摘要： PROBLEM TO BE SOLVED: To obtain a rational bending condition with a small burden.
SOLUTION: Pipe data and bending condition data are input in a computer and stored (S10 and S20). The analysis by a finite element method is performed by utilizing the input pipe data and the bending condition data, and the shape data before pressing release and the shape data after pressing release are obtained (S30 and S32). A pipe of the shape before the pressing release (the reference bending shape) and a pipe of the shape after the pressing release are divided into a large number of unit areas to calculate the deviation for the corresponding unit area (the unit deviation) (S40). The total of the unit deviations (the total deviation) is calculated (S42). A new bending condition is obtained on the basis of the total deviation (S50).

摘要： PROBLEM TO BE SOLVED: To provide a laser welding method for surface treated steel sheets, a method that enables dry fine solid particles to be used directly as spacers and that thereby eliminates special post treatment such as a drying process to help improving productivity as well as reducing manufacturing cost. SOLUTION: On one 1 of the two plated steel sheets to be welded, there are deposited fine solid particles 3 such as steel beads for shot peening by means of a cladding laser torch having a fine particle passage. Then, on this surface treated steel sheet 1, the other one 2 is superposed through the fine solid particles 3, and subsequently the superposed parts are laser-welded. Between the two plated steel sheets 1, 2, a minute gap is maintained by the fine solid particles 3; therefore, in the laser welding, gasses generated by the evaporation of the metallic components in the plated layers 1a, 2a are discharged outside through the gap, enabling a quality weld metal 5 free from blowholes to be obtained.
