@Article{, title={Tribological Characteristics Near Welding Limit for Petroleum Metal Pipelines}, author={Fadhil K. Farhan and Bahjat B. Kadhim and Atheer M. Jameel}, journal={Al-Mustansiriyah Journal of Science مجلة علوم المستنصرية}, volume={32}, number={4}, pages={76-82}, year={2021}, abstract={Welding process is one of the most widely applied processes in the industry. This is due to the ease of the process and it's a quantitative process. The addition of metallic powders to the welding area has not been widely emphasized as a solution to amelioration the tribology characteristic of the welding area therefore the effect of adding metallic powders (SnS nanoparticles) to the welding area on tribology properties was studied. This effect was studied at the values of coefficient of friction, coefficient of wear and wear rate by using the ring – on – disc sliding wear test equipment was used to study the tribological behavior of low carbon steel (A 106 grade B) as pure, 6010 welded and SnS- 6010 welded) under changing loads with constant velocity and in one hour for each run the dry condition at ambient temperature. The results show the coefficient of friction, coefficient of wear and wear rate increased with up load.
