Embodiment

[0025] Example: such as Figure 1-4 Shown, a kind of H-beam robot submerged arc welding method comprises the following steps:

[0026] The first step: the assembled pre-welded H-shaped steel 7 is placed on the bidirectional turning assembly 6 by the RGV conveying trolley. When the main weld of the pre-welded H-shaped steel 7 is a groove weld, the bidirectional turning assembly 6 will pre-weld the H-shaped steel 7 Flip 45°. When the main weld seam of the pre-welded H-shaped steel 7 is non-groove welding, the pre-welded H-shaped steel 7 is placed flat on the bidirectional turning assembly 6 .

[0027] Step 2: After placing the pre-welded H-beam 7, the traveling gantry 2 moves along the traversing track 1 to the side of the pre-welded H-beam 7, and then welds the welder cross arm 4 on the extension platform 3 to drive the submerged arc welding robot 5 To the top of the pre-welded H-shaped steel 7.

[0028] Step 3: After completing the operation preparation process of the subme...

Abstract

The invention relates to an H-shaped steel robot submerged arc welding method, and belongs to the technical field of structural steel welding. The H-shaped steel robot submerged arc welding method comprises the following operation steps that firstly, assembled pre-welded H-shaped steel is placed on a both-way overturning assembly through an RGV conveying trolley; secondly, after the pre-welded H-shaped steel is placed, a submerged arc welding robot conducts the running preparing process; thirdly, the submerged arc welding robot conducts positioning welding work; fourthly, after upper-end-facewelding work is finished, the submerged arc welding robot resets to the original position, then, the both-way overturning assembly runs and conducts 180-degree overturning on the pre-welded H-shaped steel; and fifthly, the submerged arc welding robot continuously conducts the submerged arc welding process on two welding lines on the other end face of the pre-welded H-shaped steel, and after all welding is finished, the RGV conveying trolley is used for conducting material taking and replacing. The characteristics that running stability is good, time and labor are saved, the welding efficiencyis high, and the usage effect is good are achieved. The structural steel deformation phenomenon caused by hoisting and overturning is reduced, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of section steel welding, in particular to a robotic submerged arc welding method for H-section steel. Background technique [0002] Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method in which the arc burns under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacturing, and box-shaped beams and columns. In recent years, although many new welding methods with high efficiency and high quality have appeared successively, the application field of submerged arc welding has not been affected in any way. Especially in the production of wind tower tubes, in order to ensure production efficiency, automatic submerged arc welding is mostly used for the l...
