The invention provides a pipe fitting centering cutting device and method, relates to the technical field of pipe fitting machining, and aims to solve the problems that the machining precision is poor and the service life of a cutter is affected due to the fact that the feeding amount control precision is poor when an insertion opening of a pipe fitting is cut at present. The two limiting wheels arranged on the limiting support in a spaced mode abut against the cylindrical mold at the same time, the centering effect of the abutting position is achieved, the cutting position of the cutting tool is kept to be located on the perpendicular bisector of the connecting line of the two limiting wheels, and the retraction distance of the limiting support is made to be consistent with the cutting depth of the cutting tool; and the control precision is improved to improve the durability and stability of the equipment.

The invention provides a chemical storage tank outer wall welding device and method, and belongs to the technical field of storage tank machining equipment. At present, a molten pool formed during cylinder welding is influenced by fluctuation during cylinder rotation, fluctuation of fusion width and fusion depth can be generated, welding seam forming is not uniform, and welding quality and strength are influenced. The bearing assembly and the welding assembly are configured to perform combined welding on the barrel, the bearing assembly can support the barrel to be subjected to combined welding and can drive the barrel to synchronously rotate, and the welding assembly welds the butt joint position of the barrel in an inclined state, so that the state of a molten pool is stable, and fluctuation of the fusion depth and the fusion width is reduced; and the welding seam forming uniformity is improved to ensure the welding quality.
