Description

Technical Field

[0001] The present invention relates to the technical field of submerged arc welding, and in particular to intelligent welding equipment for steel processing. Background Art

[0002] Automatic or semi-automatic arc welding is a welding method that uses an electric arc as a heat source to melt the base material and filler material (welding wire). This welding method is usually operated with automated or semi-automated equipment to improve welding efficiency and quality.

[0003] Among them, automatic arc welding is a fully automated welding method, which is usually used for continuous welding of long straight welds.

[0004] Semi-automatic arc welding is a welding method between manual and fully automatic. It usually requires manual operation of the welding gun, but the movement of the welding gun can be assisted by a mechanical device.

[0005] Common automatic or semi-automatic arc welding methods include:

[0006] Submerged arc welding: uses flux to cover the arc and is suitable for welding thick plates.

[0007] Gas shielded welding: uses inert gas to protect the molten pool and is suitable for welding a variety of materials.

[0008] Tungsten inert gas welding: uses non-melting tungsten electrode and argon gas protection, suitable for precision welding.

[0009] Flux-cored arc welding: uses a flux-cored wire containing flux and is suitable for outdoor and indoor welding.

[0010] Among them, submerged arc welding (including submerged arc cladding and electroslag cladding) is a welding method in which the arc burns under the flux layer. It has the advantages of stable welding quality, high welding productivity, no arc light and less smoke. It has become the main welding method in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beams and columns.

[0011] In the prior art, the submerged arc welding of steel structure tubular parts is relatively complicated, requiring auxiliary personnel to keep the two steel structure tubular parts to be welded coaxially aligned, and during welding, the welder operating the welding head must also cooperate to synchronously rotate the two steel structure tubular parts to be welded, which is time-consuming and labor-intensive and has low welding efficiency.
