Drawing a bead on the cost of welding.Welders with the ability to make quality welds for all types of piping are highly sought for mechanical construction projects nationwide. But great welding skills take time and education to develop, and welders who will make the various types of welds must all be tested and certified for the work they will do-creating additional expense for the end-user. Fortunately, there is an organization called the National Certified Pipe Welding Bureau (NCPWB NCPWB National Certified Pipe Welding Bureau ) that streamlines that process, minimizing costs and maximizing quality for all involved. They've been providing this service to their members for more than 50 years.
The National Certified Pipe Welding Bureau, associated with the Mechanical Contractor's Association of America (MCAA MCAA Mason Contractors Association of America (Oakbrook Terrace, Illinois)
MCAA Messenger Courier Association of the Americas
MCAA Marine Corps Aviation Association
MCAA Mechanical Contractors Association of America, Inc. ), oversees more than 600 Contractor members in 45 chapters. NCPWB members jointly develop welding procedures as well as lay down quality control procedures which allow contractors to hire welders from a common pool. The bureau can easily link contractors and welders with appropriate credentials to construction projects that have highly specific needs. "The owners save money because our welder pool is highly diversified and our quality assurance umbrella eliminates unnecessary retests," said Daniel R. Bulley, Executive Vice President, Certified Welding Bureau (CWB CWB Canadian Wheat Board

The NCPWB members represent a pool of more than 11,000 union pipe fitter welders across the nation. In recent years the NCPWB has teamed up with the United Association (UA), which runs a similar program. Since both were running programs for union pipe fitter welders, it was only natural for them to get together. To achieve further savings, many tests are given jointly, with both NCPWB contractors and UA quality-assurance people attending. The UA also has an extensive quality-assurance program developed with Hartford Insurance.

They provide a means, recognized by the national codes and standards, to make quality welding available at an economical price. Bureau members gain a collective working advantage with the following benefits:
WPSs: The NCPWB has more than 100 WPSs that have been developed and qualified in accordance with ASME code requirements. They include procedures for welding carbon, low-alloy and stainless steels stainless steel: see steel.
Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. , aluminum alloys, nickel alloys and titanium using all the common are welding processes This is a list of welding processes, separated into their respective categories.

These WPSs, which have been reviewed and found acceptable by Hartford Steam Boiler Insurance Boiler insurance is a type of property insurance that pays accidental losses to machinery and equipment. Although it is called boiler insurance it can actually cover just about any device that uses, transmits or generates mechanical or electrical power; of course certain exclusions , may be used on piping by member contractors without additional qualification.
Walter Sperko, P.E., NCPWB Technical Consultant, observed, "These WPSs would cost a contractor in excess of $500,000 to duplicate, and they are available for use without the three-to four-week lead time normally needed if a contractor were to qualify them on his own." The ready availability of these WPSs is a clear and significant benefit to the contractor and the customer.
Qualification of Welders and Welder Interchange: ASME piping codes provide for interchange of welders between NCPWB contractors. To assist in this interchange, the NCPWB has established a national welder database. This database contains the names of more than 11,000 welders and it shows the date, location and processes for which welders are qualified. The savings achieved are significant when a welder can go to work immediately at a new jobsite without time-consuming and costly re-qualification.
UA Welder Certification Welder certification, (also known as welder qualification) are specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The tests consist of many variables, including the specific welding process, type of metal, thickness, joint design, Program: The NCPWB and the UA have teamed up to make the welder qualification process more cost-effective to the construction user. Welders are tested at the UA's authorized test facilities under the supervision of an NCPWB contractor representative and a UA Authorized Test Representative (ATR ATR Achilles tendon reflex, see Ankle reflex ). An independent testing laboratory x-rays or mechanically tests each welder's test coupon, and the results determine which welders are qualified. Test records are completed by the contractor and the ATR and made available to contractors through the NCPWB. Once qualified, the welder must weld with each process once every six months to remain qualified. The NCPWB and UA maintain these records. Accurate records of a welder's history must be kept-otherwise, every time a welder moved to a new employer, he or she would need to retest re·test

"The primary savings are a collection of WPSs 'ready to use' and a pool of welders who have been trained and qualified to Code," said Mr. Sperko. "All that saves the ultimate customer money and gives the UA contractor significant benefits over non-union competition."
What kind of savings can a builder expect, in addition to the savings on procedures? "When you figure $250 per test, plus hall a day's pay for the welder, the cost to qualify a welder is about $500. So for a ten-welder job, a savings of $5,000 is realized right off the bat. When you figure we have 10,000 certified welders in the local, the potential savings to the industry is more than $5,000,000," said Mr. Bulley. "There are many jobs where you might use 100 or more welders, so there is potential to save a great deal of money."
The process of tracking and maintaining the welding labor pool is not an easy one, but NCPWB chapters handle the task efficiently.

Having a large pool of highly trained and Code-qualified welders to assure quality construction is just one of many promises that MCAA affiliates make regarding their commitment to providing state-of-the-art service. For more information on MCA MCA
