Minor element effect on weld penetration.
QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1990 The penetration in GTA welding is affected by the convective fluid flow in molten pool and the fluid flow is strongly influenced by the minor elements such as sulfur, oxygen and chlorine in base metal. The purpose of this work is to make clear the mechanism of the minor element effect on the fluid flow in GTA welding.In the first, the influence of the ...

A study on bead-on-plate welding of AA7075 using low power fiber laser
Journal of Mechanical Engineering and Sciences, 2016 Laser welding promises the best method to produce higher strength of aluminium joints compared to conventional arc welding process. Arc welding usually produces a large heat affected zone (HAZ), which leads to lower joint strength on aluminium alloys ...

The Effect of Welding Current and Composition of Stainless steel on the Panetration in GTAW
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2012 In this study, welding was performed on the plates of two different types of AISI 316 and AISI 316Ti austenitic stainless steels by GTAW (Gas Tungsten Arc Welding) without using welding consumable in flat position. Automatic GTAW welding machine was used
