Influence of potential Variables in Production Lines on Resistance Spot Weldability of Organic Composite Coated Steels

A Study on Resistance Spot Welding of Coated Steels (Report-2)

Abstract

Investigation was conducted to evaluate potential factors in production lines which might influence resistance spot weldability of organic composite coated steel sheets. Those factors including electrode hardness, electrode downward speed (impact force), water flow rate, spot welding current and a relative location of an organic film to an electrode were selected and examined. The results showed that the sensitivity of this material to these factors is not very much different from that of conventional coated steels and thus this material can be used in established production lines without any special modifications.
