Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipe welding apparatuses lack an effective mechanism to maintain accurate positioning between the torch and the pipe during rotation, leading to inefficiencies and increased risk of welding defects.
Innovation Solution
A pipe welding apparatus with an automatic position regulating device, including a support, a torch, and multiple rotation parts (circumferential, axial, and horizontal) with a sensor system to ensure precise alignment and initial welding position, allowing the torch to adjust and maintain accurate positioning relative to the pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regular welding apparatus with fixed installation is used, then the welding apparatus can be stably positioned, but it cannot maintain accurate alignment between the torch and the rotating pipe
Solution Approach 1:
The patent applies dynamics by enabling the welding apparatus to rotate together with the pipe through a rotation mechanism. The torch assembly is coupled to the pipe via rotation parts that allow synchronized rotation, transforming the static fixed installation into a dynamic system where the torch maintains its positional relationship with the pipe throughout the rotation process, thus maintaining alignment accuracy while the pipe rotates.
2Productivity
If the pipe is rotated during welding operation, then welding efficiency is improved, but maintaining the correct posture and position relationship between torch and welding line becomes problematic
Solution Approach 1:
The rotation mechanism allows the pipe to rotate during welding, improving productivity by enabling continuous welding without stopping for repositioning. The torch assembly dynamically follows the pipe's rotation through the coupled rotation parts, automatically maintaining the correct posture and position relationship without requiring manual intervention, thus solving the ease of operation problem.
Solution Approach 2:
The welding apparatus has self-service capability through the automatic position regulating device. The sensor detects the pipe's position and the rotation mechanism automatically adjusts the torch's position and orientation to maintain accurate alignment, eliminating the need for continuous manual adjustment and making the system self-regulating during the welding process.
3Manufacturing precision
If multiple rotation parts and sensor systems are added to maintain accurate positioning, then welding precision is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components. The rotation parts are coupled together in a compact arrangement where the first rotation part, second rotation part, and third rotation part work in coordination as a unified rotation mechanism. The sensor system is integrated with the position regulating device, combining detection and control functions into a cohesive system that achieves high precision without excessive complexity.
