Since the early 1980s, autogenous orbital GTAW welding has been the standard for joining high-purity gas delivery and process piping in semiconductor manufacturing. The demanding nature of these systems, which carry toxic and corrosive gases, requires flawless weld integrity. Orbital GTAW welding achieves this by providing a fully enclosed, gas-shielded environment that prevents oxidation and contamination of the weld bead. The process ensures smooth, repeatable, and high-quality welds, meeting the stringent cleanliness and precision standards defined by SEMI F78-0304. Fusion welding without filler material also reduces potential contamination sources and improves overall system reliability.
Magnatech’s orbital welding systems are specifically engineered for the semiconductor industry’s precision requirements. Digital technology ensures consistent performance without the need for periodic calibration, while integrated weld monitoring software records QC data in real time, guaranteeing every weld meets acceptance criteria. From small-diameter process lines to large exhaust lines for 450 mm wafer tools, Magnatech equipment combines reliability, ease of use, and comprehensive global support to deliver exceptional results in high-purity pipe welding.
