Description
Technical Field
The invention belongs to the technical field of welding, and particularly relates to an all-position consumable electrode arc-laser double-sided composite welding process and equipment thereof.
Background
With the development of energy industry and the adjustment of energy structure in China, the construction of pipeline engineering is also developed rapidly, and the problem of the construction quality of pipeline engineering brought by the development is also the focus of attention of people. The all-position welding of the pipeline is a key link in the field construction of the pipeline, and is directly related to the quality, the construction efficiency and the cost of the project. At present, manual electric arc welding, flux-cored wire semi-automatic electric arc welding and Gas Metal Arc Welding (GMAW) in China are well applied, particularly GMAW plays an important role in pipeline construction, but the defects are that a plurality of welding guns and a plurality of layers of welding beads are needed for completing one joint.
The main advantages of laser welding over conventional arc welding are that the laser deep fusion welding mode can obtain a weld with a large depth-to-width ratio, a large penetration at one time, and a small number of required weld passes, thereby greatly reducing welding deformation. Therefore, the laser welding replaces the traditional welding method (mainly manual arc welding and gas metal arc welding) used in the current pipeline welding, so that the single-pass welding without beveling or the great reduction of the number of welding layers becomes possible, the welding speed and the welding production efficiency are greatly improved, and more importantly, the welding deformation can be reduced. Meanwhile, the energy density of a welding heat source is concentrated, the linear energy is small, and the HAZ is narrow, so that the mechanical property of a welding joint is excellent. However, due to the defects of complex laser welding process, high equipment cost, high requirement on workpiece assembly precision and the like, the laser welding method is difficult to popularize and apply in a large range.
The laser-electric arc composite heat source welding technology is firstly proposed by a scholars W.Steen in the end of the 70 th 20 th century, and the main idea is to effectively utilize laser energy, realize larger welding penetration under the condition of smaller laser power, improve the adaptability of laser welding to a welding seam gap and realize a high-efficiency and high-quality welding process. At present, the laser-arc hybrid welding technology has been successfully used in the fields of shipbuilding, automobiles, storage container manufacturing and pipeline welding, and has the advantages of improving the welding speed, increasing the section thickness of weldable materials, reducing equipment and welding deformation, and improving the welding appearance under the critical fatigue working condition. However, laser-arc hybrid welding also has some problems: 1) the laser beam can reach the surface of the workpiece only after passing through the arc column, and the laser energy is seriously lost when the arc current is large; 2) the electrode is directly exposed in laser plasma and is easy to be polluted and seriously burnt; 3) when the paraxial is compounded, the electric arc and the laser beam form a certain angle to cause the action area of the compound heat source on the workpiece to be in asymmetric distribution, and when the current is increased to a certain degree, the action points of the laser and the electric arc are seriously separated.
