Abstract

One of the most usage welding for line-making in steel construction, especially for gas pipes welding, was Submerged Arc Welding (SAW). The basic of SAW used electric current to create arc, so that it could melt filler wire, which the filler liquid in SAW damped in flux. The research aimed to find out the different contain of Mn and Mo in SAW flux to micro structure test and hardeness test in welding line and HAZ region of API 5L – X60 steel. In the research, the writer used API 5LX-60 steel as the material, since the steel made and produced according to API (American Petroleum Institute) standard API 5LX-60 steel with 5L specification was standarded specification by making conference and distribution from line pipe for oil, water, and gas with special usage. The influence of Mn contain would increase the welding metal. The strength also consistent with micro-structure formed, where in the welding there was acicular ferit which was more dominant. Micro ferit acicular AF structure had small grains, the additional Mn would refinement the micro grains, whether in welding metal or reheated region
