Why shielding gas matters in TIG welding In gas tungsten arc welding (GTAW), inert shielding gas protects the molten weld pool and tungsten electrode from surrounding atmospheric gases. Without this protection, these atmospheric gases can contaminate the weld, causing defects such as porosity and oxidation.

High-strength steels are used across many industries. Get tips for welding high-strength steels so you can get the results you need. High-strength steels in pipe For transmission and process pipe fabrication, some applications require elevated strength and toughness levels. In these cases, high-strength steel may

What is preheating in welding? Preheating in welding helps ensure weld quality and reduces the occurrence of cracking and other problems. Operations commonly use preheat before welding steel or steel alloy pipes or plates that are 1 inch thick or more. Oil and gas, transmission

Why Must Stainless-Steel Pipes Be Purged Before Welding? When engaging in TIG welding of corrosion resistant alloys, such as Grade 304 and 316 stainless-steel pipes, welders are required to purge the interior of the pipe before welding. This process involves utilizing an inert purging gas,

  Q&A: Why Are My Welds Ugly? Learning to weld takes patience and practice. That includes MIG and flux-cored (FCAW) welding. In the beginning, it’s not uncommon for new welders to struggle to make smooth, quality weld beads — or to be uncertain of how

MIG welding aluminum: what you need to know Aluminum, in its pure form, is a relatively soft metal that has many uses. However, it requires the use of alloys to increase its strength. When compared to working with steel, aluminum has unique properties and therefore
