Maximizing Abrasive Performance When Cutting and Grinding Tube
By Rick Hopkins, senior product manager – metal fabrication, Weiler Abrasives
The terms pipe and tube are often used interchangeably, but there are differences in their construction, how they are sized and where they are used. Because pipe is primarily used for transportation and delivery of gas and fluid, internal diameter is most critical. Pipe is sized by internal diameter (ID) and schedule, which refers to wall thickness. Regardless of the size, pipe is always round.
Tips for Choosing Abrasives for Multipass Welding Applications
By Tony Hufford, category manager – metal fabrication, Weiler Abrasives Group
Multipass welding is typically used to add layers of weld to thick metal joints. This increases the strength of critical welds for applications such as pressure vessels, oil and gas midstream pipeline, shipbuilding and heavy construction. These welds often undergo X-ray or ultrasound testing, since weld failure could be catastrophic.
Trimmable Flap Discs Provide Versatility for Grinding and Finishing Applications
By Rick Hopkins, senior product manager, Weiler Abrasives Group
Flap discs are a commonly used abrasive product in metal finishing applications that offer great benefits for productivity and efficiency. With a flap disc, operators can grind and finish with one product so there’s no need to switch from a grinding wheel to a resin fiber or blending disc. This simplifies product inventory, reduces the downtime spent on product changeover and helps operators complete jobs faster — saving time and money.

Maximizing productivity in grinding applications isn’t just about improving throughput and boosting the bottom line. Using abrasives properly also helps reduce operator strain and minimize product waste.
That is why proper technique plays such an important role in saving time and money in these applications.
There are many tools and consumable options to consider when an application calls for manual metal cutting. Products that can be used span a wide range, including plasma and oxy-fuel equipment, saw blades and diamond cutting wheels.
Resinoid-bonded cutting wheels can address a variety of routine manual metal applications in which flexibility and portability are necessary. By following a few best practices, you can extend wheel life, promote safety, and improve productivity and efficiency within the process.
The welds in pressure vessel fabrication have to be of the highest quality. The proper surface preparation tools and techniques can help to ensure those critical welds pass the toughest inspections.
Proper cleaning plays a key role in a successful welding operation. It impacts quality, since a material surface with dirt or impurities can lead to inclusions or issues such as porosity. Surface cleaning and preparation can also impact the appearance of the final weld, and overall operation costs for rework and labor. Some jobs may require the use of an abrasive product, while other times cleaning can be done with a cloth or chemical solvent.
Interpass and post-weld cleaning are al...
