What's the proper arc length for welding alloy?
The proper arc length when welding alloy metals is as tight as possibleon the verge of touching the metal. A tight arc produces a well-defined puddle and better directional control, which is necessary when dealing with a sluggish weld puddle.See all results for this questionWhat kind of pipe is Erw schedule 40?The erw pipes are electric resistant welded from either strips or coils in a longitudinal direction to add strength to the pipe. There are different dimensions and standards of these pipes.

BackgroundThe new NCPWB Welding Procedure Specification numbering system clearly defines the type of metals to be welded, the welding process used and allows for identification of variations in a process. This numbering system will be used on all Welding Procedure Specifications revised or developed in the future. The following describes the new numbering system:Welding ProcedureWelding Pressure Pipeliners and Piping SystemsThis booklet is a guide to welding pipe with Shielded Metal Arc Welding (SMAW) and double ending pipe using automatic welding. Lincoln Electric supplies electrodes, power sources, automatic and semiautomatic wire feeders, submerged arc wire and flux, which are the industry standards for pipeline construction around the world.Walking the Cup TIG Pipe - WeldingThe pipe is 3" carbon steel schedule 40 and the flange is stainless steel. I like to freehand the root pass using a TIG finger because I use a forward and back technique a lot. But after the root pass, cup walking is often the best and quickest way to weld pipe.

GTAW was the official name at one time but it is now commonly referred to as TIG. An even less common name for GTAW is argon welding. In this type of process, shielding gas is used for welding. TIG/GTAW uses tungsten electrodes in the welding process.
Tips for TIG Welding on Stainless Steel | American Welding polished schedule 40 stainless steel pipe Argon arc welding
Proper fit up Proper fit up ensures that only the required amount of filler metal is used. You cant Filler metal The thicker the rod or wire the more heat is required to melt it. Therefore, the Electrode size Common tungsten electrode sizes range from 3/32 to 1-1/4 of an inch. Selecting Electrode geometry A taper of no more than 2.5 times the electrode diameter creates a focused Fingertip and foot control A foot control allows for a more precise control of amperage and Puddle size The weld puddle should be the thickness of the base metal. If the puddle grows too Gas flow and travel speed Keep the gas flowing and directed at the puddle until the orange color Polarity and pulsing Use pulsed gas tungsten arc welding (GTAW-P) with a direct current See full list on awo.aws.orgStainless Steels Welding Guide - Lincoln Electric7.0 Design for Welding Stainless Steels polished schedule 40 stainless steel pipe Argon arc welding..14 8.0 Selection of Filler Metals polished schedule 40 stainless steel pipe Argon arc welding14 9.0 Selection of a Welding Process polished schedule 40 stainless steel pipe Argon arc welding..18 9.1 Shielded Metal Arc Welding 9.2 Submerged Arc Welding 9.3 Gas Metal Arc Welding 9.4 Flux Cored Arc Welding 9.5 Gas Tungsten Arc Welding 10.0 Procedures for WeldingStainless Steel ERW Pipe | SS 304/316 Welded Pipe The Erw Stainless Steel Pipe can range from smaller sizes up to 24 inches outer diameter.
