Problems solved by technology

Among them, gas shielded welding has a very wide range of applications. Gas shielded welding uses gas as the arc medium and protects the arc and welding area. However, gas shielded welding is very sensitive to the external environment, because the shielding gas is easily disturbed by the external environment, which in turn affects the protection effect and finally affects the weld quality

Embodiment Construction

[0025] combine Figure 1-6 , Shown in 8, this patent is described further.

[0026] The present invention is a technical improvement made in the prior art. In the prior art, the welding head includes a shielding gas delivery port for conveying the shielding gas, and a welding wire drum 5 that continuously feeds welding wire 10, and the welding wire 10 is at the bottom of the welding wire drum 5 The end is ignited to generate a welding heat flame 11, and the base metal 12 is welded together; in the prior art, the shielding gas delivery port is set outside the welding wire cylinder 5, so that the shielding gas can protect the welding part of the welding wire 10.

[0027] The welding head provided by the application is provided with a gas cylinder 3 in the prior art, and the gas cylinder mouth is provided between the gas delivery port and the bottom end of the welding wire cylinder 5; there are at least two gas cylinders 3, which are respectively an air supply cylinder and an air...

Abstract

The invention discloses a three-dimensional surrounding gas shielded welding welding-head, and belongs to the field of welding devices. According to the three-dimensional surrounding gas shielded welding welding-head, a control circuit-temperature difference path is formed between hot guide wheels and low-temperature guide wheels which automatically draw high heat from initial weld seams of a basemetal through the airflow of four air cylinders. Electric energy supplied by a motor is spontaneously generated through thermoelectric effect, rotation of alternately arranged suction fans and blowing fans is controlled, and finally the three-dimensional surrounding and continuously circulating protective airflow is formed at a certain distance from the periphery of the welding thermal flame. Onthe one hand, the external impurity gas can be prevented from being mixed in, wherein nitrogen-doped and oxygen-doped impurities can be generated in the weld seams, so that the quality of the weld seams is affected; and on the other hand, the influence of the external environment, such as crosswind, on the welding thermal flame is weaken.

Description

technical field [0001] The invention belongs to the field of welding devices, and in particular relates to a three-dimensional surrounding gas shielded welding joint. Background technique [0002] There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Among them, gas shielded welding has a wide range of applications. Gas shielded welding uses gas as the arc medium and protects the arc and welding area. However, gas shielded welding is very sensitive to the external environment, because the shielding gas is easily disturbed by the external environment, which affects the protection effect and finally affects the quality of the weld. Contents of the invention [0003] In view of the above deficiencies, the device of the present invention provides a three-dimensional surrounding gas shielded welding joint, which aims to set a gas cylinder inside the shielding gas in the gas shielded welding t...
