Weld Geometry
Weld geometry refers to the external and internal dimensions of a weld, such as width, height, and groove angle. These dimensions determine the mechanical strength and appearance of the joint.
Physicochemical mechanism of action
The weld geometry influences the stress distribution in the weld. An optimal geometry leads to an even load distribution and prevents stress concentrations that could trigger cracks.
Metallurgical relevance & risks when welding
An uneven weld geometry can lead to high stresses, causing cracks or distortion in the component. A weld that is too thin might not be strong enough, while one that is too thick adds material cost and makes the part heavier.
Workshop practice & instructions
Make sure the weld has the specified dimensions. Use specific tools and settings for each type of weld joint. Check the weld geometry regularly with a microscope or other inspection method to ensure it meets the standards.
