There are many kinds of welding methods of galvanized pipe, common welding methods are gas welding, manual arc welding, carbon dioxide gas welding, submerged arc welding, tungsten argon arc welding, etc., the following galvanized pipe - Suzhou Jinchixin pipe industry to give you a brief introduction.
In the past, gas welding was used in galvanized pipe welding. Due to insufficient heat input in gas welding, welding defects and poor mechanical properties are easy to occur, which are basically eliminated in the installation industry. Gas welding can do great damage to galvanized layer.
Carbon dioxide gas shielded welding of galvanized steel has good welding performance. High quality welded joints can be obtained when appropriate welding specifications and matching gases and welding materials are used. This method is rarely used in engineering practice.
Argon tungsten arc welding arc energy concentration, less damage to galvanized layer, more easy to form a good single-side welding double-sided shaped joint. This is a worthwhile method of welding, but welding is slow and expensive.
