The most frequently used material for steel structure world-wide is EN10025-2 Grade S355JR which is definitely not listed in Table 3.1, but is a 100% weldable steel for the use of the fabrication of steel structures).
Cast Steel. The ability to weld cast steel depends on the alloys:1) If steel castings have over .30% carbon and 20% silicon, it could be a challenge to weld. 2) If the steel alloy contains molybdenum or nickel, and with low carbon content, the steel is easily welded. 3) If the steel has vanadium or chromium, then welding is challenging.
Heat Affected Zone and Weld Metal Properties in Welding Oct 01, 2016 steel structure weldments steelsnbsp; steel structure weldments steels#0183; steel structure weldments steels#32;The weld metal and HAZ are frequently referred as steel weldments. The welding processes, welding consumables, and welding parameters have also influence on these properties. The weld metal micro-structure in C and low-alloy steels contains a variety of constituents, ranging from blocky ferrite, to acicular ferrite, to bainite, to
The publication provides guidance of the requirements for the welding and fabrication of high strength structural steel grades which covers the scope of 7th Edition of the National Structural

Metallurgy Matters:Weldings effect on strengthened steel
- Hardening Techniques and Welding EffectsBenefits of Heat TreatmentHeat Treatment Methods and TipsPreheat and Interpass Temperature for Structural Steels Assuming you are using the right electrode the table below provides safe preheat and interpass temperature for structural steels. Structural steels as defined by AWS D1.1 Structural Welding Code as carbon or low alloy steels that are 1/8 in [3 mm] or thicker with a minimum specified yield strength of 100 ksi [690 MPa] or less.
For stress-relieving steel, the most common temperature range is between 1,100 and 1,150 degrees F. This is high enough to drop the yield residual stresses by 80 percent, yet low enough to prevent any metallurgical changes in most steels.
Steel material properties - SteelConstructionfoStrength  Yield strengtYield strength is the most common property that the designer will need as it is the basis used for most of the rules given in design codes.In European Standards for structural carbon steels (including weathering steel), the primary designation relates to the yield strength, e.g. S355 steel is a structural steel with a specified minimum yield strength of 355 N/mm steel structure weldments steels#178;.
Welding is the Future. Welded structural steel is a stronger and more cost-effective solution, but there are other advantages to using welded structural steel.By utilizing arc welding processes with structural steel products we can reduce the weight of your building by at least a third.
Structural Steel Fabrication for Bridge and Building High Steel in the News - Interview with John O'Quinn. November 22, 2016. From LancasterOnline - John OQuinns long career in the steel industry taught him a lot about what makes High Steel Structures a successful company. I think the rest of the industry has always chased High.

Structural Welding Code SteelThis code covers the welding requirements for any type of welded structure made from the commonly used carbon and low-alloy constructional steels. Clauses 1 through 11 constitute a body of rules for the regulation of welding in steel construction. There are eight normative and eleven informative annexes in this code. A Commentary of the code is
Welding is a core activity in the fabrication factory, undertaken by skilled, qualified operatives working to a welding quality management system under the control of a Responsible Welding Coordinator. It is used to prepare joints for connection in the shop and on

Apr 23, 2018 steel structure weldments steelsnbsp; steel structure weldments steels#0183; steel structure weldments steels#32;Many stainless steels, known for their corrosion resistance, can be welded despite their complex chemical composition. The most important consideration when welding a stainless steel is to know what grade is being welded. There are three major types of stainless steel:austenitic, ferritic, and martensitic. Many ferritic stainless steels are
