WebMay 22, 2024 · Abstract: The welding residual stress of lap joints of thin steel sheets was measured by the cosα X-ray diffraction method and compared with the numerical simulation. The longitudinal residual stress in the region near the weld is close to the yield strength of the base metal. The welding residual stress distribution is asymmetrical on … WebFeb 12, 2024 · Slag Inclusions Watch your travel and angle speeds. Going too slowly could cause the arc to trail the weld puddle, resulting in slag inclusions. Use the appropriate … WebMar 4, 2024 · The main reason for the undercut is that the heat of the arc is too high, that is, the current is too high. The incorrect angle between electrode and workpiece, unreasonable oscillation, long arc, unreasonable welding sequence, etc. will result in an undercut. Magnetic polarization of the arc during DC welding is also a cause of undercut. graphing reciprocal trig functions
