Welding Transformer: The Heart of the Machine
Spot welding machine transformers have no moving parts and often run for decades if not abused. Abuse includes overheating due to excessive duty cycle operation, lack of adequate water flow, and internal water saturation due to water leaks or condensation.
If your welding transformer is water-cooled, check to make sure the small diameter internal copper water cooling tubes are not clogged, crushed, or leaking. If the machine has been run on city or well water, minerals can accumulate over the years just like excessive cholesterol clogs our arteries. Chemicals are available to clear clogs in water cooling lines, but sometimes the transformer needs to be disassembled so the water lines can be replaced.
Shorted-out spot welding machine transformers can be rebuilt, but it’s best to send them to a specialist rather than your local electric motor repair shop.

Did You Know?
Spot welds not only make a vehicle safer, but can also help in reducing rattles and road noises. An average mid-sized car has 5,000 spot welds.

I visited my dentist the other day to have a filling repaired.
It was actually a small cavity in the tooth that already contained a gold filling. (The gold filling was done years before the sky-rocketing cost of gold!).
All went well as I tried to converse and endure with their fingers and tools in my mouth.
Upon completion, the dentist warned me that I may feel a “poke” around that tooth for a few days.
It wasn’t due to sensitivity or a bad fill job, but to the galvanic shock.
I hadn’t realized that when agreeing to use a silver-based filling for the new spot, I had set myself up.
The gold and silver create an actual electric shock between them of direct current.
The galvanic shock does subside after a few days and, in truth, it wasn’t as jolting as I had been told it might be.
A word of caution: When working with dissimilar metals, in welding or in teeth, extra caution should be taken.

The Annual Meeting Edition
Volume 4- Issue 1
Message From The Chair
Dear RWMA Members,
Welcome to the beginning of another new year in the RWMA!
Thanks to each of you who attended and contributed at the past Annual Meeting and participated in the renewal of the Fall Meeting. The feedback from participants indicated that all of us gained something of value to help our businesses compete and improve in this continually evolving and dynamic global economy.
The coming year will prove to be another great opportunity for you to learn more (and teach) about the resistance welding process and its vital role in the economy and our livelihoods. The focus of our effort as a volunteer industry organization is to advance resistance welding technology, broaden its use, and promote its economic benefits.
We will accomplish this by:
1) Promoting resistance welding and maintaining a presence at trade shows and in trade journals around the world in conjunction with our liaisons at AWS.
2) Improving our stewardship of the Emmet A. Craig Resistance Welding School held in conjunction with FABTECH each year.
3) Participating in the AWS sponsored work in CCRW, J1 and C1 committees.
4) Conducting content-rich meetings with learning and networking opportunities for our members.
For those of you who are new to the industry or RWMA, the real mainstay program of the RWMA has been and will continue to be the RWMA Welding School. Thanks again to all who volunteer their valuable time and introduce so many new people to the process of resistance welding each year. By introducing thousands of people to the RW process over the decades, the school provides a vital link that connects us all in the industry.
Speaking of learning, Dr. Jerry Gould of the Edison Welding Institute will be giving the 2013 Annual Meeting’s keynote address. Dr. Gould brings decades of experience in the industry and published over 120 technical papers on various aspects of resistance welding, holds six patents and co-authored 20 EWI Cooperative Research Reports.
I encourage all members to join Dr. Gould and register for the meeting on February 21-23 at Saddlebrook Resort just north of Tampa, Florida. This year's RWMA speaker and WEMCO speakers Mr. John Howell, Mr. Dave Mizerowski and Dr. Martin Greitmann along with the economist Alan Beaulieu will provide critical and timely information to our members and, of course, the weather will always tempt Northerners and Southerners alike to journey south. It's a meeting packed with great speakers and lots of great networking opportunities!
I would like to thank Wade Burnette of NSRW for his steady hand at the helm of RWMA for the past two years.
He attended every meeting and helped tremendously with the successful transition of our new staff at RWMA.
Lastly, I'd like to thank you all for allowing me to represent you as the 2013 RWMA Chair. It is a privilege to be part of the resistance welding industry in this way.
We need your input and ideas to keep RWMA healthy and moving forward so please share them with me. Bring those ideas, issues and/or concerns to Committee Management Specialist, Keila DeMoraes at email@example.com.
See you at Saddlebrook!
RWMA 2013/2014 Committee Chair

J1 Quarterly Report
J1 Committee on Resistance Welding Equipment
The J1 Committee on Resistance Welding Equipment is responsible for the preparation of standards related to resistance welding consumables, components, and machinery
The J1 Committee Report
The AWS J1 Committee on Resistance Welding Equipment is chaired by Don Sorenson from Entron Controls. The committee is in the final stages of balloting the J1.1 Specification for Resistance Welding Controls document through the committee publication process.
The committee is also in the initial document review stage of the J1.2 Guide to Maintenance of Resistance Welding Machines document, and has begun the preparation of a draft Roadmap for US Resistance Welding Electrode Standards. The intent of the Roadmap is to provide an overview of the US standards such as RWMA Bulletin 16 - Section 8, Resistance Welding Equipment Standards – Electrodes, AWS D8.6, Specification for Automotive Resistance Spot Welding Electrodes, plus the applicable international standards. The objective is to establish a prioritized plan to address the market needs for electrode related standards and the interests of the participants.
The draft and a solicitation for participation have been distributed amongst the J1 committee and RWMA membership, and a meeting to solicit further assistance on the document will be held at the 2013 RWMA Annual Meeting in Wesley Chapel, FL. A new work item pertaining to a series of Resistance Welding Fact Sheets is being considered for J1 committee activity as the Fact Sheets would disseminate useful and practical information to users of the resistance welding process. At this time there is a four-page draft Grounding Reactor Fact Sheet based on information culled from RWMA Bulletin 16.
Click on the links below for more information:
Before an AWS permission to prepare form is solicited, it is desirable to have additional one to four page drafts to demonstrate the concept and its merits. J1 recently published the Resistance Welding Pocket Handbook (RWPH: 2011), available for purchase from the AWS publications website and catalog for $20 list price or $15 for members.
The next meeting of the J1 Committee will likely take place during the week of 4/29/13 in Livonia MI. Individuals who are interested in participating in the development of the above resistance welding equipment standards can obtain additional information on the J1 Committee activities by contacting the J1 Committee Secretary, Efram Abrams by phone at 800-443-9353, ext. 307, or email email@example.com .
