The forming process and influencing factors of laser forming of TA15 titanium alloy sheet metal are researched.The effects of line energy and area energy on sheet metal bending were notable.The bending rate did not increase linearly with line energy rising.When the line energy increased to a certain value,the bending rate decreased gradually for material surface melting.The influence of sheet thickness on laser forming was also studied.Compared with 3mm sheet,1.5mm sheet was bended easily and more sensitive to the parameters.The metallurgical structure showed that the structure of heating area was divided into fusion zone,heat affected zone and intermediate zone.
