Paper technology turns into cash - Weld purging with water-soluble paper saves shops money.

摘要

Shops face several options in selecting a purge dam material that best handles their GTAW or TIG pipe and tube-welding applications. One simple technology, which has been around for years, is water-soluble paper, This technology doesn't harm the environment, is easy-to-use, and saves shops money. Weld purging is used in welding stainless steel and other high-value alloy pipes and tubes in applications involving nuclear power plants, fabrication jobs, chemical plants, paper mills, and pipelines. In this process, an inert gas, typically argon, removes, or purges, the air (oxygen) around the weld area, This ensures high-quality welds and guards against defects such as discoloration, brittleness, and cracking.
