Interchangeable Nozzle Receptacles for Dual-Wire Torch Angle Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-wire welding torches are inflexible and require multiple units to accommodate different angles of contact tubes or welding wires, leading to increased costs and complexity for various welding tasks.
Innovation Solution
A pair of nozzle assembly receptacles with angled openings (0° to 20°) that can be easily exchanged to adjust the alignment of contact tubes or welding wires, allowing for a single dual-wire welding torch to be adapted for various applications without needing multiple units, along with a cooling system and gas dispenser designed for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dual-wire welding torches are purchased to accommodate different angles of contact tubes, then adaptability for various welding tasks is improved, but cost and device complexity increase
Solution Approach 1:
The welding torch is divided into modular components: a universal torch body and interchangeable nozzle assembly receptacles. Each receptacle is designed with specific opening angles (0° to 20°) to accommodate different contact tube alignments. This segmentation allows users to mix and match receptacles with the same torch body, achieving multiple welding configurations without purchasing multiple complete torches.
Solution Approach 2:
The torch body is designed as a universal platform that can accommodate multiple types of nozzle assembly receptacles with different opening angles. The standardized interface and mounting mechanism enable a single torch body to perform multiple welding functions by simply changing the receptacle component, eliminating the need for multiple specialized torches.
2Ease of manufacture
If fixed-angle contact tubes are used in dual-wire welding torches, then manufacturing simplicity is improved, but adaptability for different welding applications deteriorates
Solution Approach 1:
The system transitions from static fixed-angle contact tubes to a dynamic configuration where the nozzle assembly receptacle angle can be changed. The receptacles are designed with standardized mounting interfaces that allow quick interchange between different opening angles (0°, 5°, 10°, 15°, 20°), enabling the welding torch to adapt its geometry dynamically without complex adjustment mechanisms.
Solution Approach 2:
The opening angle parameter of the nozzle assembly receptacle is made variable through the use of interchangeable components. By changing the receptacle with a different opening angle, the system efficiently adapts to various welding applications while maintaining simple manufacturing of individual components with fixed parameters.
3Adaptability or versatility
If interchangeable nozzle assembly receptacles are implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The nozzle assembly is nested within the nozzle assembly receptacle, which itself attaches to the universal torch body. This nested structure allows the compact storage and easy interchange of multiple receptacle types. The receptacles are designed to fit within the same mounting space, minimizing the overall footprint while enabling multiple configurations.
