AI Technical Summary

Problems solved by technology

The clamping mechanism of a clip-on weld head can significantly affect the accuracy of said weld
For example, an unstable or misaligned attachment of the welding head to the pipe by the clamping mechanism can result in imprecise welds which can subsequently lead to premature fatigue, damage or breakage

Embodiment Construction

[0017] The examples are provided to illustrate various techniques, systems and devices for welding systems using a welding head including an adjustable clamping mechanism with a quick release insert.

[0018] In one aspect, the disclosed technology can include an adjustable clamping mechanism for a welding head in a welding system, such as an orbital welding system, where the welding head travels around a welding workpiece. An adjustable clamping mechanism may be implemented to secure the welding head in place on a welding workpiece (eg, a pipe, pipe body, or other type of welding workpiece). Exemplary welding heads may include hand-held or other portable welding heads.

Abstract

Techniques, systems, and devices are described for a weld head that includes an adjustable clamping mechanism with a quick release insert. In one aspect, a weld head having an adjustable clamping mechanism for clamping a welding work piece includes a weld head containment structure having an opening that receives a welding work piece, a clamping member located inside the opening of the weld head containment structure and including a pivot joint for clamping the welding work piece to the weld head, a handle member connected to the clamping member at the pivot joint to rotate the clamping member when the handle member is moved, and an actuator coupled to the clamping member to enable the clamping member to pivot on the pivot joint to different clamping positions for clamping welding work pieces of different sizes.

Description

Background technique [0001] This patent document relates to welding systems, apparatus and methods. [0002] Welding in large industrial applications such as metal inert gas (MIG) and tungsten inert gas (TIG) tube or plate welding involves joining thick workpieces together in an orbital welding process. In orbital welding, the welding head can be mounted to the workpiece and driven by a motor to continuously rotate 360 ​​degrees around the workpiece (such as a pipe), or rotate 180 degrees around the pipe on one side of the pipe and then repeat the head on the other side of the pipe rotate. From small standard workpieces to larger gauge workpieces, many welding applications require precision welding. Orbital welding processes can be mechanized and automated, which has advantages over manual welding processes including consistent weld repeatability, improved weld quality, reduced operator fatigue, higher production output and lower Scrap rates and reduced complexity of weldin...
