hitsaussäde

Hitsaussäde, or welding radius, refers to the rounded edge or fillet created where two pieces of metal are joined by welding. In fillet welds, this radius is an important geometric feature that influences the strength and stress distribution of the joint. The radius is typically formed by the molten weld metal flowing between the intersecting surfaces of the base materials. A larger hitsaussäde can distribute stress over a wider area, potentially increasing the joint's fatigue life and resistance to cracking. Conversely, a very small or absent radius can lead to stress concentrations at the weld toe, making the joint more susceptible to failure under load.

The size and shape of the hitsaussäde are influenced by several factors during the welding process, including welding technique, electrode angle, amperage, and the speed at which the weld is deposited. Proper control of these parameters allows welders to achieve a desired radius that meets design specifications. In many engineering applications, the hitsaussäde is a critical design parameter specified in welding codes and standards. Inspectors may examine the weld profile to ensure the radius meets the required dimensions, as it directly impacts the structural integrity of the welded component. Understanding and controlling the hitsaussäde is therefore essential for producing reliable and durable welded structures.
