      1G, 2G, 3G, 4G, 5G, the first thing you think of is the mobile network. However, there are 1G, 2G, 3G, 4G, 5G, 6G in welding industry, which refers to the division of weld position.


      1.The position of weld is divided into 1G, 2G, 3G, 4G, 5G and 6G, which means flat welding, horizontal welding, vertical welding, overhead welding, horizontal fixed welding of pipeline and 45 degree fixed welding of pipeline.
