Design of Steel Moment Frames Chapter 8 - Metallurgy & Welding 8-1 8. METALLURGY & WELDING Standard industry specifications for construction materials and processes permit wide variation in strength, toughness and other properties that can be critical to structural performance. A588 50 70 MIN. 213 18 A709, GR36 36 58-80 212 20 A709, GR50 50 A572 gr 50 - American Welding SocietyMar 10, 2008 · The procedure we used was a post weld heat treatment (Resistance Heat Treatment ) we controled the cooling rate for three hrs. This seem to work for us. Now if this solves the problem with the rest of the welds we will be happy. IM not convinced that the isues were the welding procedure or the processes. But just the material being welded .
ASTM A242. ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness. The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. Detail - Hobart Brothers Performance Welding ProductsWelding Weathering Steels:Understanding the Material and Choosing Filler Metals for the Job When corrosion caused by rain, snow, humidity, etc. commonly referred to as atmospheric corrosion is of concern in a welding application, weathering steels are often a viable option for the job. What is Corten Weathering Steel?We advise only welding A606-4 or A588 together. Welding A606-4 or A588 to other metals can lead to a dissimilar metal reaction. Please note, there isn't a specific welding wire for ASTM A847 HSS tube and pipe. We advise using the above flux combinations and using your local welding supply company for welding materials.
Lime basic electrodes, inert-gas welding wire, and wire/power combinations equivalent to the tensile strength of S355 are used as welding consumables. For unprotected use care must be taken that the welded joint is also weather resistant. This is possible by using welding consumables matching the base material.A588 A588 Steel A588 Steel Plate Kloeckner Metals A588 welds similar to low carbon steels like ASTM A36 and ASTM A572. Due to A588s specific coloring, you will need to consider color matching when welding. Advantages/Disadvantages. The biggest advantage to A588 is its atmospheric corrosion resistance for which it was specially formulated.
