Summary:PROBLEM TO BE SOLVED: To solve such a problem that the powder etc. to be transported is leaked from the joint, since there is no other choice than providing a lead part when producing a joint part from the sheet of the raw material with a welding method that presses a heated object by a general-purpose press machine when the joint such as made of urethane rubbers is mounted on the gap between the pipings.SOLUTION: A defect of the joint such as being made of urethane rubber is removed by removal of the lead part by using not a general-purpose press machine but a dedicated press machine with the view of above status, without providing a lead part, and by making the part to be welded overlapped, heated and pressed.
