Remote Vessel Welding Head Positioning for Confined Interior Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding interior surfaces of vessels, such as pressure vessels, is challenging due to limited access, high temperatures, poor visibility, and hazardous conditions, making it difficult for traditional welding devices to maneuver and operate safely within confined spaces.
Innovation Solution
A remote welding apparatus with a support, base member, and rotatable arm that fits within a vessel opening, equipped with a welding head and computing device for improved access and visibility, allowing for remote control and visualization of the welding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional welding devices are used to weld interior surfaces of vessels, then welding operations can be performed, but access and maneuverability are severely limited due to confined spaces and hazardous conditions
Solution Approach 1:
The patent introduces a remote-operated welding apparatus that acts as an intermediary between the operator and the hazardous welding environment. The apparatus includes a support structure with a base member and arm that can be positioned through vessel openings, allowing welding operations to be performed from a remote, safe location while the welding head operates within the confined interior space
Solution Approach 2:
The patent replaces traditional manual welding operations with an automated or remotely-controlled welding system. The welding head is equipped with welding power supply connections and can be precisely positioned and manipulated through the arm mechanism, eliminating the need for welders to physically enter hazardous environments
2Adaptability or versatility
If the arm is made rotatable to improve maneuverability within the vessel, then access to different interior surfaces is enhanced, but the device complexity increases
Solution Approach 1:
The patent divides the support structure into separable components: a base member and an arm that are rotatably coupled. This segmentation allows the arm to rotate independently relative to the base member, enabling the welding head to reach various interior surfaces of the vessel while maintaining a relatively simple overall structure
Solution Approach 2:
The patent introduces rotational movement capability to the arm relative to the base member, transforming the structure from static to dynamic. This allows the welding apparatus to adapt its positioning and orientation as needed during welding operations, enhancing versatility without requiring multiple separate devices
3Loss of information
If a computing device is added to capture images for remote visualization, then visibility and monitoring are improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses imaging devices (such as cameras) mounted on or near the welding head to capture visual copies of the welding interface and interior vessel surfaces. These images are transmitted to remote locations, allowing operators to monitor welding operations and assess conditions without being physically present in the hazardous environment
Solution Approach 2:
The computing device and imaging system serve as intermediaries that bridge the gap between the remote operator and the welding environment. By capturing and transmitting visual information, the system allows operators to maintain situational awareness and control welding operations from a safe distance

AI summary
An apparatus can include a support, and a base member coupled with the support at a first end of the base member, the base member extending from the support. The apparatus can include an arm coupled with the base member at a second end of the base member, the arm extending from the base member to fit within an opening in a vessel. The apparatus can also include a welding head coupled with the arm, the welding head to weld a welding interface at an interior surface of the vessel.
