Welding the longitudinal shrinkage st (in mm) that occurs during weld- ing is given by the formula 305il sl= 107 iis the welding current in amperes l is the length of the weld in millimeters tis the thickness of the plate in millimeters where suppose an electrode is welded at 125 amp, the length of the weld is 270 mm, and the plate is 16 mm thick. calculate the longitudinal shrinkage that occurs during welding. (round to the nearest thousandth.)
