Portable Welding Process Module for Long-Distance Advanced Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding equipment in shipyards often faces challenges due to its large size and weight, making it difficult to navigate through tight spaces and causing operator fatigue, and long digital control cables reduce reliability and increase complexity in welding processes.
Innovation Solution
A portable advanced process module system that separates welding power supply and feeder into smaller, suitcase-style enclosures with disconnectable power and communication, using power cables for control signal transmission and potentially incorporating wireless communication, to reduce size, weight, and cable length, enhancing mobility and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If welding equipment is made larger and heavier to provide adequate power, then power supply capability is improved, but mobility and ease of passage through openings deteriorate
Solution Approach 1:
The welding system is divided into separate functional modules: a remote power source unit and a portable welding unit. The power source can be located up to 200 feet away from the welding area, allowing the heavy power equipment to be segregated from the mobile welding components. This segmentation enables the welding unit to be small and light for easy mobility while the power source provides adequate power supply capability.
2Ease of operation
If welding equipment is made smaller and lighter to improve mobility, then ease of passage and operator fatigue are improved, but power supply capability deteriorates
Solution Approach 1:
The power supply function is extracted from the welding unit and placed in a separate remote location. The portable welding unit contains only the essential welding components (torch, wire feeder, control electronics) making it small and light for easy mobility. The heavy power source is taken out and positioned remotely, connected via cables, thus providing full power supply capability without burdening the mobile welding unit.
3Adaptability or versatility
If long digital control cables are used to connect remote power sources, then flexibility in positioning is improved, but reliability and system complexity deteriorate
Solution Approach 1:
The control signals and power transmission are merged into a unified communication protocol over the power cables. Rather than using separate digital control cables, the system uses the existing power cable infrastructure to carry both power and control signals. This merging eliminates additional cables, reduces system complexity, and improves reliability by using fewer connection points.

AI summary
A portable advanced process module system includes, for example, a welding power source, an portable advanced process module, and a wire feeder. The portable advanced process module and the wire feeder are separately enclosed in suitcase style enclosures with disconnectable power and communication means between the portable advanced process module and the wire feeder. The processing unit includes power electronics to enable advanced weld processes that can be delivered to the wire feeder and a welding work piece. The portable advanced process module is powered by a DC bus that can be supplied by a welding power source. Connecting the portable advanced process module between the welding power source and the wire feeder enables advanced welding processes to be accomplished at great distances from the main welding power source. Separating the power electronics into the portable advanced process module and maintaining a standard suitcase wire feeder form factor keeps the welding equipment used in the working area envelope small, light, and portable.
