Description

Technical Field

[0001] The present application relates to the technical field of gas shielded welding, and in particular to a gas shielded welding device. Background Art

[0002] Gas shielded welding is a welding technology widely used in machinery, construction, automobile and other industries. Gas shielded welding refers to a welding method protected by carbon dioxide or argon gas. Welding wire is used instead of welding rods. Carbon dioxide welding has high efficiency. Argon shielded welding is mainly used to weld aluminum, titanium, stainless steel and other materials. Submerged arc welding uses welding wire and flux protection. The flux buries the arc like sand and is mainly used for welding thick plates.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the gas shielded welding machines in traditional technologies are generally not equipped with equipment to fix the workpiece. Therefore, when welding the workpiece, it is easy for the workpiece to shift, thereby affecting the welding effect. At the same time, impurities such as sparks and debris will be generated during welding. These impurities will diffuse into the air. If they are absorbed by the welder, they will have an adverse effect on the welder's health. There are defects. Therefore, a gas shielded welding device is proposed to solve the above problems.
