Abstract
PURPOSE: To surely check the weld defect portions where pinholes, etc., exist in the weld zone by welding a top band to the tank made of iron plate, fusion-welding a sealing seat having a communicating hole between the faying surfaces thereof and force-feeding compressed air between the faying surfaces through the hole.
CONSTITUTION: A top band 1a is welded at a weld zone 8a to the tank body 1 made of iron for which airtightness is required. Next, a sealing seat 11 provided with a hole 11a is contacted and welded 8 between the faying surfaces of the tank 1 and top band 1a. In this way, the faying surfaces of the tank 1 and top band 1a are communicated with the outside through the hole 11a of the sealing seat 11, Next, soap water is coated on the weld zones 8, 8a, after which a hose 10 is connected to the hole 11a and compressed air is force-fed. The compressed air enters the clearance existing in the faying surfaces of the tank 1 and top band 1a through the hole 11a and the slight clearance existing in the faying surfaces between the sealing seat 11 and tank body 1, causing the soap water to bubble in the weld defect portion. Thus, the defect portion may be readily checked. Finally, the hole 11a is padded by welding and is closed.
