Photograph images of the four SS joined block samples at different post-processed stages: first column—as-joined of two rectangular bars (each bar with the dimension of 15 mm by 8 mm by 8 mm); second column—EDM cut of the joined sample; third column—after pull testing. Each joined sample has different sintering conditions (a) 1130 °C for 6 h, (b) 1135 °C for 6 h, (c) 1135 °C for 12 h, and (d) 1140 °C for 6 h.
