BY CHANGE A 15 Sep 1998 Changesaffectfrontmatter,Chapter2andAppendixD KLB S0300-BB-MAN-010 FOREWORD Ship Salvage, Harbor Clearance and Wreck Removal oftentimes require extensive underwater cutting and welding. The lack of recent fleet experience in these areas dictates the need for a man- ual that incorporates state of the art equipment and tried and proven underwater cutting and weld- ing techniques. The knowledge contained in this manual is a collection of fleet and commercial experience. It has been reviewed by technical experts with extensive salvage and underwater cut- ting and welding experience. This revision of the Underwater Cutting and Welding Manual has been prepared to provide the most current information on equipment and procedures available. All of the equipment covered may not be found on the Diving Equipment Authorized for Navy Use (ANU) list (NAVSEAINST 10560.2), but is included in this manual as an aid to the salvor who finds himself in a “must get the job done” situation. Further guidance can be found in Appendix E. Due to limited time allocation, there is a lack of realistic underwater cutting and welding training in the Navy’s diving schools. Students are given only the basics in school and thereafter must practice to become proficient and gain the experience necessary to become “qualified underwater cutters and welders.” I therefore charge all diving officers, master divers and diving supervisors to establish or maintain existing training programs for underwater cutting and welding. Practice, practice, practice. C.A.

This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces. Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, under water and in outer space. Regardless of location, welding remains dangerous, and precautions are taken to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light.

  • Sizing the Primary Power System for Resistance Welders
    SIZING THE PRIMARY POWER SYSTEM FOR RESISTANCE WELDERS By Jack Farrow, May, 2004 WELDING TECHNOLOGY CORPORATION ABSTRACT Information on how to select the correct size of substation transformer and 480V bus to power one to one thousand resistance welding machines is presented. Powerline voltage drop, light flicker, power factor correction and harmonic currents are discussed. Strategies to allow more welders to operate on a given power system are explained. Techniques to improve the efficiency of the power system and reliability of the welding process are identified. Consideration is given to selecting the correct sizes and types of fuses. Useful reference material will be available to attendees. INTRODUCTION Because resistance welders draw large currents on an intermittent basis, they present special problems to the primary power system in a manufacturing plant. This paper answers the following questions related to these problems. 1. What size does the three-phase power system need to be to support the number of welders I have? 2. How is a welder power bus different from other power buses? 3. What can be done to improve power system efficiency and capacity utilization? 4. What is the proper size and type of fuse to use? For the purposes of discussion in this paper, spotwelding of steel sheet of thickness between 0.5 and 3 mm. is assumed. The power system supplying the welders is 480VAC, 60 HZ, three-phase. In general, the discussion is centered around standards and practices most commonly used in the North American automobile industry. I. What size does the three-phase power system need to be to support the number of welders I have? A typical resistance spotwelder draws between 100,000 and 200,000 watts when welding! To avoid problems of cold welds due to insufficient power, the 480 VAC power system must be capable of supplying this power with less than 10% voltage drop.

  • Aluminum Systems Guide
    Aluminum Systems Guide 1 The Miller ® Difference Aluminum isn’t easy to weld: It has a lower relative melting point than other metals yet requires heat to ensure proper puddle formation. Cleanliness is critical. It is more sensitive to heat input and distortion. Aluminum wire is also softer and more difficult to feed through a wire feeder and gun than other metals. High-quality welds are attainable, despite these challenges, through specialized welding systems and filler metals. Whether your shop uses aluminum exclusively or on a project- by-project basis, Miller has the MIG and TIG solutions for every application. Our complete line of easy-to-use welding equipment offers unsurpassed performance, superior puddle control and appearance, and consistent arc quality — resulting in code quality welds every time you strike an arc. Miller® aluminum MIG systems rely on advanced technology that actually simplifies welding while providing the smoothest, most consistent aluminum wire feeding on the market. Miller aluminum TIG systems provide superior arc performance and control that provide optimum quality, performance and aesthetics. Miller equipment makes aluminum welding easy, efficient and profitable — helping you improve weld quality, boost operator confidence, and keep ahead of the competition.

  • An Experimental Investigation of Mechanical Properties of Al 6106 T6 Alloy Joined by Friction Stir Welding and TIG Welding
    International Journal of Innovations in Engineering and Technology (IJIET) An experimental investigation of mechanical properties of Al 6106 t6 alloy joined by Friction Stir Welding and TIG welding Sushil Kumar Kamat M.Tech Scholar, Om Institute of Technology & Management, Hisar Ajay Kumar Assistant Professor, Om Institute of Technology & Management, Hisar Abstract : FSW is a solid state new joining process that is presently attracting considerable interest. In this process the two pieces of metal are mechanically intermixes at the place of join, then often them so that the metal can be fused using mechanical pressure. Some aluminum alloys can be welded with electrical resistance techniques, TIG, MIG provided that an extensive surface preparation and the oxide formation is controlled. On the contrary, FSW can be used with success to weld most of Al alloys considering that superficial oxide generation is not deterrent for the process and no particular cleaning operations are needed before welding. friction stir welding was mainly developed for aluminum alloys. Al 6101 T6 aluminum alloy has been selected to perform FSW. Al 6101 alloy has been welded with FSW and TIG welding techniques. It has been found that tensile strength and hardness of FSW is more than that of TIG welding. The mechanical properties of both welding specimen has been compared and with base metal strength. Microstructure has also been examined. Keywords : FSW, TIG, Aluminum alloy I. INTRODUCTION Welding is a fabrication process used to join materials, usually metals or thermoplastics, together. During welding, the pieces to be joined ( the workpieces ) are melted at the joining interface and usually a filler material is added to form a pool of molten material ( the weld pool ) that solidifies to become a strong joint.
