Weld seam geometry
Weld geometry refers to the dimensions and shapes of a weld, such as width, thickness, reinforcement, and flank angle. These properties affect the strength, appearance, and mechanical performance of the joint.
Physicochemical Mechanism of Action
Weld geometry determines how much and how strong the metal is provided in the joint. A too thin or too wide joint can affect stress distribution, which can lead to cracking. An uneven flank angle can alter the microstructure and reduce toughness.
Metallurgical Relevance & Welding Risks
Poor weld geometry can lead to stress concentrations that cause cracking or wear of the joint. Uneven reinforcement can alter the microstructure and reduce toughness. An excessive flank angle can overstress the weld metal and lead to stress concentrations.
Workshop Practice & Instructions
Make sure the weld meets the required dimensions and shapes. Use specific material data sheets (MDS) for each type of steel and welding process to determine the optimal geometry. Regularly check the weld geometry with a microscope or other inspection method.
