309 welding rods are mostly used to weld 300 series to carbon steel. They are very handy to have around because they make really pretty welds on carbon steel also and prevent porosity when welding hot rolled steel. 321 and 347 stainless is very similar in weldability to 304. the main difference is a small amount of titanium, columbium, or tantalum.

Production process:CokingIron-makingSteel-makingRolling. Hot Rolled Steel vs. Cold Rolled Steel Swanton WeldingHot rolled steel is usually cheaper to produce than cold rolled steel. This is mainly because the hot rolled steel is more malleable, hence you dont need heavier rollers or more production cycles to form a product. However, because its shape can shift after the process is over hot rolled steel can lead to additional reshaping expenditures
This code covers the requirements associated with welding sheet steel having a minimum specified yield point no greater than 80 ksi [550 MPa]. The code requirements cover any welded joint made from the commonly used structural quality low-carbon hot rolled and cold rolled sheet and strip steel with or without zinc coating (galvanized). Clause 1 Submerged arc welding pipe, SAW pipes, SAW pipe SAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction. Welding Cold-Formed SteelContractor. In cold-formed steel construction, welding is a viable connection method. Prefabrication of trusses, panelization of walls, and hardware components are all ideal applications where welding may be the preferred joining method. Although arc welding or resistance welding may be used to connect thin sheet steel, in building construction
Mar 30, 2020 · Made an S shape tool rest for a wood lathe, in a mini paint can forge from some 5/8 rod. Not enough material for the post.
