The amount of heat generated by the equipment is between 1600 to 1700 Joules c. The equipment has enough power to weld the steel sheets. d. The equipment does not have enough power to weld the steel sheets e. The amount of heat required is between 700 and 750 JoulesA bracket to be welded into a steel channel using E-60 electrode 345 Mpa) Two welding sets are suggested as shown in Fig. (1)Based on maximum shear stress failure theory and safety factor of (2.5) (a) Find the weld size for each set. (b) Which set would you recommend A or B ?A U-groove weld is used to butt weld 2 pieces of 7.0-mm-thick titanium plate. 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.
