Description

Technical Field

[0001] This invention relates to the field of pipe manufacturing technology, specifically a manufacturing process for preparing alloy pipe materials. Background Technology

[0002] The reference patent, titled "A Rapid Preparation Method for Titanium Alloy Pipes" (Patent Publication No.: CN103231218B, Publication Date: 2015-09-30), is based on welding surfacing technology and rapid prototyping using a self-designed rapid prototyping protective device. This method enables the rapid prototyping of titanium and titanium alloy pipes using surfacing welding. The preparation method includes the following steps: fabrication of the protective device cover; pre-purification with protective gas; welding of the weld bead; mechanical cleaning, sizing, and finishing. This invention employs CMT welding technology, using electric arc heat as the heat source to melt metal materials and deposit molten metal material layer by layer along a designed trajectory to achieve rapid prototyping of titanium and titanium alloy pipes. It is also applicable to commonly used metal materials such as steel and aluminum alloys. The size of the pipe can be adjusted by regulating the protective cover to meet the forming requirements of titanium alloy pipes of different sizes. It has advantages such as simple operation, high forming efficiency, simple equipment, low cost, and wide applicability.
