Cobots Take Grinding from Good to Great

Professional welders know a good weld when they see one. They also know that there are some obvious reasons as to why good weld beads are ground once finished, such as better appearance, proper joint fit, or paint prep just to name a few. But great grinding takes time, precision, and a lot of hard work.

Proper Robotic Welding Gun Configuration

The welding gun is a vital piece of equipment in a robotic welding system, serving as the conduit for the welding wire, gas, and power. However, it can sometimes be an afterthought when companies implement an automated welding solution. Unfortunately, this oversight can lead to a host of problems, not to mention frustration. That is especially true for first-time users making the investment.

Top Four Reasons to Use Arc Thermal Spray for Machine Components in Your Job Shop

Arc thermal spray, also known as twin wire arc spray, is one of the older and simpler forms of thermal spray coating. Thermal spray technology has come a long way, from spraying basic metals and simple alloys to, now, spraying extremely hard ceramics and carbides. These advances don’t mean arc thermal spray is any less valuable. Thermal spray certainly isn’t the cure-all for everything, but each process has a specific fit in the coating world. Among many things, twin wire arc thermal spray is great for dimensional restoration, sacrificial corrosion coatings, custom alloy coatings, and bearing surfaces. Arc spraying is also fast and economical, which can translate into faster turnaround and better margins.
