Description

Metal pipeline installation field welding equipment Technical Field The invention relates to the technical field of welding. More particularly, the present invention relates to a metal pipe installation field welding apparatus. Background In the process of installing metal pipes, it is often necessary to weld the annular gap between two adjacent sections of pipe. The gap is in a circular ring shape, and the welding gun is required to accurately perform complete circular motion along the gap during welding so as to ensure that the welding seam continuously and uniformly covers the whole joint area, and synchronously perform reciprocating swing in the left-right direction while circumferentially travelling. The composite movement can effectively control the width and shape of the molten pool, so that the weld joint is formed more fully, neatly and attractive. However, the operation has extremely high technical requirements on manual welding, namely an operator has to coordinate the rotation track and the transverse swing rhythm of the arm at the same time, so that the welding gun is kept to be aligned with the narrow gap center precisely all the time, stable welding speed and angle are maintained, the operation difficulty is high, and the experience and the proficiency of a welder are extremely high. Disclosure of Invention In order to overcome the defects that when the existing welding gun is used for welding two sections of adjacent pipelines, an operator needs to coordinate the rotation track and the transverse swing rhythm of an arm at the same time, the welding gun is required to be kept to be aligned with a narrow gap center all the time accurately, stable welding speed and angle are required to be maintained, and the operation difficulty is high, the invention provides a metal pipeline installation field welding device.
