The horizontal line called the reference line is the anchor to which all the other welding symbols are tied. The instructions for making the weld are strung along the reference line. An arrow connects the reference line to the joint that is to be welded. In the example above, the arrow is shown 40crz special structural steel Submerged arc welding
High Strength Steel TMCP and QT Plates for Heavy Structures
Charpy-V-temperature transition curve in the heat affected zone of a S355ML after welding with submerged arc welding (3,0 kJ/mm). Due to the higher carbon content and the risk of hydrogen-induced cracking a conventional S355J2G3 in thickness above 30 mm is normally preheated prior to welding. Submerged Arc Welding wire - SAW welding wireNiCu-alloyed wire electrode for submerged arc welding of weathering steels and special structural steels in steel construction as well as plant and bridge construction. AWS A5.23: EA3 Mo-alloyed wire electrode with higher Mn-content for submerged arc welding of fine grain steels, pipe steels and heat-resistant boiler and vessel steels.
