Modular Pipe Welding Structure for Adjustable Hole Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe welding structures for connecting pipes to channels in plates face challenges in adjusting the depth of the through hole and ensuring accurate heat application, especially when dealing with thin-walled pipes, which complicates the welding process.
Innovation Solution
A pipe welding structure that involves stacking multiple through-hole plates to create a combined through hole of adjustable depth, with grooves around the welded area to control heat diffusion and prevent peripheral cutting, and a relay channel plate for fluid communication, allowing for easier welding and precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the depth of the through hole is adjusted by changing the thickness of the plate, then the depth adjustment is achieved, but it becomes difficult to adjust freely because general-purpose plate materials have standardized thicknesses
Solution Approach 1:
The through-hole structure is divided into multiple separate through-hole plates (first through-hole plate, second through-hole plate, etc.) that can be stacked in different combinations. Each plate has a standardized thickness, but by varying the number and arrangement of plates, the total depth of the combined through hole can be freely adjusted to match different pipe requirements without needing custom plate thicknesses.
2Strength
If the pipe is welded to the through-hole plate, then the connection is achieved, but accurate heat application becomes difficult especially for thin-walled pipes
Solution Approach 1:
Grooves are formed around the welded portion on the through-hole plates to create localized heat control zones. These grooves act as heat barriers that prevent excessive heat diffusion to surrounding areas, allowing for more precise heat application during welding of thin-walled pipes while maintaining strong welded connections.
3Adaptability or versatility
If multiple through-hole plates are stacked to adjust depth, then depth adjustability is improved, but the structure becomes more complex
Solution Approach 1:
The multiple through-hole plates are designed with identical or similar structures, each serving the same function of providing a through hole and serving as a welding surface. This standardized modular design allows the same component type to be used in different quantities and arrangements to achieve various depth requirements, simplifying manufacturing and assembly despite the increased number of components.

Function Achieved in This Case
Facilitates adjustable depth settings for the through hole, enhances welding accuracy by controlling heat distribution, and improves the fusion of the welded portions, making the process more efficient and reliable.
Implementation Method 1
the pipe being welded to one of the plurality of through-hole plates that is disposed farthest from the channel plate
Implementation Method 2
at least one groove being formed in each of the plurality of through-hole plates around a welded portion that is a portion of the plurality of through-hole plates welded to the pipe

AI summary
A pipe welding structure includes: a channel plate that includes a fluid channel; through-hole plates stacked on the channel plate, each of the through-hole plates having through holes that communicate with each other and forming a combined through hole; and a pipe inserted into the combined through hole and welded to one of the through-hole plates disposed farthest from the channel plate, the pipe internally including a pipe channel that connects to the fluid channel.
