Abstract:
A method of manufacturing multiple kinds of products in an arbitrarily selected order in one manufacturing apparatus by combining, through welding, a plurality of parts belonging to each of said multiple kinds of products, said method comprising of steps of:combining, through welding, a plurality of members constituting each of the parts in each of part assembly lines which is prepared for each of the parts to thereby assemble each of the parts; tack welding the plurality of parts to thereby assemble the products; and thereafter, reinforce-welding the products in a reinforce-welding line, said combining step including the further step of using a uniform number of welding points for each of the parts in each of said part assembly lines for all of said multiple kinds of products, and when the number of welding points of each of the parts are reduced from a required number of welding points, welding the parts at each of the reduced number of welding point in said reinforce-welding line.
