Description

Technical Field

[0002] The melon-segment spherical head is a special pipe connector. It is a spherical head made up of several triangles or trapezoids. It has good fluid mechanics properties and beautiful appearance. When welding the melon-segment spherical head, first weld the butt welds between the top round plate and each petal, and then weld the butt welds between the petals. The welding between the petals should be carried out from bottom to top, and the welding should be performed symmetrically.

[0003] However, the existing melon-segment spherical heads need to be welded manually. The staff first needs to splice several melon-segment spherical heads and use a ladder to weld along the arc from the top of the melon-segment spherical heads. This welding method requires the welders to wear personal protective equipment, which is inconvenient to operate. At the same time, the existing melon-segment spherical heads need to be welded symmetrically, which increases the labor cost. In addition, the existing melon-segment spherical heads need to ensure that the butt welds of each petal are flat when assembling, which makes welding difficult. Summary of the invention
