Whether pulsed or non-pulsed welding settings are used depends largely on the material thickness and the requirements for heat input and seam quality.
- For thin materials (e.g. <2mm), a reduced heat input is required to avoid distortion or burn-through. The use of pulsed welding processes is recommended here. These enable precise control of the weld pool with a lower heat input.
- For thicker materials, a higher amount of heat is required to ensure sufficient fusion and bonding. In these cases, conventional (non-pulsed) welding is often used. However, pulsed welding can also be useful, e.g. to minimize spatter or to control the root and cover layers in multi-layer welding processes.
