A data processing method includes generating a data storing area in a memory space. An area address of the data storing area is designated to a basic I/O control on the user space in a memory. The memory has a user space and a kernel space. A function is called in the kernel space using the basic I/O control. Whether the data storing area is inside the memory space is determined. The area address of the data storing area is set as an argument of the function in a case where it is determined that the data storing area is included in the memory space.

A method for calculating the shape of a bead of a welded part by solving the problem of multiple solutions when the shape causing a recess or undercut in the flange is determined by calculation. The geometry data on the object to be welded, the characteristic parameters of the object and welding environment, and the welding conditions are set. Under the welding conditions, the melting part of the object is inferred by heat conduction calculation. The coordinates are rotated about an axis parallel to the direction of the welding and/or about an axis perpendicular to the welding direction for the inferred melting part. A difference lattice is set for the coordinate-rotated melting part. The displacement of the melting part for which the difference lattice is set is calculated by a curved surface equation.

The invention provides an arc welding monitoring device by which it is possible to easily find how detected data such as a welding current and welding voltage correspond to trajectories of a robot, in other words, welding line information of a welding work. The arc welding monitoring device comprises means,and,for detecting at least either the welding current or welding voltage, a means,for storing the detected data, a means,for storing trajectories of a robot, and a means for displaying, on a screen display, at least either the welding current or welding voltage detected by said detecting means, and the trajectories of the robot stored by the storing means, wherein a range is determined on the trajectories displayed on the screen display, and arc welding monitoring display is enabled in compliance with the range.
