The weldment shown in the figure is subjected to a static force of 100 kN. The hot-rolled steel bar has a thickness h=6 mm and is of AISI 1015 HR steel. The vertical support is AISI 1015 HR steel. The electrode is given in the table below. Use the welding code method. (a) is the weld metal strength satisfactory? (b) Is the attachment strength satisfactory? h h=6 mm b=60 mm d=90mm electrode=E6010 |-b- h F

1/2-inch thick steel bar is welded to the vertical supportA) Calculate the allowable load if the electrode is E7018, the bar is 1015 cold drawn steel, the support is 1020 cold drawn steel.

Q1: The weldment shown in the figure is subjected to a force F. The hot-rolled steel bar has a thickness h and is of AISI 1040 steel. The vertical support is likewise AISI 1040 HR steel. The electrode is given in the table below. Estimate the static load F the bar can carry if two fillet welds are used. b (mm) h (mm) d (mm) 70 Elecrode E8010 30 6 1-b- F

E70XX 1/4 V2 1/4 For the welding information shown, calculate the design capacity of the weld Rweld = k

An angle iron made of AISI 1040 CD steel is welded to metal as shown and loaded with a dynamic load varying between +40kN and +60kN. E70XX (Sut = 482MPa, Sy = 393MPa) will be used as the welding electrode. Find the factor of safety of the weld zone. Note: that both static and dynamic loads are applied to the source.

Çubuk Mafsal Çatal Mafsal F2 60° F1 Şekil 1: Halat makara sistemi In Figure 1, m=800 kg load is carried by the rope-pulley system. The reel is fixed to the fork with a pin. The fork is welded to the bar made of 1030 annealed steel with a circumferential corner seam. I. It is a quality weld and is under medium impact. Calculate the diameter of the bar for factor of safety 6. If the factor of safety is 6 and calculate the weld thickness.

3.) The diagram below shows a 5.5m long double angle brace which is connected by 6mm welding connection. The length of weld shown in the picture is 300 mm on the top and 100 mm on the bottom. The 2-L127x 89x6.4 are 300W steel and long leg back-to-back. The braces are to be welded to a 12 mm 350W steel gusset plate. Determine the factored tensile capacity of the angles. Any intermediate connections that are required should also be specified. 740 kN -12 mm Gusset Plate

i need correct explanation my best wishes ton

Situation 2: The lap splice shown will develop a full strength as shown in the figure. Using E70 electrodes. The width of the plate is 150 mm and the thickness is 10 mm. Use Fy = 248 MPa T4 46 mm 48 mm 1. Which of the following nearly gives the diameter of the slot weld using the LRFD method. O 45 mm T O 47 mm T W
