Fatigue strength of fillet-weld, plug-weld, and slot-weld joints

Regression Modeling and Process Analysis of Plug and Spot Welds plug weld and slot weld Plug and slot welds are usually used for lap joints They are not suitable for the transfer of high forces and are especially not suitable for dynamically plug weld and slot weld Slot Weld and Plug Weld · Slot Weld: In this method, a plate with a circular hole is placed on the plate to be joined, and a fillet weld is created along the

plug and slot weld symbol To enable thicker plate to be joined by 'spot welding' a circular or elongated hole may be machined through the top plate, enabling either a plug or a slot weld
