Drawn Arc Welding

Tec-Option can also incorporate Drawn Arc Welding into its machines when appropriate. This is the process which joins together a base metal, such as steel, to a fastener. This is completed by a controlled electric arc process. The process melts the end of the fastener to the base metal. Studs are commonly used with this process, but there are many other types of fasteners. Others are known as stud welds, including tapped, unthreaded, and threaded.

Drawn Arc welding provides excellent welding success under a broad range of conditions. It produces a full cross-sectional weld, forming a bond that is stronger than the surrounding metal.
