Resistance welding — Destructive testing of welds — Specimen dimensions and procedure for cross tension testing of resistance spot and the mechanical properties of spot weld in aluminum alloys. The spot weld is currently the joining method of choice in the automobile industry for economic reasons, and this advantage was recog- nized many years ago by the aerospace industry (Ref. 1). Because today steel is the primary material of construction in heating them until they begin to melt at the spot where they are in contact. The molten metal from the two pieces flows together; then the current is turned off and the molten be followed, contact your welding machine manufacturer or refer to RWMA or AWS standards for resistance welding.

HANDBOOK ON WELDING TECHNIQUES. FOREWORD Welding is a very common metal joining technology and it is widely used in Railways in various production and maintenance units. Railways recruit ITI qualified Chapter 13 - Design. Considerations for Spot Welding. Spot welding is often selected for joining sheet. metal fabrications, stampings and assemblies. because it is fast, reliable and economical. However, numerous design considerations can affect the. quality and cost of the weld, among them: size of. the spot weld, accessibility, positioning Here are some of the guidelines on spot welding you can read in this issue: Spot Weld Spacing Spot Weld Overlap Region Spot Weld Tool Clearance Spot Weld To Edge Distance Weld Nut To Edge Clearance If you have any feedback or questions on DFM guidebook, please write to us at info@dfmpro.com Rahul Rajadhyaksha Senior Product Manager Geometric STANDARD ISO 14373 First edition 2006-08-15 Resistance welding — Pro
