Abstract

Welding is one of the grafting techniques melt some metals by means of the parent metal and filler metal with or without pressure and with or without metal risers and produce a continuous connection, Welding speed is the speed and the time during the welding process is determined to get the ideal time to do the welding process with the time variation of 1.67 mm / s, 1.11 mm / s and 0.83 mm.s. The microstructure is a picture of a collection of phases that can be observed through metallographic techniques. The microstructure of a metal can be seen with a microscope. , Microscope that can be used is the microscope optical and electron microscopy .. Planning Welding SMAW welding using welding procedures using structural steel ST 37. , Material testing procedures using the standard test ASTM E08. Testing test material using a tensile test to determine the tensile strength of the material and micro-structures to observe changes in the form of atomic structure due to changes in the heat in the welding process. Selection of electrodes using E6013 electrode material based to the overall economy to provide information to the general public. , Based on the welding procedures used by the planning welding connection which consists of 15 welding procedures are determined and summarized into a welding procedure
