Background
The welding technology dates back to the bronze times thousands of years ago, and the rudiment of the welding technology can be seen in the early industrial civilizations of human beings, both domestically and internationally. Welding is a method of joining metals by the technique of permanently joining the two metals together by applying heat, pressure or other means to form a new material combination at the point of contact between the two metals.
Welding techniques have emerged with the use of metals, and the ancient welding methods have primarily been cast, brazed, and forge welded. The welding technology is mainly applied to metal base materials. At present, arc welding, argon arc welding, CO2 shielded welding, oxygen-acetylene welding, laser welding, electroslag pressure welding and the like are commonly used.
Welding is a local rapid heating and cooling process, and due to different workpiece materials, welding current and the like, overheating, embrittlement, hardening or softening phenomena can occur in a welding seam and a heat affected zone after welding, so that the quality of a welded part is also reduced.
In general, since the weld zone is free to expand and contract without being constrained by the workpiece body, weld stress and deformation occur in the weldment after cooling. Thereby limiting the range of applications for welding techniques. It will increase the cost of subsequent processing for products with higher precision requirements (e.g., hole site size).
In welding processing, a welding positioning tool is usually adopted, a to-be-welded part is positioned by means of a positioning device, other means are not needed, and an accurate assembly position can be obtained even if measurement is not needed, so that the welding precision is ensured, and the process of welding operation is accelerated. However, the spatial (three-dimensional) special-shaped piece means that the upper surface and the lower surface of the workpiece are not in the same or similar patterns, and the positions to be welded are not regular lines or surfaces.
Therefore, for the welding of the spatial special-shaped piece, the positioning cannot be accurately performed, which not only affects the welding quality, but also cannot ensure the precision after welding forming.
