SMAW – Open-Root Pipe Welds – Module ID 29301-16

$20.00

Module One (29301-16) presents shielded metal arc welding (SMAW) of open-root pipe joints. SMAW is a wellestablished form of welding used extensively in commercial and industrial applications around the world. One routine use of SMAW is for joining pipe of various thicknesses and diameters. The most common joint used for these applications is the open-root V-groove joint. This module describes how to prepare and perform openroot V-groove welds on pipe in all positions using SMAW equipment and electrodes.
