Orbital Weld Head Clearance: Completing High Spec Welds in Small Spaces

AMI’s orbital welding solution for nuclear application

In industrial settings, components including pipes in refineries and factories or tubes in heat exchangers and industrial condensers are often aligned in a very close sequence. The integrity and strength of these components play a crucial role in operational performance. So, any construction and repair work needs to be highly specified and based on industrial standards. However, given the confined configuration of these components, welding for these applications can be difficult.

Ensuring ideal high specification welding operation in such spaces requires a technology that can operate and produce high-quality, low-clearance welds. Optimal outcomes can be difficult to achieve with manual welding. Low orbital weld head clearance capabilities, however, enable welders to perform consistent and reliable welds in confined areas while ensuring maximum welding safety.

Welding Operation in Applications With Low Clearance Requirement

Many welding sites require welders to work on components with difficult geometries or navigate spaces that do not allow easy movement. The following challenges arise when attempting to perform high-quality welds in tight spaces with conventional manual welding:

  • Inability to reach all corners while welding.
  • Inability to weld different kinds of geometries.
  • High exposure to welding fumes.
  • High risk of error from fatigue as a result of welding in uncomfortable positions.

To minimize these welding risks and errors, manufacturers can employ an automated welding technology that can operate in tight spaces without posing ergonomic or safety risks to welders and operators.

Automated Welding Ensures Quality and Minimizes Risks

In confined and hard-to-reach workspaces, an automated system like orbital welding offers an ideal solution. An orbital weld head that fits into the available clearance enables the automated system to provide the following advantages:

  • Remote monitoring ensures welders and operators stay safe from any hazardous weld fume exposure, and the weld is not exposed to any error resulting from human fatigue.
  • The automated system allows the weld head to reach the angles and spaces where manual welding is difficult to achieve.
  • Optimizable parameters in the automated system ensure the weld is consistent and up to the standards required for high-specification welding.
  • Consistent, high-quality welds help ensure component strength and reduce the chances for inclusions, cracks, or lack of fusion. 

An ideal solution required for industries with high specification welding requirements is the provision of orbital weld head clearance to achieve high-quality and precision welding.
