"WebGalling (or seizing) refers to the problem of two contacting surfaces, such as mating screw threads, seizing up as a result of cold welding. This is a common phenomenon in tightening (and untightening) of stainless steel fasteners.

WebCold welding is a process where metals are joined without heat. The method uses solid-state welding, where no molten or liquid phase is present in the joining process. Cold … WebIn the extreme, galling leads to seizing - the actual freezing together of the threads. If tightening is continued, the fastener can be twisted off or its threads ripped out. Carpenter Technologies, the fastener industry's largest supplier of stainless steel raw material, refers to this type of galling in their technical guide as "cold welding."

WebGalling is also known as cold-welding. This is the process that can happen when the surfaces of a nut and bolt threads are placed under pressure. They begin to weld … WebJul 25, 2024 · Thread galling can occur with standard fasteners when pressure and friction cause the bolt threads to seize to the threads of a nut or a tapped hole. Severe galling, known as “cold welding”, can cause the two surfaces to fuse together, which makes the joint impossible to remove without cutting the bolt or splitting the nut.

WebGalling At high stresses, much stronger bonds form over a greater contact area; gross surface damage occurs, and the equipment may even seize or "freeze-up.'' This latter gross damage is usually referred to as galling, and it may take place after just a few cycles of movement between the mating surfaces. Definitions of Wear and Galling
