The weld joints are prepared by using different combination of pulse parameters. In conjunction with this method, the narrow groove (3 bevel) was shown to provide significant technical advantages.« lessĬharacteristics of Extra Narrow Gap Weld of HSLA Steel Welded by Single-Seam per Layer Pulse Current GMA Weld Depositionīutt weld joints are produced using pulse current gas metal arc welding process by employing the technique of centrally laid multi-pass single-seam per layer weld deposition in extra narrow groove of thick HSLA steel plates. Analysis showed machine-made (automatic) gas tungsten arc welds (GTAW) as the method of choice due to cleanliness and superior mechanical properties. The utility companymore » then proceeded to determine the most effective method to complete this work.
Although increased inspection was much costly, pipe replacement was chosen due to potential safety concerns with seam welded pipe even with more frequent inspection. With this in mind, the utility company evaluated replacement of the seam welded hot reheat pipe with seamless pipe or increasing the frequency of its inspection program. The overriding consideration, however, was one of safety. Alternatives were narrowed to two in dealing with the installed seam welded pipe. Southern California Edison, recognizing a potential safety concern, scrutinized its existing seam welded hot reheat pipe manufactured by the same supplier as that which failed. Replacement of seam welded hot reheat pipe using narrow groove GTA machine welding The diffusers are of a transverse width which is on the order of the thickness of the electrode so that the diffusers can, in use, be inserted into a narrow welding groove before and after the electrode in the direction of the weld operation. The diffusers extend downwardly along the torch electrode on opposite sides thereof so as to release shield gas along the length of the electrode and at the distal tip of the electrode. First and second tapered diffusers are respectively connected to the manifold sections in fluid communication with the gas passages thereof. Laterally extending manifold sections communicate with a shield gas inlet such that shield gas supplied to the inlet passes to gas passages of the manifold sections.
The diffuser assembly includes a manifold adapted for adjustable mounting on the welding torch which is received in a central opening in the manifold. Now, it’s time we make our videos accessible.Narrow groove welding gas diffuser assembly and welding torchĪ diffuser assembly is provided for narrow groove welding using an automatic gas tungsten arc welding torch. YouTube, Instagram, TikTok, and other streaming video apps are accessible globally. As a creator, don’t block people from becoming your viewer, your follower, a part of your community. Making videos more accessible is fundamental to content, connection, and communication. “Lost in translation” will now be lost in our memories. In seconds, you’ll have your video automatically translated with subtitles. Simply upload your video, select the language you want to translate to from a list over 60 different languages. Kapwing’s online video translator lets you generate subtitles that are automatically translated in real time. Online transcribers today is only one step closer to accessibility. Today, most streaming platforms provide auto-transcribers like YouTube’s auto-generated captions and TikTok’s automatic caption generator. The problem is: there’s a language barrier. Oftentimes we find funny TikTok videos, delicious recipes on YouTube, or Facebook Reels life hacks that we want to show our parents, friends, or family.
