Welding Neck Gas Diffuser Threads for Quick 1.5-Turn Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding torches require multiple turns to connect and disconnect gas diffusers from the welding necks, which is time-consuming and inefficient.
Innovation Solution
The implementation of a custom double-start stub ACME thread configuration for the gas diffuser and welding neck, allowing for quick connection and disconnection in approximately 1.5 turns or less.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional screw connection is used to connect gas diffusers to welding necks, then the connection is secure and reliable, but the assembly and disassembly process is time-consuming requiring multiple turns
Solution Approach 1:
The patent modifies the thread parameters by implementing a double-start thread configuration instead of a conventional single-start thread. This changes the lead distance (axial distance per turn) to be approximately 1.5 times the lead distance of conventional threads, enabling the gas diffuser to be connected or disconnected in approximately 1.5 turns or less while maintaining secure connection through proper thread engagement geometry
Solution Approach 2:
The patent creates a dynamic balance between connection security and assembly speed by designing a thread configuration that provides sufficient thread engagement for reliable connection while optimizing the lead distance to minimize the number of turns required. The double-start thread geometry allows the system to achieve both secure fastening and quick assembly/disassembly operations
2Productivity
If a custom double-start stub ACME thread configuration is used to reduce assembly turns to 1.5 turns or less, then assembly speed is significantly improved, but the thread geometry becomes more complex
Solution Approach 1:
The patent divides the threading operation into two independent starts on the same thread form, allowing each start to engage separately and progress independently. This segmentation of the thread into multiple starts achieves the productivity improvement of 1.5 turns or less for assembly while the complexity is managed through the systematic organization of the double-start geometry rather than an entirely new complex mechanism

AI summary
Some examples of the present disclosure relate to apparatus, systems, and/or methods for providing a quick connect and/or disconnect for a gas diffuser and/or neck assembly, for example, in a welding system. The gas diffuser may include threaded grooves and/or protrusions configured to engage with screw threads and/or channels of the neck assembly. The screw threads, protrusions, threaded grooves, and/or channels may be configured such that the gas diffuser may be quickly connected to, and/or disconnected from, the neck assembly.
