Description

Technical Field

[0001] This utility model belongs to the field of welding measurement, specifically relating to a cavity size detection device. Background Technology

[0002] Spot welding is a welding method that uses a cylindrical electrode to form a weld point between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to bring the workpieces into close contact, then current is applied, and the contact area melts under resistance heating. After cooling, a weld point is formed. Spot welding is mainly used for welding thin sheet metal stampings with a thickness of less than 4mm, and is particularly suitable for welding automobile bodies and carriages, and aircraft fuselages. However, it cannot be used to weld containers with sealing requirements.

[0003] Existing spot welding processes often neglect the width dimension of the workpiece, resulting in poor stability of the welded cavity.

[0004] Therefore, we propose a cavity size detection device. Utility Model Content
