NARROW GAP

steel mec sald produces state of the art welding solutions for tandem Narrow Gap Submerged Arc Welding (NGSAW).
steel mec sald been devoted to welding automation since 1952, and Submerged Arc Welding (SAW) is our core activity. In this context, tandem NGSAW technology is our flagship system with important awards in the nuclear field and other heavy industry applications. We offer turnkey solutions starting from automation of the process and developing all parts of the system, included a custom narrow gap tandem SAW head and complete monitoring of the welding zone using an advanced laser scanning system for tracking and scanning of the groove. By using an automated five axis system, it is possible to achieve the desired welding shape controlling the welding zone in real time. The Steel Mec Narrow Gap torch includes a feature to tilt the nozzle in order to respect the sidewall offset programmed in the welding shape, weld pass by weld pass.
