Non-Circular Weld Wire Orientation for Precise Weld Profile Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional weld wires with circular cross-sections are difficult to orient and control about their axis, limiting the ability to adjust weld characteristics based on orientation, while non-circular wires like elliptical or oval cross-sections offer different weld profiles but require cumbersome adjustments to the welding assembly or workpiece.
Innovation Solution
A guide mechanism with adjustable rollers or pads that correspond to the non-circular cross-section of the weld wire, allowing for controlled orientation and orientation adjustment without altering the welding assembly or workpiece, applicable to various welding systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If non-circular weld wire is used to provide different weld profiles based on orientation, then weld characteristics control is improved, but the complexity of orienting and controlling the wire increases
Solution Approach 1:
The patent introduces a contact tip with a non-circular bore as an intermediary component between the wire feed system and the welding area. This bore acts as a mediator that automatically orients the non-circular wire through its geometric shape, eliminating the need for complex active orientation mechanisms while maintaining precise weld characteristics control
Solution Approach 2:
The wire is pre-oriented during the feeding process through the shaped bore of the contact tip before reaching the welding area. This preliminary orientation action ensures the wire is correctly positioned in advance, avoiding the need for complex real-time orientation adjustments at the welding location
2Manufacturing precision
If adjustments to the welding assembly or workpiece are made to orient non-round wire, then weld orientation control is improved, but the ease of operation deteriorates due to cumbersome adjustments
Solution Approach 1:
The shaped bore in the contact tip serves as a passive intermediary that performs the orientation function automatically through its geometric design, eliminating the need for operators to make cumbersome adjustments to the welding assembly or workpiece
Solution Approach 2:
The system uses the geometric shape of the contact tip bore to automatically orient the wire through its own structure, without requiring external adjustment mechanisms or operator intervention. The bore's shape self-imposes the correct wire orientation through the feeding process

AI summary
An orientation and guide mechanism (100, 200) for a welding system includes a pair of opposed guide members. A weld wire (48) having a non-round cross-section is fed through a guide passageway formed between the guide members, each of which have recessed channels that combine to define the guide passageway. The guide passageway has a non-round shape corresponding to the non-round shape of the wire. The orientation mechanism and the guide members (100, 200) thereof is adjustable relative to a welding device of the weld system, such that the orientation of the wire (48) can be controlled and maintained by adjusting the orientation mechanism (100, 200). The wide side of the wire (48) may be adjusted to be presented to a radiant energy source, and/or the non-round wire may be adjusted relative to the desired weld seam.
