The Welding Handbook for Maritime Welders.pdf
Taken from Solutions: Problem Steel: Among the low alloy steels, there is also a large group of special steels with complicated chemical composition. These include spring steel, vanadium steel, high speed steel, tool steel, etc. All these steel types are difficult to weld. In many cases the steel has been hardened by annealing, and welding can destroy the hardening.
In principle, all these steels can be welded with matching ferritic consumables with the aid of preheating and postweld heat treatment to avoid hydrogen cracking in the heat affected zone (HAZ).
In the case of repair welding, it is, however, often not possible to preheat or to perform any postweld heat treatment.
So, in this case, welding with austenitic stainless or nickel-based consumables is considered to be one of the best methods. The risk of cracking is reduced by the higher solubility of hydrogen and the greater ductility of the weld metal.
There are so many types of low alloy steel on the market today that even specialists have difficulty in keeping track of the entire range. Numerous types of special alloys not classified under existing standards, are marketed by the steel works. Most types can be welded satisfactorily with Unitor Tensile having a tensile strength of 850 N/mm2. This electrode may be used both for joining and for building-up work
Titanium - Design and Fabrication Handbook for Industrial Applications.pdf
Titanium offers an excellent combination of mechanical properties and corrosion resistance. These features, coupled with availability of product forms and ease of fabrication, have led to extensive use of titanium and its alloys in chemical process equipment. Titanium is now a standard material of construction for many chemical processes and equipment, and systems are being assembled by a variety of fabricators on a routine basis for use in many other industries.
KOBELCO Welding Handbook - Welding Consumables and Processes.pdf
This welding handbook was issued by Kobe Steel Ltd., involving new group brand names and the corresponding products such as FamiliARC, TrustARC, and PremiARC. This handbook also informs various tips and tricks to get a better welding result by maintaining the welding parameter to prevent welding defects such as hot cracking, selecting proper wires, not to cause the deformations of wires and more.
Gas Metal Arc Welding of Stainless Steel.pdf
The purpose of this manual is to make you a better welder by increasing your knowledge of how the GMAW process works.
A more knowledgeable welder can be more productive by working smarter, not harder. Figure 1 shows why your company is interested in educating you in welding stainless steel. Your labor and overhead account for about 80% of the cost of depositing weld metal. Any knowledge you gain from this course not only helps you, but also helps to make your company more competitive in a very tough marketplace.
Miller - Handbook for Resistance Spot Welding.pdf
Resistance welding is accomplished when current is caused to flow through electrode tips and the separate pieces of metal to be joined. The resistance of the base metal to electrical current flow causes localized heating in the joint, and the weld is made.
