This Section is applicable only to piping for installation on vessels to be built in accordance with the Rules for Building and Classing Steel Vessels. ii ABS RULE REQUIREMENTS FOR MATERIALS AND WELDING . 2002 PART 2 Foreword For the 1996 edition, the “Rules for Building and Classing Steel Vessels – Part 2: Materials and Welding” was re-titled “Rule Requirements for Materials and Welding – Part 2.” The purpose of this generic title was to emphasize the common applicability of the material and welding requirements in “Part 2” to ABS-classed vessels, other marine structures and their associated machinery, and thereby make “Part 2” more readily a common “Part” of the various ABS Rules and Guides, as appropriate. Accordingly, the subject booklet, Rule Requirements for Materials and Welding – Part 2, is to be considered, for example, as being applicable and comprising a “Part” of the following ABS Rules and Guides: - Rules for Building and Classing Steel Vessels. - Rules for Building and Classing Steel Vessels Under 90 Meters (295 Feet) in Length - Rules for Building and Classing Mobile Offshore Drilling Units - Guide for Building and Classing High Speed Craft For the 2002 edition, a new Section 4, “Piping” has been added to Part 2, Chapter 4, “Welding and Fabrication”. This new Section is applicable only to piping for installation on vessels to be built in accordance with the Rules for Building and Classing Steel Vessels.

These types of weld are very interesting for junctions of Al-alloys parts in the transportation field to promote the lightweight of a large scale chassis. The weld joints were characterized through various metallurgical methods including optical microscopy and hardness measurements to assess their microstructure and to individuate the nature of the intermetallics, their morphology, and distribution. The results allowed for the evaluation of the discrepancies between the welding technologies (MIG, CMT, fiber laser) on different aluminum alloys that represent an exhaustive range of possible joints of a frame. For this reason, both simple bar samples and real junctions of a prototype frame of a sports car were studied and, compared where possible. The study demonstrated the higher quality of innovative CMT and fiber laser-MIG hybrid welding than traditional MIG and the comparison between casting and extrusion techniques provide some inputs for future developments in the automotive field.

Aluminium has properties that are favourable for structural engineering, including good strength-to-weight ratio, corrosion resistance and machinability. It can be easily recycled saving energy used in smelting as compared to steel. Its alloys can have ultimate tensile strength of up to 750 MPa, which is comparable to steel.

  • Magnetically Impelled Arc Butt (MIAB) Welding of Chrome Plated Steel
    MAGNETICALLY IMPELLED ARC BUTT (MIAB) WELDING OF CHROMIUM- PLATED STEEL TUBULAR COMPONENTS UTILIZING ARC VOLTAGE MONITORING TECHNIQUES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By David H. Phillips, M.S.W.E ***** The Ohio State University 2008 Dissertation Committee: Professor Charley Albright, Advisor Approved by Professor Dave Dickinson _________________________________ Professor John Lippold Advisor Welding Engineering Graduate Program ABSTRACT Magnetically Impelled Arc Butt (MIAB) welding is a forge welding technique which generates uniform heating at the joint through rapid rotation of an arc. This rotation results from forces imposed on the arc by an external magnetic field. MIAB welding is used extensively in Europe, but seldom utilized in the United States. The MIAB equipment is robust and relatively simple in design, and requires low upset pressures compared to processes like Friction welding. In the automotive industry, tubular construction offers many advantages due to the rigidity, light weight, and materials savings that tubes provide. In the case of automotive suspension components, tubes may be chromium-plated on the ID to reduce the erosive effects of a special damping fluid. Welding these tubes using the MIAB welding process offers unique technical challenges, but with potential for significant cost reduction vs. other welding options such as Friction welding. Based on published literature, this research project represented the first attempt to MIAB weld chromium-plated steel tubes, and to utilize voltage monitoring techniques to assess weld quality. ii Optical and SEM microscopy, tensile testing, and an ID bend test technique were all used to assess the integrity of the MIAB weldments.

  • STEEL for FORGE WELDING F Ra N K N
    No. 1853 STEEL FOR FORGE WELDING F ra n k N . S peller, P ittsburgh, P a. Member of the Society In this paper the principal factors — method of manufacture, chemical composition, fluxing quality, susceptibility to heat and welding temperature — affecting the welding quality of steel are discussed and the average results of 80 tests made on forge welds of hammer-welded pipe are compared with the original material. In addition it is stated that tests have demonstrated that both steel not over 0.16 per cent carbon and minimum tensile strength of 47fi00 lb. per sq. in. and that not over 0S0 per cent carbon and minimum* tensile strength of 62,000 lb. per sq. in., are satisfactory for forge welding of pipe lines, penstocks, tank-car work and similar construction but that the former is best adapfed for welded parts of boilers and pressure vessels. In conclusion the writer believes that the most important consideration to pro­ duce uniformly good results in the forge welding of steel, is suitable ma­ terial, weU^trained operators and adequate facilities for the control of operations. An appendix is devoted to a presentation of the Tentative Specifica­ tions for Steel Plates for Forge Welding of the American Society for Testing Materials as revised in 1921. HE welding quality of steel, and the strength and reliability of such welds, depend on a number of factors, which include prin­ Tcipally: method of manufacture, composition of the metal, suscepti­ bility to heat, fluxing quality, the mechanical appliances for hand­ ling and controlling the work, and the skill of the operator.

  • Welding of Aluminum Alloys
    4 Welding of Aluminum Alloys R.R. Ambriz and V. Mayagoitia Instituto Politécnico Nacional CIITEC-IPN, Cerrada de Cecati S/N Col. Sta. Catarina C.P. 02250, Azcapotzalco, DF, México 1. Introduction Welding processes are essential for the manufacture of a wide variety of products, such as: frames, pressure vessels, automotive components and any product which have to be produced by welding. However, welding operations are generally expensive, require a considerable investment of time and they have to establish the appropriate welding conditions, in order to obtain an appropriate performance of the welded joint. There are a lot of welding processes, which are employed as a function of the material, the geometric characteristics of the materials, the grade of sanity desired and the application type (manual, semi-automatic or automatic). The following describes some of the most widely used welding process for aluminum alloys. 1.1 Shielded metal arc welding (SMAW) This is a welding process that melts and joins metals by means of heat. The heat is produced by an electric arc generated by the electrode and the materials. The stability of the arc is obtained by means of a distance between the electrode and the material, named stick welding. Figure 1 shows a schematic representation of the process. The electrode-holder is connected to one terminal of the power source by a welding cable. A second cable is connected to the other terminal, as is presented in Figure 1a. Depending on the connection, is possible to obtain a direct polarity (Direct Current Electrode Negative, DCEN) or reverse polarity (Direct Current Electrode Positive, DCEP).

Marya Date of Examination: 23 October 2008 Abstract Abstract The objective of the present thesis is to make advancements in understanding solidification crack formation in aluminum welds, by investigating in particular the aluminum 6060/4043 system. Alloy 6060 is typical of a family of Al-Mg-Si extrusion alloys, which are considered weldable only when using an appropriate filler alloy such as 4043 (Al-5Si). The effect of 4043 filler dilution (i.e. weld metal silicon content) on cracking sensitivity and solidification path of Alloy 6060 welds are investigated.
