1. A welding system comprising:
a welding robot provided with a torch; and
a welding robot control program creation device,
wherein the welding robot control program creation device is configured to
acquire position information of a welding start point and a welding end point of a weld line on a workpiece, and posture information capable of specifying a posture of the torch with respect to the weld line at a welding teaching point on the weld line, and
create a welding robot control program for performing welding from the welding start point to the welding end point based on the position information and the posture information,
wherein the welding robot is configured to perform welding on the workpiece based on the welding robot control program, and
wherein the welding robot control program creation device is configured to create the welding robot control program to include a posture fixed section in which the posture of the torch is fixed in a three-dimensional space with respect to the weld line during welding from a start point of the posture fixed section to an end point of the posture fixed section.
