		abstract={Steel API 5L-X60 pipeline is made and manufactured based on a standard API that is the American Petroleum Institute, which pipe has 0.26% carbon content (data journal Iscor Flat Steel) that is classified in the medium carbon steel. In books (Wiryosumarto, 2000) are mentioned carbon steel weldability have a good enough level, compared with a high carbon steel.
Held goal of this research is to improve the resilience of the violence and the structure of the test results obtained mikro.Dari conclusion to heat treatment with the standard temperature, 750, 800, 850oC which consists of the base metal, and Haz Las parent that for the metal (base metal) of steel API 5L-X60 violence are best obtained at a temperature of 750oC with a value of 49,000. In the areas LAS.}
