The weld metal (WM) was generally regarded as one of the weakest zones in the dissimilar welded joints. The microstructure and fracture mechanism of the multi-pass WM are systematically probed in the present study. The scanning electron microscopy (SEM) results show more voids in the equiaxed grain zone (EGZ) adjacent to the fracture than those in the columnar grain zone (CGZ). https://parisnaturalfoodes.shop/product-category/hot-choc-milk-choc/
