Description

Technical Field

[0001] This utility model belongs to the field of welding and cutting technology, specifically relating to a flammable underwater welding and cutting bar. Background Technology

[0002] Underwater welding cutting rods ignite an electric arc between the tip of the cutting rod and the metal being cut. The high temperature generated by the arc heats the metal to its ignition point. At the same time, a high-pressure oxygen stream is sprayed into the cutting area through the channels inside the cutting rod, causing the metal heated to its ignition point to oxidize violently. The generated oxides are blown away by the high-pressure oxygen stream, forming a kerf. As the cutting rod moves, the continuous kerfs cut the metal, achieving the cutting purpose.

[0003] Due to the complexity of the underwater environment, the presence of water can greatly affect the stability and safety of the welding and cutting process. Currently, welding and cutting electrodes are difficult to ignite and burn stably and continuously underwater, which can easily lead to interruptions in the welding or cutting process and excessively long ignition time, affecting work efficiency and quality. Therefore, a flammable underwater welding and cutting electrode is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a flammable underwater welding and cutting electrode that can stably ignite and burn in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A flammable underwater welding and cutting electrode includes multiple flux cores and a wrapping component sleeved on the flux cores, and further includes:

[0007] Copper-plated heads are disposed at both ends of the drug core;

[0008] A flammable coating is disposed at one end of one of the cores.

[0009] As a further optimization of this utility model, the cores are arranged in a ring array, and multiple cores form oxygen outlet holes.

[0010] As a further optimization of this utility model, the package includes a polytetrafluoroethylene tube, a metal layer and a waterproof layer, which are sequentially sleeved on the drug core from the inside out.

[0011] As a further optimization of this utility model, the copper plating heads have different lengths, with the longer copper plating head connected to the welding gun.

[0012] As a further optimization of this utility model, the longer copper-plated head and tail ends are hollow.

[0013] As a further optimization of this utility model, a combustion-supporting agent is added to the core with the flammable coating.

[0014] The beneficial effects of this utility model are as follows:

[0015] Unlike existing technologies, in actual use, the copper-plated heads at both ends of the flux core facilitate stable current transmission and improve welding stability. Multiple flux cores are arranged in a ring array, with one of the flux cores containing a combustion-supporting agent. This allows one flux core to assist the others in combustion, enabling the flux cores to ignite quickly. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 - Figure 3 As shown, a flammable underwater welding and cutting electrode includes multiple flux cores 1 and a wrapping element 2 sleeved on the flux cores 1, and also includes:

[0023] Copper-plated heads 5 are located at both ends of the core 1;

[0024] Flammable coating 3 is disposed at the end of one of the cores 1.

[0025] The flux cores 1 are arranged in a ring array, and multiple flux cores 1 form oxygen outlet holes 4, which can work with the oxygen sprayed from the welding torch to form bubbles at the end, effectively isolating the electric arc and providing a stable working environment for the underwater welding and cutting process.

[0026] The package 2 includes a polytetrafluoroethylene (PTFE) tube 21, a metal layer 22, and a waterproof layer 23. The PTFE tube 21, metal layer 22, and waterproof layer 23 are sequentially fitted onto the core 1 from the inside out. The PTFE tube 21 has good insulation properties and can withstand certain high temperatures to prevent it from melting prematurely before it is ignited. The PTFE tube 21 can also isolate the current in the middle section of the core 1 to prevent accidental ignition. The metal layer 22 is responsible for current conduction, and the waterproof layer 23 ensures waterproofing. The multi-layer structure together provides comprehensive protection for the core.

[0027] The copper-plated heads 5 have different lengths, with the longer copper-plated heads 5 connected to the welding gun. Copper has excellent electrical conductivity, thereby enabling rapid ignition and stable combustion of the flux core 1.

[0028] The longer copper-plated head 5 has a hollow end, and this hollow section is placed in the welding torch to prevent the flux core 1 from burning into the welding torch.

[0029] Adding a combustion-supporting agent to the flux core 1 with a flammable coating 3 can help ignite the flux core, so that the welding and cutting bar can be quickly ignited when the current is conducted to this end, thereby starting the underwater welding and cutting operation.

[0030] It should be noted that when this flammable underwater welding and cutting electrode is in operation, the welding torch is first started, and the current is conducted through the copper-plated head 5 at one end of the flux core 1 to the copper-plated head 5 at the other end. The current in the middle section of the flux core 1 is isolated by the PTFE tube 21 to prevent accidental ignition in the middle section of the flux core 1. When the current reaches the other end of the flux core 1, it is ignited by the flammable coating 3. When the flammable coating 3 is ignited, a flame is generated. Throughout the process, the oxygen sprayed from the welding torch forms bubbles at the end of the oxygen outlet 4, which isolate the electric arc and allow the flux core 1 to burn, thereby achieving underwater welding and cutting.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
