How does a steelwork contractor choose a welding method?


How does a steelwork contractor choose a welding method?

The steelwork contractor selects methods of welding each joint configuration that will achieve the performance required. Strength, fracture toughness, ductility and fatigue are the significant metallurgical and mechanical properties that must be considered.See all results for this questionsp.info What kind of welding is used on composite floors?In buildings, composite beams require the welding of shear stud connectors to members, either directly to the top flange or more commonly through permanent galvanized steel decking on composite floors, where the top flange of the beam is left unpainted. Stud weld on a bridge girder (Image courtesy of Mabey Bridge Ltd.) Through deck stud weldingSee all results for this questionsp.info What should the silicon level be for welding galvanized steel?Excessive silicon can cause zinc to penetrate the weld metal, leading to cracking, especially when the zinc coating is thick. The silicon in welding electrodes should not exceed 0.85%; this means that commonly used ER70S-6 filler metals should not be used when welding galvanized steel.See all results for this questionsp.info Basic Information of Steel Structure Building-WANJINLONGAug 15, 2020 · 3.9 Main steel structure——welding material.
