Underwater Cutting And Welding Manual

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 manual that incorporates state of the art equipment and tried and proven underwater cutting and welding 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 cutting 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.

Versatility, speed and low cost make wet-stick welding an attractive method for use in underwater repair and construction. This training manual and reference book contains step-by-step procedures for performing basic manual metal arc welding operations together with information on welding equipment, consumables and safety. Exercises are included.

This purpose of this course is to teach safe Oxy-Arc Underwater Burning Techniques. This course will provide industry-accepted best practices for meeting and exceed the requirements of industry associations and standards listed below. Burning is a tool which can be used safely; however, the user must have a clear understanding of the concepts and procedures to be taught in this class. This Training meets or exceeds: 1. IMCA D003 Guidelines for Oxy-Arc Cutting 2. ADCI Rev. 6.2, 5.31 Welding and Burning 3. ANSI/ACDE 01-2009 Standards, 28.0 Introduction To Underwater Burning and Welding 4. Recommended Practices of the following manufacturers: a. Oxylance b. BROCO-Rankin c. ArcAir d. Fire Wire Marine e. Specialty Weld: Swordfish Arc Cutting Electrode

The proceedings of an international seminar organised by TWI in conjunction with the Paton Welding Institute, Ukraine and held at TWI Middlesbrough in April 1997. The delegates examined recent theoretical and practical developments of the materials, equipment and processes involved.

This manual contains step-by-step procedures for performing successful underwater wet-stick welding operations. It will aid all those seeking to better understand the parameters involved in wet welding, but it also includes many other relevant sections all closely connected to welding. It also shows how to achieve the best results with any particular technique when carrying out wet welding. Practical exercises on the three basic techniques are also given at the end of the manual.
