Description

Technical field [0001] The present application relates to the technical field of welding equipment, and more particularly to a welding device. Background technique [0002] The welder is a high-temperature electric arc generated by a positive and negative bipolar during an instant to melt the solder and solder material, which combines the contact object, which is very simple, which is a high-power transformer, electric welder. It can generally be divided into two kinds in output power supply, one is an AC power source, one is direct current. They use the principle of inductance, the inductance will generate huge voltage changes when turning on and disconnect, using the high voltage arc generated by the positive and negative biplings to melt the solder on the electrical bonders to reach atomic binding. And the existing electric welding machine has a certain drawback in use, which is prone to a large number of solder slags. There is no reliable protective device to handle the solde...

AI Technical Summary

Problems solved by technology

They use the principle of inductance, the inductance will produce a huge voltage change when it is turned on and off, and use the high-voltage arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder on the welding rod, so that they can achieve the purpose of atomic bonding ; while the existing electric welding machine has certain disadvantages in use, it is easy to produce a large amount of welding slag, and there is no reliable protective device to process the welding slag, which has brought certain influence in use. For this reason, we propose a Protective device for welding slag splashing of electric welding machine

[0003] During the droplet transition, the CO gas produced by the reaction of FeO and C in the droplet expands rapidly under the high temperature of the arc, causing splashing caused by the explosion of the droplet. The cooling effect is strong, which increases the electric field intensity of the arc, shrinks the arc, reduces the area of ​​the arc root, and increases the spot pressure of the arc. The droplet is very unstable under the spot pressure and forms spatter, which increases the impurities in the welding point and affects the welding point. The connection between the various material structures, the appearance of spatter greatly limits the quality of the overall welding
