Full penetration butt weld

Description:The process is therefore better suited to factory manufacture, although it is used on site where effective shelters can be provided. Metal-active gas welding MAG , process Metal-active gas welding MAG , process MAG welding with flux cored electrode, process is a variation that utilises the same equipment as MAG welding, except that the consumable wire electrode is in the form of a small diameter tube filled with a flux. The design throat thickness determines the depth of penetration required for partial penetration welds. Further informative Annexes in BS EN [7] describe the influence of welding conditions on HAZ toughness and hardness and give useful advice on avoiding solidification cracking and lamellar tearing. The effect may also depend on the precise location and orientation of the imperfection, and upon such factors as service environment and temperature. Completed tests are submitted to the independent examiner for visual examination and non-destructive testing in accordance with Table 1 of the Standard.
