7) For double side parallel fillet weld subjected to an external force 100 kN. The weld has throat thickness of 5 mm and the measured shear stress is found to be 100 MPa. From the above given information find out the length of the welded joint desigN? O 100 mm 50 mm 25 mm 10 mm
Ex Welding.pdf → The Figure shows a 0.75-in-thick AISI 1020 HR steel bar subjected to a load of (F = 1.4 kip) and welded to a vertical support using a 7010 electrode. Estimate the shear stress for the weld. For the AISI 1020 HR steel bar, S, = 30 kpsi, Su= 55 kpsi (from the table) From the pattern of weld shown below, b= d = 2 in (welding table) bd2 * = b/2 ý = d/2 A = 1.414hd Then, A = 1.414hd = 1.414(5/16)(2) = 0.884 in?

1. A butt weld is set on the cross section of an I-shaped beam. There are bending moment M and shear force V at the splicing position, where M=1120 kN•m and V= 374 kN. The beam is made of Q355b steel and semi-automatic weld is used with welding rod E50. The design value of the weld tensile strength f," is 260 N/mm². Please check whether the strength of the butt weld is safe by calculation. 280 M M 0001
T3.2.2 The bracket shown below supports an 18 kN load. The fillet weld extends for full 100 mm length on both sides. What weld size is required to give a safety factor of 3.0 if E60 series welding is used? [Ans. 10 mm] 100 mm 18kN 75 mm Note: There are two 100 mm welds. 1
