The SWR was designed specifically for automated pipe welding. <\/p>\n
For Joe White Tank in Fort Worth, Texas, increased demand for construction projectsand more competitive bidding for the pipe fabrication jobs within those projectsrecently presented a new challenge. <\/p>\n
The company has been in the welding industry since 1942, specializing in fabricating custom tanks, pressure vessels for industrial and ammonia refrigeration, and piping for commercial and industrial construction. It has built a reputation for quality work while consistently delivering products faster than typical market lead times. <\/p>\n
That standard recently got put to the test, but President Jeff Yurtin and his management team arent people used to resting on their laurels. Rather, theyre normally on the hunt for new ways to clear the next hurdle. <\/p>\n
For Yurtin, the issue at hand was scaling labor for projects that can dampen productivity if theyre not managed correctly. To meet that need, he chose to invest in a Novarc Spool Welding Robot (SWR). The machine offers accurate torch control and machine learning algorithms that can detect different features of a workpiece. <\/p>\n
The unit was designed specifically for pipes, pressure vessels, and other types of roll-welded workpieces. It features an adaptive controls system to help ensure accurate torch control, and AI\/machine learning algorithms to detect weld pool features. <\/p>\n
The SWR can integrate smoothly with the production flow and existing manufacturing processes of customers, according to Soroush Karimzadeh, Novarcs co-founder and CEO. <\/p>\n
The SWR is designed with a small footprint and a very long reach, enabling it to be adopted in almost any fabrication shop, no matter the layout or various requirements, Karimzadeh said. Its designed to be minimally intrusive to the production flow. <\/p>\n
The nature of Joe White Tanks bread-and-butter projects can throw a kink into its work process, however. And that includes persistent labor issues. <\/p>\n
Piping projects can require hard starts and stops with little time to ramp your labor up and down, Yurtin said. Hiring and firing welders for jobs was not our idea of success. We pursued growing our business with a long-term mindset. By adding the SWR to our shop floor, we added capacity strategically and avoided many of the negative implications that come from a short-term, job-to-job labor force. And it has a small footprint; we would have had to install four manual weld cells to do the job of the SWR. <\/p>\n
The SWR also helps to address the nationwide shortage of skilled welders by helping less-experienced operators produce high-quality welds. <\/p>\n
Novarcs machine includes a user interface that has proven easy to learn for operators, regardless of experience level. <\/p>\n
Balancing a stable workforce with changing customer and industry demands can be difficult, Yurtin said. Our organizations culture is very important to our management team. So, as we have grown our companys market presence, we have worked to limit high employee turnover. <\/p>\n
The benefits of workforce continuity are legion. Not only does it give employees a greater sense of job security, but it also results in a more willing commitment to corporate goals. At a time when fabrication shops across North America are experiencing a shortage of skilled welders, the SWR helped limit the impact of this challenge, Yurtin said. <\/p>\n
We used to have a department dedicated to pipe welding, but now we have our SWR operators working with fitters, supporting them, to ramp up efficiency, he said. This has freed up welders to work on other projects in our backlog, shrinking our market lead time and significantly increasing our capacity. The Novarc SWR increased our capacity by 400% without reducing quality. <\/p>\n
The SWR accommodates users with a set of requirements for the fit-up process and provides comprehensive training for fitters. <\/p>\n
This is another way to ensure the integration of the SWR into our clients manufacturing processes is as smooth as possible, Karimzadeh said. <\/p>\n
With a nod to sustaining their strong corporate culture, the companys employees are buying in, according to Yurtin. <\/p>\n
Anyone thats been in the welding business for more than 10 minutes knows that the physical demands are significant, Yurtin said. Welders get tired. <\/p>\n
The ergonomics of the SWR are an immediate benefit for the welder, he added. They're still using their hands, but they dont have to wear a hood, and its much easier with the joystick control. <\/p>\n
The increased productivity also created an unexpected effect on the shop floor that Yurtin recounted with a smile: <\/p>\n
Sometimes its like a game, where the welders see how much they can get through in one day, and were all pumped when we have a super productive day. <\/p>\n
With that sort of team reaction, the machine could even be seen as an aid in recruitment. <\/p>\n
Its a more attractive place to work, and the younger generation of welders is really excited about automation and working with the SWR, Yurtin said. Even the older workers find the learning curve easy to handle. <\/p>\n
Often with automation comes an initial hesitancy, either about using the new technology or the need to make a change that could be perceived as high risk. Yurtin, however, chooses to focus on the ROI. <\/p>\n
Quick payback, he said. As we are able to operate four times faster, we have been able to take on more work. We would need four weld cells previously to deliver the same capacity as one SWR. And the SWR takes 25% to 30% less space. The SWR has increased our ability to accept jobs with shorter lead times, win more projects, and pursue larger bids. <\/p>\n
At the end of the day, safety always comes first for Karimzadeh. <\/p>\n
Novarc cobots are designed to follow the standard for collaborative robots and collaborative robot applications, governed by the ISO 15066 standard, so the cobot is basically equipped with force- and speed-limiting sensors to ensure that if there is a safety event, it can safely stop the work, Karimzadeh said. In addition, the health hazards for welders are significantly reduced, as the welding torch is moved by the cobot, and welders are not exposed to weld fumes and arc light. <\/p>\n
As helpful as those benefits are, the one that stands out for Yurtin is quality. <\/p>\n
We are mainly using the SWR to weld pipe for pressure vessels, industrial refrigeration, ammonia refrigerationbasically pipe for industrial applications, Yurtin noted. These need to be ASME-quality, X-ray-quality welds. And the SWR, besides being super easy to operate, has increased the quality and consistency of the welds. The SWR lays the root pass itself, and the penetration is perfect from root to cap. The SWR can handle it all. And it always passes X-ray inspection. <\/p>\n
Yurtin also credits the SWR for helping to position Joe White Tank as a future-friendly welding shop. <\/p>\n
Were excited to be a showcase for innovation and believe the manufacturing industry needs to adopt new technology to be successful and meet increasing demands for productivity and competitive bidding, he said. Our clients are really impressed by the technology of the collaborative robot in our shop, not to mention the quality, productivity, output, and efficiency. <\/p>\n
Karimzadeh added, The end users of pipe spools are pushing harder and harder regarding project delivery timelines, cost of production, and quality of welds. This is ultimately pushing the industry to automate. Its the only way to meet the timelines, manage the cost, and maintain the quality of the work. <\/p>\n
For Joe White Tank, the search for new solutions to welding challenges is a constant quest for answers that improve its product, its work environment, and, ultimately, its bottom line while reflecting positively on its reputation in the industry. <\/p>\n
