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.

Welding Automation Helps Build the NYC Skyline

Fabricating a project that uses more than 1500 tons of steel or welding 60-ft joints on beams and trusses for some of the largest buildings in New York City may seem stressful. Yet to the guys at Orange County Ironworks (OCI), that’s just an average day. Working in tandem with its sister company, Gabriel Steel Erectors, OCI is one of the biggest players in the city for the fabrication and erection of structural steel on both new structures and retrofits of existing buildings.
