High frequency electric welded steel pipe welding fusion area and V-type corner imaging monitoring device

Abstract

The invention relates to a high frequency electric welded steel pipe welding fusion area and V-type corner imaging monitoring device. An upper squeeze roller installation base is fixed on the side wall of a main rack and is provided with two upper squeeze rollers, two side squeeze rollers are arranged below the upper squeeze rollers, a fixed board is installed on the main rack, a camera is fixed on the lower surface of the fixed board, the camera is connected with a computer and a display screen through a transmission cable, a filter lens is fixed on the camera, and the camera aligns at the center positions of the two upper squeeze rollers and aligns at the center positions of the two side squeeze rollers at the same time. By means of the device, a high frequency electric welded steel pipe operator can visually observe the welding area in real time, parameters such as length and opening angle, not capable of being easily measured, of the welding fusion area are digitalized, and the welding state is observed by the operator more visually and is changed to be the digital parameters.

Description

technical field [0001] The invention relates to a high-frequency electric welding steel pipe welding fusion zone and V-shaped angle imaging monitoring device, and the invention belongs to the technical field of steel pipe manufacturing and processing devices. Background technique [0002] High-frequency electric welded steel pipes are widely used in the fields of petroleum and natural gas exploration and transportation, auto parts manufacturing, refrigerator manufacturing and machinery equipment manufacturing, and due to the cost advantage of high-frequency welded pipes, many fields using seamless steel pipes have begun Steering is replaced by high frequency electric welded steel pipe. With the continuous increase of the application range, the quality requirements for high-frequency electric welded steel pipes are getting higher and higher. At present, the welding quality of high-frequency welded steel pipes mainly depends on observing the shape of the burr after welding, t...

AI Technical Summary

Problems solved by technology

At present, the welding quality of high-frequency welded steel pipes mainly depends on observing the shape of the burr after welding, the degree of spark spatter after welding, and the parameters of forming and welding processes to ensure the welding quality. It cannot be observed very intuitively. In this case, the same forming And the welding process, the same welding state observed, when producing steel pipes of different steel materials, due to the difference in raw material properties, it is difficult to produce high-quality welded pipes with stable quality
