Description
Technical Field
The application relates to the technical field of welding equipment, in particular to a protection assembly and a flash butt welding machine.
Background
The flash butt welding machine has two types of continuous flash butt welding and preheating flash butt welding. The former has been welded to have only a flash butt and upset stage, the latter having a preheating stage between successive flash butt welds. The flash butt welding mainly utilizes the heat generated by the butt contact resistance of the workpiece to heat the workpiece, the metal surface is melted, the temperature gradient is large, and the heat affected zone is small. The welding seam is formed into common crystal grains under the condition that the workpiece opposite solid phase metal generates plastic denaturation. The weld structure and the components are close to those of basic metal (or are subjected to heat treatment), and equal-strength plastic welded joints are relatively easy to obtain. The flash process has the self-protection function of exhausting air and reducing metal oxidation. Upset forging also displaces oxides with the liquid metal out of the weld. The defects of inclusion, incomplete penetration and the like of the welding line are less. The flash process has a strong self-adjusting function, the requirement on strict keeping of standard consistency is low, and the welding quality is stable. The unit welding cross section area needs small electric power, and the welding of the low-carbon steel only needs (0.1-0.3) KVA/mm2 electric power. The welding productivity is high, and only a few seconds to a few tens of seconds are needed for welding one joint. The welding has wide application range, and metal materials which can be forged can be welded by flash butt welding in principle. Non-ferrous metals and alloys such as low carbon steel, high carbon steel, alloy steel, stainless steel, etc. can be flash butt welded. The welding cross section area is wide, and the welding cross section area can be generally welded from dozens of mm to tens of thousands of mm 2. Flash butt welding is widely applied to welding various plates, pipe fittings, sectional materials, solid parts, cutters and the like, is very widely applied, and is an economic and efficient welding method.
The existing high-precision flash butt welding machine can generate sparks along with the generation of sparks in the welding process, and the generated spark flying chips can have certain potential safety hazards.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Flash butt welding is widely used for longitudinal connection of reinforcing steel bars and welding of prestressed reinforcing steel bars and screw end rods. The principle of flash butt welding of steel bars is to use a butt welding machine to make the steel bars at two ends contact, and after the steel bars are heated to a certain temperature and become soft by a low-voltage strong current, axial pressure upsetting is carried out to form a butt welding joint. The steel bar flash butt welding process commonly uses continuous flash welding, preheating flash welding and flash-preheating-flash welding. The IV-grade steel bars are also subjected to electric current heat treatment after welding.
The flash butt welding mainly utilizes the heat generated by the butt contact resistance of the workpiece to heat the workpiece, the metal surface is melted, the temperature gradient is large, and the heat affected zone is small. The welding seam is formed into common crystal grains under the condition that the workpiece opposite solid phase metal generates plastic denaturation. The weld structure and the components are close to those of basic metal (or are subjected to heat treatment), and equal-strength plastic welded joints are relatively easy to obtain. The flash process has the self-protection function of exhausting air and reducing metal oxidation. Upset forging also displaces oxides with the liquid metal out of the weld. The defects of inclusion, incomplete penetration and the like of the welding line are less. The flash process has a strong self-adjusting function, the requirement on strict keeping of standard consistency is low, and the welding quality is stable.
The unit welding cross section area needs small electric power, and the welding of the low-carbon steel only needs (0.1-0.3) KVA/mm2 electric power. The welding productivity is high, and only a few seconds to a few tens of seconds are needed for welding one joint. The welding has wide application range, and metal materials which can be forged can be welded by flash butt welding in principle. Non-ferrous metals and alloys such as low carbon steel, high carbon steel, alloy steel, stainless steel, etc. can be flash butt welded. The welding cross section area is wide, and the welding cross section area can be generally welded from dozens of mm to tens of thousands of mm 2. Flash butt welding is widely applied to welding various plates, pipe fittings, sectional materials, solid parts, cutters and the like, is very widely applied, and is an economic and efficient welding method.
