Description

Welding tool for steel pipe and flange

Technical Field

Background

In the fields of gas transportation and liquid transportation, steel pipes are required to be used as transportation members, flanges are generally welded to both ends of each steel pipe to meet the requirement of connection between multiple sections of steel pipes, and then the flanges are used to connect adjacent steel pipes. The cross section size of the steel pipe is set according to the requirement, and in addition, the cross section of the steel pipe is generally circular, but in the field of partial conveying, the cross section of the steel pipe is set according to the actual application scene, for example, when the steel pipe is used as a flue to convey gas, the cross section of the steel pipe is generally rectangular.

The inventor knows that a welding positioning tool for the flange and the steel pipe exists in the related technical scheme, and the tool can respectively clamp or support and position the steel pipe and the flange; specifically, the steel pipe is rotated to enable the end to be welded to face the direction of the flange, then the flange is moved to enable the flange to be positioned with the corresponding end of the steel pipe to be welded in a preset mode, and further subsequent welding is completed. The scheme is convenient for enabling all ports of the Y-shaped or cross-shaped steel pipes to be welded with flanges respectively through rotation.

However, the inventor considers that the supporting structure of the steel pipe in the scheme is inconvenient to adapt to steel pipes with different section sizes or shapes; for example, when a V-groove is used to position a round steel pipe with a non-preset size, the height between the central axis of the supported round steel pipe and the positioned flange axis is different due to the different diameters of the round steel pipe, so that the welding cannot be performed.

For another example, when a semicircular positioning groove is used to position a circular steel pipe, the semicircular positioning groove is inconvenient for supporting and positioning a steel pipe having a rectangular cross section.
