If we submerge in welding in different types of materials. The size of the work piece, and uses a different voltage, it will result in the microstructure of the steel changes as material or studies. In SAW By the thickness of the work piece of JIS G 3106 SM490A steel sheet grade (ISO 630) thick 4. Mm welding conditions of the diameter of the wire is hot and SAW a line of 4.8 and 1.2. Mm, respectively, will be structured as a rough edge grain ferrite and experimenting with semi-automatic welding equipment MEMCO (see Figure 1). constant pressure flow flux used is automatically dissolved ADOR Gr II SFA/AWS 5.17 (granular flux) polarity select ADOR 3.15 diameter wire, woven.Ngadaeng coating 400 X 75 X 10 test piece in millimetres, butt joints together and welding. Positions and positive position with flat perpendicular to the sheet. X10 25 mm X 400 jobs are tied to the plate by means of nails, and the tag, and then bring the show has done work and cool down lako. Welded sections are cut by sawing, cutting and sanding the surface with a polishing cloth and Polish with a tattoo with the hots and yard shifts, the endoscope microscope resemble the binary structure. The result depends on the value of the variable parameters.
