Magnatech LLC develops orbital pipe and tube welding systems for the most demanding industries – used in extreme environments from +49 °C (120 °F) desert heat to −40 °C (−40 °F) winter conditions. From aerospace to sanitary pharmaceutical and food piping, Magnatech provides the systems needed to meet guidelines and pass inspection.
Aerospace Industry
The aerospace industry was the first to recognize the necessity for automated orbital welding. Critical fuel and hydraulic control lines are exposed to extreme cyclical mechanical and thermal stresses, which drove the search for reliable joining technology to replace mechanical fittings. A single aircraft's high-pressure systems can contain more than 1,500 joints, all welded with automated orbital equipment where precise heat control prevents distortion.
- Digital control ensures perfect, repeatable welds required by aerospace standards.
- Weld monitoring and QC reporting for each weld made.
- Autoprogramming generates weld parameters and simplifies operator training.
Food and Beverage Industry
Magnatech is a leading provider of orbital tube welding systems that help the food, dairy and beverage industries meet strict hygienic requirements for sanitary tubing. The move to Clean-in-Place (CIP) technology and the ASME BPE (Bioprocessing Equipment) standard has increased demand for automatic tube welding that delivers consistent, full-penetration welds.
- The EZ Orbital System is a cost-effective tool designed for this market.
- Models available for fusion only (open and closed arc) and with wire feed.
- Reduces fabrication and installation time while improving weld consistency.
Fossil Fuel Power Generation
Orbital welding systems have long been used in fossil-fuel power generation, where welds must often be made in tight axial and radial clearances during construction and maintenance. Magnatech's compact weld heads handle multipass welding on materials requiring high preheat temperatures.
- Used in fabrication of superheaters, reheaters and economizer assemblies.
- First to provide Autoprogram Generation for multipass pipe welding.
- Position-based programming allows up to five continuous passes without stopping.
Nuclear Power Generation
Orbital pipe and tube welding has been used in nuclear power since the first commercial plants. Automated orbital welding eliminates the variability of manual welding and precisely controls and monitors heat input – critical for many nuclear applications where every weld is tested.
- Long history of use in PWR, BWR and CANDU reactor designs.
- Video Arc Monitoring systems for welding in high-radiation areas.
- Power sources engineered for data logging of welding parameters.
Offshore Oil and Gas Production
Exploration is increasingly moving offshore, where welds face extreme environments. Magnatech equipment is used extensively for offshore pipeline welding using GTAW and FCAW. Corrosion-resistant alloy (CRA) clad pipes used against hydrogen sulfide and carbon dioxide require special welding techniques that Magnatech systems reliably deliver.
- Specialized pipeline welding systems for offshore welding.
- Proven expertise in welding CRA clad piping.
- Operator training and weld procedure development worldwide.
Pharmaceutical and Biotechnology Industry
Orbital tube welding is the most effective method for generating crevice-free welds essential to controlling microorganism growth in hygienic process and fluid-delivery systems. The ASME BPE standard requires automatic (machine) welding techniques such as orbital tube welding, particularly important for CIP systems and sterile Water For Injection (WFI) piping.
- Digital control ensures repeatable welds required by ASME BPE standards.
- The Tubemaster provides weld monitoring/QC data for every weld.
- Autoprogramming simplifies operator training.
Petrochemical and Chemical Plants
Chemical plants use tubes and pipes from small to large diameters, in standard carbon and stainless alloys and highly exotic custom-formulated alloys requiring exacting procedures. Automated orbital welding minimizes and precisely controls heat input, which is often critical to maintain the properties of special alloys, and its high duty cycle shortens costly maintenance shutdowns.
Process Piping
Magnatech orbital pipe welding systems help contractors consistently meet ASME B31.3 code standards across the full spectrum of pipe size, wall thickness and alloy. Water treatment facilities for potable water and wastewater require extensive pipe welding, often within the confines of service tunnels.
- Precise machine control for corrosion- and temperature-resistant alloys.
- Allows lower-skilled welders to meet industrial piping codes.
- Autoprogram Generation for multipass process piping welding.
Semiconductor Industry
Since the early 1980s, autogenous orbital GTAW welding has joined high-purity gas delivery and process piping in the semiconductor industry. Fabrication facilities contain miles of stainless process lines transporting toxic and corrosive gases, where the required weld integrity is only achieved by enclosed-head orbital GTAW welding under the SEMI F 78-0304 standard.
- User-friendly equipment, easy to program and use.
- 800 Series Heads with all controls on the weld head.
- Digital technology eliminates periodic weld head calibration.
Shipbuilding Industry
Commercial and naval ships have extensive pipe work for power, fuel and water subsystems, often welded in cramped conditions with minimal clearance. Magnatech's compact weld heads produce multipass welds meeting any code standard, and readily weld copper-nickel pipe that is difficult to weld manually.
- Compact weld heads used in shipbuilding and maintenance worldwide.
- Position-based programming allows up to five continuous passes.
- Compact, lightweight power sources facilitate welding below deck.
Water and Gas Pipeline Industries
Welding cross-country oil, gas and water pipelines is one of the most demanding tasks in mechanized welding. Magnatech's systems are in daily use in Saudi Arabian desert heat above 49 °C and Canadian winters down to −40 °C, where equipment reliability drives joints-per-day productivity.
- Handles pipe from 168 mm (6") to 1830 mm (72") with standard Guide Rings, larger with Flx-Track.
- Uphill mechanized welding virtually eliminates repairs and suits lower-skilled welders.
- Push-Pull wire feeders allow economical 15 kg (30 lb) spools.
More Orbital Welding Applications
Many applications fall outside standard categories – water pump lines in deep-shaft mines, large HVAC systems, flexible metal hoses and weld overlay buildup to replace metal lost to corrosion and erosion. The high duty cycle of automated welding significantly reduces both project time and cost.
Unique Welding Solutions
When a standard orbital system won't work, Magnatech's engineering group can design a custom solution. Since 1946 Magnatech has engineered hundreds of custom designs – from minor weld head changes to entirely new systems, including remotely controlled welding with Video Arc Monitoring for high-radiation nuclear environments.
