Weld Flank Trajectory

The weld flank profile is the smooth transition from the joint face to the weld surface to minimize stress concentrations and increase mechanical strength.

Physical-Chemical Mechanism of Action

Weld face contour influences stress distribution in the weld. A flat contour distributes stresses evenly, while a steep contour leads to high stress peaks.

Metallurgical Relevance & Risks in Welding

Poor weld face contour can cause stress concentrations and thus cracks and hot cracks. This increases the risk of mechanical failure under dynamic load.

Workshop Practice & Action Guidelines

To ensure good weld face contour, the welding process should be set so that the fusion face transitions smoothly and continuously into the weld metal surface. This requires correct control of temperature and stress during welding.
