- Abstract Low carbon steel has suitable physical properties such as: easily to be casted, welded and machined. Generally, this steel is used for construction, hospital and house hold equipment, and so on. Some equipment structures employ low carbon steel pipe for basic construction, in which a lot of brazing joins are applied for connecting each pipe to form a house hold or hospital equipment. This research analyzes the brazing methode, since it is commonly used to obtain smoother joint surface compared with the other method and having lower melting temperature than the pipe. The analysis emphasizes the transformation of mechanical characteristics such as: tensile strength, hardness, micro and macro structures. The result of this research shows that the maximum tensile strength is 509 N/mm2 when the welded groove is 0,5 mm, or 2,35% greater than welded metal strength, and 12,5% less than base metal strength. The hardness values are decreasing compared with the base metal, i.e., 18,5% of average, 18,'57% at IIAZ (Heat AfJJected Zone), and 19,81% of pipe metal under the value of base metal.
