MAGNATEC LLC - New: Simple to Operate, Low Cost Orbital Tube Welding System

(be it manual or mechanized weld processes). Although they do follow general guidelines and good manufacturing practices (The 3A Sanitary Standards; AWS D18.1 "Specification for Welding of Austenitic Stainless Steel Tube and Pipe Systems in Sanitary (Hygienic) Applications) for welding sanitary tube systems, worldwide few government agencies have adopted these as mandatory standards.

The perceived high cost of existing orbital tube welding systems is the primary deterrent to their greater use in these industries. The complexity of controls for the welding systems on the market dictate on site training, adding further cost that may represent 10% of the system price.

To offset this concern over equipment cost and simplify the orbital tube welding process, Magnatech has introduced the modular EZ Orbital Welding System. The Model 517 is a tube welding controller that integrates the operation of a standard, commercial GTAW power source with the weld head. The customer can use his existing power source, allowing him to weld both manually and automatically. The

controller has an intuitive symbol-based touch screen user interface. Operation is as simple as selecting tube size and wall thickness, and pressing the Start switch on the head. The operator can adjust these autogenerated parameters by a percentage override to accommodate metallurgical variability in stainless tubing. A USB port allows for software updates and custom developed tube weld programs, sent by

email.

The Model 517 operates a new line of tube welding heads with digital control of rotation speed regulation, ensuring perfect repeatability. The heads incorporate a molded silicone switch panel, allowing remote operation without a separate hand-held remote pendant.

The head is equipped for water-cooling and can be connected to any standard water circulator.

However, it can be operated without one. An internal temperature sensor in the head constantly displays temperature as a bar graph on the display, with the color bars changing from blue to red as the head becomes hotter. If the head temperature exceeds a limit, the operator is prevented from initiating a new weld until the head cools. The operator is notified that he has to reduce his duty cycle, or attach a water

circulator.

A training DVD provides all the instruction necessary for the simple-to-operate system.

Pipe Welding System for Large Diameter ID/OD Applications

The Magnatech Pipeliner is designed to make pipe-to-pipe and pipe-to-fitting welds using the GMAW/FCAW processes. Interchangeable guide rings mount the Head on the pipe, allowing a broad workpiece size range from 16.8 – 152cm (6 - 60”) and larger. The Pipeliner improves productivity by increasing duty cycle, reducing repair rates, and producing welds of consistent quality. The systems are in use worldwide welding process piping for a wider range of industries.

In addition to welding pipework, the pipeline is also used for ID and OD welding on larger tanks, vessels, and ductwork. Flexible track allows mounting on complex curved surface. Standard 2.3m Track section bolt together for longer lengths with magnetic or vacuum attachment. In a typical application, a contractor needed to weld large diameter piping transporting car...

AUTOPROGRAMMABLE ORBITAL PIPE WELDING SYSTEMS

Magnatech’s Pipemaster power source models are used for multipass orbital pipe welding. The Pipemaster 515 model has a 150 amp output, and the 516 model either 200 or 400 amp output. They control weld Head mechanical functions for torch rotation, wire feed, torch oscillation, arc voltage control, and control of arc length. The power sources can operate 22 different models of Magnatech weld heads as well as certain competitor models.

A primary concern in the welding industry is the need to program the equipment for each pipe size and material, and the time needed for welders to learn to program a CNC tool. The proprietary and unique Autoprogramming mode allows operation without programming training. An inexperienced user can enter the pipe’s OD, wall thickness, and material, and a weld program is ge...
