DJ Radakovic Resistance Spot Weld FailureModes in Shear Tension Testing of Advanced High-Strength Automotive Steels3.1 Identify Gaps: In the above research papers, we found that resistance spot welding machine is very bulky and undergoes a time-consuming welding cycle, i.e. it doesn't. joining materials instantly, creates a larger heat zone that requires longer cooling time and is susceptible to shear failure. It also doesn't weld at any angle, requires a proper foundation, and is expensive. 3.2 Objective: To create a welding machine that: -• Can weld at any angle and any height • Is flexible • Is less expensive • Compact in size • Provides ease of use for the welder and • Less than weight. • Is portable • Does not require a rigid foundation. Chapter 4: Design and Modeling 4.1 Equipment Components • 17 gauge copper wire for primary winding • Fiberglass coated aluminum for secondary windings • Step-down transformer • Electrode • Brass electrode clamp • Limit switches • Stamping (plates) • Wooden case • Nut bolt • Wire for main current supply 4.2 General equation used in spot welding The shear strength of a single weld spot can be calculated as follows: τ = 2.6 • t • d • RmWhere:τ = shear strength, N t = thickness of the sheet, mm d = diameter of the weld, mmRm = tensile strength of the material, MPaThe electrodes sink at least slightly on the surface of the workpiece. ...... middle of paper ...... works and weighs almost 200 kilos. In this project we removed the problems mentioned above by creating a much simpler, lighter, portable, compact and flexible machine, capable of welding at any angle and can be easily operated by a less experienced worker with a lot of ease and the precision required. The advantages of our equipment are:- • Welding at any angle, any height • Offers flexibility • Less expensive • Compact • Provides ease of use for the welder and • Less weight.We conclude that our machine can be mass produced and can also be used for industrial purposes.Chapter 8: References1.
