WELDING AND CUTTING OF PIPE & TUBING

November 4, 2010
Atlanta, Ga.
Facility: Georgia Word Congress Center (FABTECH)
Chair: Robert Irving; Co-chair: Ian Harris

Highlighting the conference on pipe and tubing will be Ian D. Harris from Edison Welding Institute who will discuss three processes - DeepTIG, narrow groove tandem GMAW-P, and hybrid laser welding. From north of the border, Robert J. Pistor from Liburdi Automation will discuss the role of orbital welding in the new combined-cycle gas turbine power plants in Canada. And Eric Carlson of CRC-Evans will talk about the past and present in automoatic pipeline welding.

From the standpoint of cutting, Jeff Bennett of Vernon Tool will discuss the benefits and considerations via automating pipe and tube cutting and profiling processes. Joe Sorvaag of ESAB will also be on hand with a comparison of thermal cutting options.

Arc welding processes continue to develop along with other welding and joining processes. For tube and pipe welding, applications range from thin-walled titanium tubing to thick walled low alloy steels for nuclear, offshore, pressure vessel, and aerospace applications. This presentation will cover innovative developments and solutions using EWI Deep TIG powder and wire, narrow groove Tandem GMAW-P (NG TGMAW-P), and hybrid laser arc welding (HLAW) processes.   

The Growing Demand for Power Piping Welding, a Canadian Case Study
9:40 AM - 10:15 AM
Robert J. Pistor, P. Eng, Principal Engineer, Managing Director, Liburdi Automation, Dundas, Ontario

Until recently the demand for new power plant construction in Canada has been relatively low. Power imports from the United States have been able to meet peak demands leaving new construction plans on hold. With the de-commissioning of coal fired plants in Ontario, several new combined cycle gas turbine power plants are under construction. One such plant is Sithe Global’s Goreway station located minutes north of the Toronto Airport. This is the first major power plant to be built in 25 years in Ontario. This paper reports on the challenges faced in welding the high energy power piping for the Heat Recovery Steam Generator (HRSG), the training of local craft and provides perspective for future projects.

MORNING BREAK - 10:10 AM - 10:25 AM

Automating Pipe and Tube Cutting and Profiling Processes: Benefits and Considerations
10:30 AM - 11:05 AM
Jeff Bennett, Managing Director, Vernon Tool Co., Oceanside, Calif.

Conventional thought leads many manufacturers to the conclusion that investing in automated machinery is only justified in high sequences can be repeated over hundreds and thousands of parts. To counter this notion, current and emerging technologies and developments will be presented to illustrate the benefits of automating pipe/tube cutting in all environments, including low volume / high mix operations. Additionally, several key factors will be discussed that play an important role in designing and selecting the optimal automation solution. These considerations include: material handling, software, programming, CAD/CAM functionality and work cell layout.

Using Orbital GMAW/FCAW in a Fab Shop
11:00 AM - 11:35 AM
John Emmerson, President, Magnatech LLC, East Granby, Conn.        

Orbital welding can increase productivity in a fabrication shop, even in situations where the pipe is being rotated. Several case studies will be discussed. With the recent introduction of a new model, the root pass can also be done by machine. Productivity increases by eliminating the fatigue factor of the welder, which is significant, even when welding in the 1G position. Orbital welding also provides a better work environment for the employee: lessening exposure to fumes, and eliminating the hand held torch, and potential for repetitive motion injuries.
   
LUNCH (PROVIDED) & EXHIBIT DISPLAY - 11:35 AM - 1:35 PM

Automatic Pipeline Welding
1:35 PM - 2:10 PM
Eric Carlson, Welding Engineer. CRC-Evans Automatic Welding, Houston, Tex.
 
Founded in 1933, CRC-Evans Pipeline International supplies the pipeline construction industry with the infrastructure and resources to support pipeline contractors worldwide. Since the first mechanized welding process was introduced in 1969, CRC-Evans Automatic Welding systems have been designed, tested, used and continuously upgraded for more than 40 years. The focus of this presentation will be general pipeline construction, the history of automatic welding systems, and the advantages of automatic welding technology from its first introduction to present.

Friction Welding of Pipe and Tubing
2:10 PM - 2:45 PM
Daniel C. Adams, Vice President of Sales and Business Development, Manufacturing Technology, Inc., South Bend, Ind.
 
There are several popular Friction Welding techniques for Pipe and Tubing applications. The most popular of these is Rotary Friction Welding, but there is increasing interest in Friction Stir Welding. Many of these applications will be discussed to show how Friction Welding has proven to be a high quality and cost effective means of joining.

AFTERNOON BREAK - 2:45 PM - 3:00 PM

A Comparison of Thermal Cutting Options
3:00 PM - 3:35 PM
Joe Sorvaag, Project Development Manager, ESAB Cutting Systems, Florence, S.C.
 
The objective of the discussion is to provide a comparative exploration of simple to complex plasma and oxyfuel systems in order to rationalize the relative benefit and returns of each process. Included in the discussion will be the comparative cost and output results benefit of single gas air plasma, shielded gas plasma, water injection plasma, and oxyfuel technology, as well as levels of automation integration available for each process. The output results benefit comparison will include the following cutting attributes. Applicability or advantage of the cutting process for different material types (carbon, stainless steel and aluminum).Resultant edge quality for welding. The capability for each process to produce compound bevel edges for weld preparation.The achievable accuracy for the finished cut from each process.

Explosion Welding for Dissimilar Metal Pipe Transitions
3:35 PM - 4:10 PM
Michael Blakely, Director of Market Development, Dynamic Materials Corporation, Sugar Land, Tex.

Explosion welding (EXW) is used in many industries to join similar and dissimilar metals. One use of explosion welded materials is to create transitions between materials in critical tube and piping applications.  Combinations of material include aluminum to stainless steel and copper nickel to aluminum. This presentation will discuss how explosion welded plates are prepared and subsequently turned into transition joints for piping.  A few example applications of these transition joints will also be covered.
