OXY/Acet Welding

admin

Got a Oxy/ Acet set-up for Christmas. What type of rod can I use and do I need flux. (1/8 mild metal ) Took alot of welding classes in High School (longer than I care to remember) so I hope some of the skills I learned will come back.
Reply:Well, you can use steel, or brass, phosphor bronz, aluminum, and a few other specialty rods, it all sort of depends on what you're trying to glue together.If you learned to gas weld many years ago, it will come back fairly quick once you light up.Appreciation Gains You Recognition-
Reply:A well balanced neutral flame is used for welding most steels. To be sure that the flame is not oxidizing, it is sometimes used with a slight acetylene feather. A very slight excess of acetylene may be used for welding alloys with a high carbon, chromium, or nickel content. However, increased welding speeds are possible by using a slightly reducing flame. Avoid excessive gas pressure because it gives a harsh flame. This often results in cold shuts or laps, and makes molten metal control difficult.Oxides of all ordinary commercial metals have higher melting points than the metals and alloys (except steel) have themselves. They are usually pasty when the metal is quite fluid and at the proper welding temperature. An efficient flux will combine with oxides to form a fusible slag. The slag will have a melting point lower than the metal so it will flow away from the immediate field of action. It combines with base metal oxides and removes them. It also maintains cleanliness of the base metal at the welding area and helps remove oxide film on the surface of the metal. The welding area should be cleaned by any method. The flux also serves as a protection for the molten metal against atmospheric oxidation.The oxyfuel welding rod, which is melted into the welded joint, plays an important part in the quality of the finished weld. Good welding rods are designed to permit free flowing metal which will unite readily with the base metal to produce sound, clean welds of the correct composition. Welding rods are made for various types of carbon steel, aluminum, bronze, stainless steel, and other metals for hard surfacing. Maine Welding Company & Wrought Iron Powered by Custom Web Development

Reply:Carbon steel welded to Carbon steel with Oxygen and Acetylene needs no flux for welding, but needs to be as clean as possible.  RG-45 or 60 can be used and a coat hanger in an emergency.  JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases.  There all here. :
