Variables Used
Efficiency of Welded Joints - The Efficiency of Welded Joints refers to the strength of a welded joint with respect to the strength of the base metal.
Tensile Force on Welded Plates - (Measured in Newton) - Tensile Force on Welded Plates is the stretching force acting on the plates that are welded.
Tensile Stress in Weld - (Measured in Pascal) - Tensile Stress in Weld is the average stress experienced by the Weld Beads when the joint plates are brought to tension.
Welded Base Plate Thickness - (Measured in Meter) - Welded Base Plate Thickness is defined as the thickness of the base plate that is welded to another plate.
Length of Weld - (Measured in Meter) - The Length of Weld is the linear distance of the welding segment joined by the welded joint.
STEP 1: Convert Input(s) to Base Unit
Tensile Force on Welded Plates: 16.5 Kilonewton --> 16500 Newton (Check conversion here)
Tensile Stress in Weld: 56.4 Newton per Square Millimeter --> 56400000 Pascal (Check conversion here)
