Vanadium mainly exists in the form of carbide in steel plate S690QL and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of steel plate S690QL welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
