Digital Solutions Optimize Cutting and Welding Operations

ESAB WeldCloud dashboards provide high-level overviews that allow managers to assess the health of their welding system at a glance.

To help fabricators and manufacturers drive continuous improvement in traceability, documentation, asset management, productivity and quality, ESAB Welding & Cutting Products offers its ESAB Digital Solutions platform.

ESAB Digital Solutions, including ESAB WeldCloud and ESAB CutCloud, connect digital ecosystems for manual/robotic/automated welding and cutting automation, respectively. ESAB offers an architecture powered by Microsoft Azure IoT and utilizing the ThingWorx Industrial Innovation Platform from PTC.

"We collaborated with Microsoft because Azure allows for a reliable and secure architecture that sends data from a digitally connected-system directly to the cloud," said Mike Pantaleano, VP Data Driven Advantage/Digital Solutions, ESAB. "Eliminating the need for an on-premise server or large IT infrastructure especially helps job shops and smaller operations gain the benefits of data management. Our reference architecture using ThingWorx also allows for on-premise and hybrid (on-premise/cloud) configurations, enabling ESAB to configure and scale a connected solution for companies of all sizes."

"The right digital solution lets customers focus on improving their core business activities," said Pantaleano. For companies without IIoT-enabled power sources, he noted that the new ESAB WeldCloud Universal Connector works with virtually any welding power source. It can send data to ESAB WeldCloud, including arc-on time, welding parameters and start/stop information.

Functionality in ESAB WeldCloud enables managers to view high-level dashboards with a simple click. For example, an operations manager could view the following data for a fleet of welding machines: total arc time, average arc time per weld, number of weld sessions, total weight of wire used, wire used by each station and average machine errors per session. A supervisor could easily view statistics for any welding operator, identifying desirable performance characteristics and then seek to replicate them.

ESAB also offers other products in its integrated digital solutions, including WeldQAS, a real-time weld quality analytics product. Ready for connection to ESAB WeldCloud, WeldQAS provides the micro details required by engineers and quality assurance personnel. "Where many weld data capture systems can only log data at 1 Hz, WeldQAS captures data at 23 kHz (and 234 kHz for stud welding)," said a company spokesperson. By comparing measured parameters with reference curves, the system calculates quality marks for each weld seam and provides an instant notification when an irregularity occurs. Faults detected can include poor arc ignition, porosity, burn-through, seam length (too long or short) and seam interruption.

Establishing a Steady State

Without formal data analysis programs, welding and cutting operations tend to overestimate equipment utilization rates and underestimate actual arc-on time when quoting products.

"If you cannot measure it, you cannot improve it. Some welding operations think they are at 30% to 40% overall equipment efficiency when they are actually in the middle teens," said Pantaleano. "The applications and dashboards that are part of ESAB Digital Solutions enable customers to assess their current situation at a glance and then start building baseline numbers. Once they determine what their `steady state' is, they can then identify areas for improvement."

For example, unproductive time might include grinding to compensate for a poorly prepared bevel or removing post-weld spatter. By having ESAB's CutCloud also log data from automated cutting systems, customers gain insights across the fabrication process.

"When fabricators can document activity and associated costs, they can then justify investing in solutions, such as an automated plasma beveller or a premium electrode that reduces grinding time," said Pantaleano.

Documentation and traceability - required by the wind tower, offshore, pressure vessel and other industries - is another area where ESAB's Digital Solutions can help. Spending large amounts of time generating reams of paper to do simple documentation is another example of non-productive time, and it is also prone to errors. Instead, this activity can be done in an operator workflow and is as simple as scanning a barcode. ESAB's new WeldCloud scanning app enables a customer, using a smart phone, to scan parts and associated variables such as operator, welding or cutting machine and consumables. That information is then logged centrally as part of the weld session data.

"Managers can look up a fabrication by part number and easily determine who worked on any particular part with a few clicks," said Pantaleano. "Some of the biggest productivity gains come not from welding or cutting faster, but by harnessing the power of data to make intelligent decisions."
