Infrared measurement and research of temperature distribution during discontinuous welding

ZENG Zhi1,2,WANG Lijun1,2,WANG Yue1,2,ZHANG Han3(1.School of Materials Science and Engineering,Tianjin University,Tianjin 300072,China;2.Tianjin Key Laboratory of Advanced Joining Technology,Tianjin 300072,China;3.Julong Steel Pipe Co.,Ltd,Hebei 062658,China)  
The discontinuous welding process of 5A06 aluminum alloy ribbed panels cylinder was measured and researched by the Thermal Imaging Infrared System.The emissivity and radiosity in the thermal image follow exponential decay according to the Infrared System working principle,and the emissivity of 5A06 aluminum alloy was determined.To deal with the particularity of the structure and shooting angle,based on the relationship between pixel distance and true size,the temperature data in heat image was reverted into the temperature distribution of welding seam by discrete local coordinate systems.Comparing with the heat-circulation,it is found that the formed welding seam warms up the latter ones,the temperature peak value of latter seams was raised;the weld microstructure was improved during the discontinuous welding,and the grain in the HAZ had been coarsed.
