Embodiment Construction

[0026] The self-propagating electrode based on electronic ignition includes a handle 1, a plug 2 and a medicine tube 3. The connecting end of the handle 1 has an external thread and is connected with the plug 2 through a thread. The boss of the plug 2 and the medicine tube The tube 3 is coaxially fixedly connected, and the other end of the medicine tube 3 is sealed with a sealing plug 5;

[0027] The handle 1 has a battery slot 6 and a switch slot 7. The two ends of the battery slot 6 are respectively a spring 10 and a metal sheet 11. The spring 10 and the metal sheet 11 are respectively connected to the two first contacts on the connecting end of the handle 1 through wires. Point 12 is connected, there are two corresponding second contacts 14 on the plug 2, when the handle 1 is connected with the plug 2, the first contact 12 is in contact with the second contact 14;

[0028] There is a 3-5mm igniting section 15 at one end of the inner plug 5 of the cartridge 3, and a flux 4 is fil...

Abstract

The invention belongs to the technical field of welding and relates to an electronic ignition based self-propagating welding electrode comprising a handle, an end cap, a flux tube, welding flux, and a packaging plug. The handle is provided with a battery cavity and a switch cavity. A spring and a metal plate are disposed at two ends of the battery cavity and are connected with two first contacts arranged at a connecting end, through wires respectively. The end cap is provided with two corresponding second contacts. When the handle is connected with the end cap, the first contacts are in contact with the second contacts. The packaging lug end of the flux tube is provided with an ignition segment 3-5mm long; space between the ignition segment and the end cap is filled with the welding flux; the head portion of an electronic ignition head covers the ignition segment; a wire of the electronic ignition head penetrates the welding flux and a wire hole of an end cap protrusion and is connected with the second contacts. A fuse of the welding electrode need not be ignited with a hand-held fire source during welding, and welding safety is higher; no fuse is exposed, and combustion of the welding electrode caused by contact with naked flame is also avoided; the welding handle is reusable.

Description

Technical field [0001] The invention belongs to the field of welding, and relates to a welding device, in particular to a self-propagating electrode based on electronic ignition. Background technique [0002] Welding technology is an important method for civil, engineering machinery and military equipment and manufacturing, emergency repair and emergency maintenance and installation. Traditional welding methods mainly use electric welding, gas welding, etc., but electrode arc welding requires a welding power source capable of outputting more than kilowatts and a heavy electric welding machine. Gas welding requires high-pressure special equipment that stores flammable gases such as oxygen and acetylene, which implicates engineering Large, and the operator must be specially trained. This greatly limits the mobile, flexible and efficient deployment of emergency welding and repair tasks in the field, power outages, rain and snow. In addition, these traditional emergency maintenance...
