Problems solved by technology

In the spiral welded pipe production line, any traditional welding method such as fusion welding, resistance welding, gas welding, vacuum diffusion welding, etc. cannot meet the needs of welding different grades of aluminum alloys.
For large-diameter steel spiral welded pipes, submerged arc automatic welding is generally used at home and abroad. After decades of gradual improvement, this technology has matured and can produce high-quality spiral welded pipes, but submerged arc automatic welding is not suitable for aluminum alloy spiral pipes. Welding, in addition, the double-sided plasma welding of aluminum alloy spiral tube is rarely used in China

Embodiment Construction

[0009] Such as figure 1 , 2 As shown, the aluminum alloy spiral pipe welding machine is equipped with a spiral pipe blank rolling device 1, two sets of rotating rollers 2, 4, a TIG welding torch 3, a first plasma welding torch 7, a second plasma welding torch 8, and a robot on the frame. Automatic punching machine 9, image acquisition system 6 and welding parameter acquisition system 5.

[0010] Each welding torch is a robotic automatic welding torch. The TIG welding torch 3 is set at the six o'clock position of the frame, which is flat welding. The first plasma welding torch 7 and the second plasma welding torch 8 are both set at the twelve o'clock position of the frame. The plasma torch 7 is for flat welding, the second plasma torch 8 is for overhead welding, and two groups of rotating rollers 2, 4 are respectively arranged at three o'clock and nine o'clock positions of the frame. The robot automatic punching machine 9 positions can be adjusted, and it is set at the one o'...

Abstract

A quality evaluating system for the welding parameter of an aluminum alloy spiral pipe belongs to the technical field of automatic welding. The quality evaluating system comprises a Hall current sensor and a Hall voltage sensor which are separately connected to a welding power supply, wherein the data output ends of the Hall current sensor and the Hall voltage sensor are connected to a computer control center through data acquisition cards. The quality evaluating system further comprises an industrial CCD video camera arranged corresponding to a welding seam, the data output end of the industrial CCD video camera is connected to the computer control center through an image acquisition card, and an output end of the computer control center is connected with a punching motor through a punch driving circuit. The work of the punching motor is driven through the punch driving circuit so as to realize intelligent positioning and automatic punching and help a welding robot subsequently follow and rapidly and specifically repair a welding seam region in which marks are made.

Description

technical field [0001] The invention belongs to the technical field of automatic welding, in particular to the quality evaluation of welding parameters of aluminum alloy spiral pipes. Background technique [0002] The aluminum alloy spiral tube is made by rolling the aluminum alloy coil into a spiral tube billet according to a certain helical angle, and then welding the tube seam. In the spiral welded pipe production line, any traditional welding method such as fusion welding, resistance welding, gas welding, vacuum diffusion welding, etc. cannot meet the needs of welding different grades of aluminum alloys. For large-diameter steel spiral welded pipes, submerged arc automatic welding is generally used at home and abroad. After decades of gradual improvement, this technology has matured and can produce high-quality spiral welded pipes, but submerged arc automatic welding is not suitable for aluminum alloy spiral pipes. Welding, in addition, the double-sided plasma welding o...
