        Glasses are important topic in automotive manufacturing industry. Always automotive glasses because of safety and beauty are attracted attention by big automobile manufacturing companies and with development of the automotive industry, significant progress has been occurred in the glass industry. Today different types of glasses are used with various applications based on the needs. The different requests in the automotive industry, glass artisans have tried to turn into producing variety glasses. For example the first automotive front glasses were common glasses which because of rapid breakage during the accident and its dangers for passengers, unbreakable glasses have been produced to prevent passengers from smashed glass injuries. After that has been thought to produce PVB glass for raising the passenger safety, improving the quality and increase refractive index of glass. Laminated glass almost has been used in front glass of car for more safety and strength and also tempered glass has been use in order to behind and back glass. Manuscript profile

        In the present study, Dissimilar welding of austenitic   stainless steel AISI 304L to Quenched and Tempered Steel ASTM A514 was investigated by gas tungsten arc welding process. Two filler metals including (ERNiCr-3) and austenitic stainless steel 309l (ER309L More
        In the present study, Dissimilar welding of austenitic   stainless steel AISI 304L to Quenched and Tempered Steel ASTM A514 was investigated by gas tungsten arc welding process. Two filler metals including (ERNiCr-3) and austenitic stainless steel 309l (ER309L) were used. Microstructure of nugget, heat affected zone, inter face and unmixed zone (UMZ) was studied by optic microscopy and scanning electron microscopy equipped with energy disperse spectrometry (EDS). The investigations showed completely austenitic structure as dendrite for ERNiCr-3 weld metal and primary ferrite with austenitic matrix for 309l weld metal. Mechanical properties including tensile and bending strength, impact resistance, hardness and fractography of the specimen was studied. The entire specimen underwent ductile fracture in HAZ in the tension test. Tensile strength in ER309L and ERNiCr-3 had increment of 556 Mpa and 593 Mpa respectively. Impact thoughtless in join induced by ERNiCr-3 filler was 117 J while it was 95 J for ER309L. The maximum and minimum hardness was related to the ERNiCr-3 (156 Vickers) and ER309L (127 Vickers), respectively. Finally, according to mechanical properties, it can be concluded that in dissimilar welding of austenitic stainless steel AISI 304 L to Quenched- Tempered Steel ASTM A514, The ERNiCr-3 filler is better than ER309L.
