Bead geometry modeling on uneven base metal surface by fuzzy systems for multi-pass welding

作者：

Highlights：

• A fuzzy system-based weld bead profile model is proposed for multi-pass welding.

• Unevenness of the base metal surface is considered in the welding groove.

• Bead characteristics and shape are reconstructed from estimated profile coefficients.

• Experimental validation demonstrates the adequacy of the proposed model.
