ORBITAL TUBE WELDING SOLUTIONS FOR HIGH PURITY GAS DELIVERY APPLICATIONS

Magnatech-10

Since the early 1980's, autogenous orbital GTAW welding has been utilized for joining the high purity gas delivery and process piping in the semiconductor and related industries.


A semiconductor fabrication facility contains miles of stainless process lines transporting the gases used in chip manufacturing. These gases may be highly toxic and highly corrosive. The high degree of weld integrity required is only achieved by orbital GTAW welding. Most semiconductor welding is done using weld Heads which fully enclose the joint, ensuring superior gas coverage and minimized any oxidation of the weld bead. Wall thickness and tube material generally allows fusion welding to be done in a single pass, without added filler wire. The introduction of the SEMI F 78-0304 standard in the early 1990's provided a comprehensive guideline for orbital GTAW use by specialist contractors.

  • Magnatech orbital equipment is user-friendly - easy to program and use.
  • Magnatech's 800 Series Heads incorporate all controls on the weld head for practical operation away from the power source.
  • Digital technology eliminates the need for periodic weld head calibration – providing the repeatability mandated by the semiconductor welding industry.

Magnatech power sources incorporate integral weld monitoring software, which provides immediate QC data and ensures that every fusion weld is made within defined acceptance criteria limits. Let Magnatech demonstrate what set us apart in equipment ease of use, reliability, with worldwide training and service.

Orbital welding of the predominant 0.25" - 0.50" (6.3 - 12.7mm) tube sizes has become routine to meet the stringent standards in the industry. Recently, the application of orbital tube welding has expanded to the welding of non-critical, gas exhaust and environmental gas purge lines for the new 450 mm wafer processing tools, requiring orbital welding of up to 8" lines.

Unique Welding Solutions

Custom welding solutions designed for unique projects

IF A STANDARD ORBITAL SYSTEM WON’T WORK, MAGNATECH’ S EXPERIENCED ENGINEERING GROUP CAN DESIGN A UNIQUE SOLUTION

Magnatech has engineered hundreds of custom design solutions over forty years.

Magnatech-14

There are many pipe and tube welding applications for which a standard Magnatech LLC system cannot be used. Spatial constraints, workpiece geometry, and proposed use of equipment in hazardous conditions requiring remote operation are but a few of the reasons custom engineering may be required.


Magnatech LLC has engineered hundreds of custom design solutions since our business was founded in 1946. Often, minor changes to weld head design, electronic controls and software are all that is required. Other challenges involve the engineering of an entirely new system with specialized accessories.

The construction and maintenance of nuclear power plants dictates the need for unique pipe welding. An example is the need for remotely controlled welding, where manual welders have limited access due to radiation levels. The weld heads may be required to be located and mounted by remotely operable devices. Video Arc Monitoring systems incorporating miniature video cameras with special filtering allow an operator to view the workpiece before welding to observe fit up; monitor the weld puddle during welding; and visually inspect the completed weld.
