Embodiment Construction

[0027] The self-propagating welding rod based on electronic ignition includes a handle 1, a plug 2 and a drug tube 3. The connecting end of the handle 1 has an external thread, and is connected with the plug 2 through threads, and the boss of the plug 2 is connected to the drug tube. The tubes 3 are fixedly connected coaxially, and the other end of the drug tube 3 is sealed with a packaging plug 5;

[0028] The handle 1 has a battery slot 6 and a switch slot 7, and the two ends of the battery slot 6 are respectively a spring 10 and a metal sheet 11. Point 12 is connected, there are two corresponding second contacts 14 on the plug 2, when the handle 1 is connected to the plug 2, the first contact 12 is in contact with the second contact 14;

[0029] There is a 3-5mm long ignition section 15 at one end of the sealing plug 5 of the drug tube 3, and welding flux 4 is filled between the ignition section 15 and the plug 2, and the drug head part of the electric ignition head 16 is w...

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

[0001] technical field [0002] The invention belongs to the field of welding, and relates to welding equipment, in particular to a self-propagating electrode based on electronic ignition. Background technique [0003] Welding technology is an important means of civil, construction machinery and military equipment and manufacturing, rush repair and emergency maintenance and installation. Traditional welding methods mainly use electric welding, gas welding, etc., but electrode arc welding requires a welding power supply capable of outputting more than a kilowatt and a heavy electric welding machine, while gas welding requires high-voltage special equipment for storing flammable gases such as oxygen and acetylene, which involves extremely high engineering costs. Large, and the operator must receive special training. This greatly limits the flexible, flexible and efficient deployment of emergency welding repair tasks in the field, power outages, rainy and snowy weather and o...
