Copying welding device free of blind area and copying welding method free of blind area

Abstract

The invention provides a copying welding device free of a blind area. The copying welding device free of the blind area comprises a welding gun copying adjusting frame. A welding gun is arranged on the welding gun copying adjusting frame. The welding gun copying adjusting frame enables the welding gun to swing. The invention further provides a copying welding method free of the blind area. The copying welding method free of the blind area comprises the step of welding a curved-weld-joint through the welding gun. One motor is used for driving the welding gun to swing, and copying welding of theweld joint in any shape is conducted through the welding gun by the adoption of an elastic device; the turning tendency of a magnetic base can achieve copying on a weld joint of a workpiece in a gapless manner; welding can be conducted on a non-horizontal weld joint through the magnetic force, generated by a magnet on the magnetic base, acting on the base plate of the workpiece; if obstacles exist on the two sides of the weld joint in the length direction, welding can be stilled conducted at the starting position and ending position of the weld joint, manual follow-up repairing welding is notneeded, the appearance is consistent, and the attractiveness is high; copying welding of different weld joints can be achieved, operation is easy, and the functional cost is low.

Description

Technical field [0001] The invention relates to a profiling non-blind-zone welding device and a welding method thereof, and belongs to the technical field of non-blind-zone automatic welding of welds such as straight lines, arcs, and special shapes. Background technique [0002] The welding trolley (gas shielded welding) can automatically weld straight and arc welds. The welding torch is fixed on the welding trolley. There are four wheels on the lower part of the welding trolley. The different sizes of the wheels make the welding trolley always keep turning in one direction. , In this direction, there are two supporting wheels on the side of the trolley, which can resist the vertical plate and other objects to realize the profiling walking without gaps, thereby driving the movement of the welding gun, and then realizing welding. However, because the welding carriage itself has a certain width, if there are obstacles on both sides of the weld length direction, welding cannot be ca...

AI Technical Summary

Problems solved by technology

However, since the welding trolley itself has a certain width, if there are obstacles on both sides of the weld seam length direction, welding cannot be performed at the beginning and end of the weld seam, and manual subsequent repair welding is required. The appearance is different, affecting the aesthetics

[0003] At present, the existing non-blind zone welding trolley is usually driven by two motors, and the linear swing of the welding torch head is realized through intelligent control. For arc welds, the welding speed and welding distance must be guaranteed, and the different arcs need to correspond to the speed of the two motors. Different products have a variety of forms, and there may be different combinations of radians. Therefore, it is extremely complicated to realize the profiling welding of different welds in this way, and the cost of realizing the function is high.

[0004] In view of the above problems that the current welding trolley can not realize the full-length welding of the weld and the existing non-blind zone welding trolley realizes the complex and costly method of no blind zone, this profiling non-blind zone welding device is specially designed
