1. Cooling times in case of manual arc welding process with covered electrodes, generally, are remarkably smaller than those of three welding processes, namely, submerged arc welding process, C. S. arc welding process and argon arc welding process. 2. A cooling time in case of C. S. arc welding process is nearly equal to those of argon arc welding process, if the same arc energies per unit bead length and the same thickness of base plate are adopted in both cases. 3. Cooling times in case of submerged arc welding process differ slightly from those of C.SS. arc welding process or argon arc welding process, and the differences are due to plate thickness and arc energy per unit bead length. 4. The cooling time S is proportional to J=(60EI/v)^n, and the value of n changes according to the plate thickness generally, and decreases with increase of the plate thickness. This tendency was confirmed experimentally and theoritically.
