Two steel plates having yield point stress of 350 N/mm2 are joined together by double fillet welds of 10 mm thick as shown in figure. The weldment is from the same parent plate material. If the weld has to be replaced by 3 bolts of the same material, one each at A and B and one at mid-way between C and D, design the bolts.

The U-groove is prepared using a milling cutter so the radius of the groove is 3.0 mm. During welding, the penetration of the weld causes an additional 1.5 mm of material to be melted. The final cross-sectional area of the weld can be approximated by a semicircle with a radius of 4.5 mm. The length of the weld is 200 mm. The melting factor of the setup is 0.57 and the heat transfer factor is 0.86.
