Suhner Power Tools, Abrasives Improve Workflow for Royal Welding

Royal produces units to withstand extreme pressures, high vacuum processing and high and low temperatures for hazardous chemical extraction processing, providing customers with often unique, application-specific designs.

Royal Welding & Fabricating (Fullerton, California) prides itself on two basic tenets. As General Manager Wallace Cook explains, “We specialize in stainless steel and aluminum welding, often with mirror finish, plus we can offer complete turnkey operation for the highly challenging jobs, with design, engineering, most component production, all assembly, welding, grinding, fine finish and full testing capability, all in-house. That means customers can bring their jobs to us with complete confidence and know they’ll get quick response, should any changes be required.” Cook also takes pride in having originated the company’s slogan, “Where Quality is King.” In business over 50 years, this Los Angeles-area shop produces a wide assortment of tanks, mixers, chambers and extractors for myriad industrial, medical and commercial uses. All the welders here are ASME Certified and Royal conforms to all necessary standards for the aerospace, nuclear and other high-precision markets. 

Royal produces units to withstand extreme pressures, high vacuum processing and high and low temperatures for hazardous chemical extraction processing, providing customers with often unique, application-specific designs. The company’s dimpled plate designs, for example, are renowned for their superior heat dissipation and cost savings, as an alternative to partial or full metal jacket heat exchangers. Royal also fabricates a variety of custom tube & shell heat exchangers, centrifugal pump vessels, agitators, autoclaves, hydroclaves, high-volume cooking kettles, high-pressure tanks for reverse osmosis, extreme environment vessels and vacuum chambers to all applicable ASME, TEMA and 3A standards. Units produced here are in use for water conditioning on the space station.  

All work here begins in the design department, where the latest CAD technology produces designs for the various machine shop operations located in-house at Royal.  These include metal bending, conventional chip-cutting machine tool work, forming and fabrication, final assembly and performance testing plus a key area of this shop, the grinding and finishing department.  Every weld and surface finishing job at Royal is done to the highest quality specifications and the abrasives used must match the materials, job requirements and appearance standards set by the customer and by Royal. 

A key partner in this latter department is the Abrasive Power Tool Division of Suhner, based in Rome, Georgia and part of the Swiss company, Suhner AG. This supplier’s local representative is Regional Sales Manager Gary Mergeanian, who has served Royal for over 25 years.  As he observes, “Few customers present me with the daily challenges I get from Royal, but these are the moments that make doing business so rewarding. When I can bring a solution to the job at hand, whether it’s a special abrasive pad or a full power tool assembly, that’s exciting.  Best of all, the satisfaction of the Royal welding and finishing operator teams is my goal and getting it is very important to me.”

One of the newer Suhner developments on the job every day at Royal is the Roto family of products, where the motor drive, flex shaft and handheld adapter unit are integrated into a powerful and flexible tool package. By separating the weight of the motor and mechanical drive components from the hand tool, plus incorporating highly flexible adapters into the handheld unit, Suhner allows the operators much greater flexibility in performing their work. As Wallace Cook comments, “Our operators have less fatigue and greater freedom of movement with these units, which allow long periods of work in tight spaces or inside large containment vessels. That’s a real plus for the guys in the shop. And Suhner, through Gary Mergeanian, is always bringing us new and better ways to grind welds and finish surfaces on stainless and aluminum.”

Belt and pad abrasive work can be done on the same tool, using the Roto family, which further speeds the work at Royal.  The shop recently built its own polishing machine setup for internal tank head polishing, using a variety of Suhner components. 

As further evidence of the performance his shop realizes from Suhner tools and abrasives, Cook notes he’s often recommended this supplier to other companies, even some competitors, he muses. 

Shop Supervisor at Royal Ricardo Guerrero agrees. “The tools are very good, easy to handle and the guys don’t get worn out. We can do faster finishing with less abrasive and that means money saved.”
