TIG Welding Process, Torch Angle, Tungsten Grinding and Stainless Steel. Things to keep in mind when TIG Welding Position TIG torch about an 1/8 of an inch from the surface. TIG Torch angle Once an arc is established, angle the torch about 15 to 20 degrees away from the direction of travel. Filler Material Angle When filler material is needed,

Start welding at point C, figure 12-42, progressing upward to point B. When B is reached, rotate the pipe clockwise until the stopping point of the weld is
Read more →Pipe Welding Process Pipe Welding : General The most commonly used processes for joining pipe are the manual oxyacetylene process and manual shielded metal-arc process. Automatic and semiautomatic submerged arc, inert gas metal-arc, and atomic hydrogen welding are also used. particularly in shop operations. The manual shielded metal-arc process may be used for welding all metals used in piping systems,
Read more →Pipe Welding Pipe welding involves the welding of pipe for the handling of oil, gases, water, and other substances, the operating conditions of which range from high vacuum to pressure of several thousand pounds per square inch. Mechanical joints are not satisfactory for many of these services. Electric arc or oxyacetylene welding provide effective joints in these services and also

With the self-consuming technique, the electrode is dragged across the work and a significant amount of pressure must be applied by the diver. With the manipulative technique, the arc is held as

When welding is done on a vertical surface, the molten metal has a tendency to run downward and pile up. A weld that is not carefully made will result in a joint with excessive reinforcement at the lower end and some undercutting on the surface
