RESISTANCE SPOT REPAIR WELDING OF SPOT WELDED STEEL SHEET

Materials and Manufacturing Processes, 2005
ABSTRACT Repeated resistance spot repair welding over the poor spot weld and interface fractured spot weld of low carbon steel sheet has been studied. The repair welding has been carried out at different parameters to optimize the welding current, weld time, and electrode force as the primary welding parameters for maximum joint strength.

Optimization of spot-welded structures

Finite Elements in Analysis and Design, 2001
This paper addresses the optimization problem of a spot-welded structure under fatigue life consideration. The so-called umbrella model of spot welds and the radial stresses around a spot weld were introduced into the optimization process. The idea was to study the optimization problem using the type of analysis which is now considered to be valid for ...
