Solution Overview
Problem
Traditional dual wire welding torches face challenges in optimally maneuvering welding wires along the roots of butt joints, leading to sub-optimal joint integrity and requiring costly and time-consuming joint preparation, such as beveling, to position wires correctly, which can result in irregular fusion and increased energy consumption.
Innovation Solution
A dual wire welding torch design featuring non-coplanar and divergent welding wire guides that orient the wires in a specific angular relationship, allowing them to be positioned optimally without the need for joint preparation, thereby maintaining precise control and reducing magnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dual wire welding torches are used with coplanar wire guides, then the device structure is simple, but the welding wires cannot be positioned optimally at joint roots leading to poor joint integrity
Solution Approach 1:
The patent transitions from coplanar wire guides to non-coplanar wire guides, where the guides are oriented at different angles in three-dimensional space. This dimensional change allows the welding wires to be positioned at optimal locations at the joint roots while maintaining wire guide structure that is manageable in complexity.
Solution Approach 2:
The wire guides are configured with asymmetric angular relationships, where each guide is oriented at a specific angle relative to the welding direction and to each other. This asymmetric configuration enables optimal positioning of wire tips at the joint roots, improving joint integrity without requiring complex adjustable mechanisms.
2Ease of operation
If joint preparation such as beveling is performed to position wires correctly, then wire positioning is improved, but manufacturing time and cost increase
Solution Approach 1:
The wire guides are pre-configured with specific angular orientations designed to automatically position the wire tips at the optimal location at the joint roots. This preliminary configuration of the wire guides eliminates the need for preliminary joint preparation such as beveling, saving manufacturing time while ensuring proper wire positioning.
Solution Approach 2:
The non-coplanar wire guide structure is designed to self-position the welding wires at the correct angles and locations without requiring external joint preparation. The guides inherently provide the necessary geometric constraints to achieve optimal wire positioning directly during the welding process setup.
3Use of energy by moving object
If welding wires are positioned close to joint roots, then energy consumption is reduced, but wire maneuverability becomes difficult
Solution Approach 1:
By configuring wire guides in non-coplanar arrangements with specific angular relationships, the patent enables wire tips to reach close to the joint roots in three-dimensional space. This spatial configuration allows optimal positioning for reduced arc length and energy consumption while maintaining wire feedability through the angled guides.
Solution Approach 2:
The patent optimizes parameters such as wire guide angles, wire tip spacing, and guide orientation to enable wires to position close to joint roots. These parameter adjustments maintain wire maneuverability by ensuring adequate clearance and feed angles while achieving the energy benefits of shorter arc lengths.
4Productivity
If multiple welding wires are used in a single torch, then productivity increases, but magnetic interference between wires increases
Solution Approach 1:
The non-coplanar wire guide configuration positions multiple welding wires in three-dimensional space at specific angular relationships. This spatial separation reduces magnetic interference between the wires compared to coplanar arrangements, while still enabling multiple wires to operate simultaneously in a single torch for high productivity.

Function Achieved in This Case
This design enables the formation of uniform, high-quality welds with reduced energy consumption and increased productivity by allowing the welding wires to reach the joint roots without beveling, resulting in stronger, more reliable joints and minimizing material waste.
Implementation Method 1
an electrical arc is generated, passing between the tips of the wires and regions of the workpiece(s) sought to be joined. The electrical arc generates intense heat which melts portions of the electrical wire and the workpiece
Implementation Method 2
the electrical arcs can generate magnetic fields which cause the welding wires to move out of a desired position within the joint

AI summary
A welding torch includes a nozzle with a first welding wire guide configured to orient a first welding wire in a first welding wire orientation, and a second welding wire guide configured to orient a second welding wire in a second welding wire orientation that is non-coplanar and divergent with respect to the first welding wire orientation. A method of welding includes moving a welding torch with respect to a workpiece joint to be welded. During moving the welding torch, a first welding wire is fed through a first welding wire guide defining a first welding wire orientation and a second welding wire is fed through a second welding wire guide defining a second welding wire orientation that is divergent and non-coplanar with respect to the first welding wire orientation.
