of other accessories. The disadvantage is that the ignition wire leaks, is easily broken or is subject to contamination failure (e.g., water) or accidental ignition (e.g., sparks). Meanwhile, due to the existence of a firing cable, the end part of the electroless welding rod is difficult to realize good sealing, and the internal medicine powder is in contact with the external air, so that the stability of the internal medicine powder is reduced.

The utility model with the patent number CN104096964B discloses a self-propagating welding rod based on electronic ignition, and the utility model with the patent number CN107442976B discloses a safety ignition device for electronic ignition of a non-electric welding rod. The two schemes are ignited by a special trigger, the trigger and the welding rod are respectively stored during storage, and the trigger and the welding rod are combined for use during use. The electronic ignition wire is buried in the welding rod, the trigger is powered to ignite the electronic ignition wire during ignition, and the ignition sequence is an electric ignition wire → ignition powder → main body welding agent. The ignition wire is arranged in the welding rod, the welding rod has good sealing performance, and the chemical agent is not polluted. And the igniter and the welding rod are stored separately, the welding rod cannot be ignited accidentally, and the safety is better. The disadvantage of the above solution is that it is relatively inconvenient to use and if the igniter fails, it results in the complete failure of multiple electrodes (this solution typically uses one trigger with multiple electrodes).
