ATINY Seam Tracking System:A Solution for Pressure Vessel Welding Automation

　　With the development of China's equipment manufacturing industry,the processing and manufacturing technology of pressure vessels has been greatly improved.As an indispensable piece of equipment in industrial production,pressure vessels are widely used in various industries,including petrochemicals,scientific research,and the defense sector.Pressure vessels not only need to withstand the storage pressure of the medium inside the vessel but also are often affected by the chemical composition of the medium.Any mishap can lead to accidents such as explosions,fires,or leaks.The welding process of pressure vessels affects their safe operation.Therefore,the welding quality of pressure vessels has become an important control point in the manufacturing process.Today,let's explore the solution of the ATINY Seam Tracking System in automating the welding of pressure vessels.


　　Welding Challenges in Pressure Vessels

　　Depending on the location of defect distribution,welding defects in pressure vessels can be divided into external defects and internal defects.External defects are usually visible to the naked eye.Common external welding defects include arc pits,weld beads,improper weld seam shape and size,surface spatter,and undercut.Internal defects include cracks,slag inclusions,gas pores,incomplete penetration,and lack of fusion.Among them,cracks are the most lethal defects affecting pressure vessels and are crucial items that must be detected.

　　Welding defects in pressure vessels can affect their strength,density,etc.,leading to a shortened service life and adverse effects on personal and property safety.By analyzing the causes of welding defects,it is suggested to solve and prevent them in a targeted manner to effectively improve the quality and safety level of pressure vessels.
