What is orbital welding used for?
Orbital welding is generally applied to tubes rather than pipes and is considered the standard for joining tubes that are used for gas and liquid systems within the semiconductor and pharmaceutical industries.
What is orbital TIG welding?
Orbital welding is a specialized area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process.
What makes a weld so strong?
The bond, however, is only as strong as the joining material. Welding, on the other hand, cuts out the middleman and joins the original pieces directly to each other. The result is a strong, cohesive bond that’s often as strong as the material itself.
What is the weakest part of a weld?
The toe of the weld is often the “weakest link” in a weld. This is due mainly to geometry and subsequent stress concentrations. The stress at the toe of a weld can be made greater or lesser through welding technique and proper application of acceptance standards (eliminating undercut, limiting reinforcement, etc.).
What is orbital welding?
Orbital welding is a specialized area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process.
What type of material can be orbital welded?
Other thicker wall pipe, materials that need filler material, and materials that are not processed to be welded may need to we orbital welded using a Semi Automatic welding process.
Are there any limitations to orbital welding?
Since there are limitations to almost all types and forms of welding, orbital welding isn’t immune to them. There are limitations and certain disadvantages associated with the orbital welding process as well.
Why do orbital welding variations in consistency matter?
Variations in consistency are an indicator of a problem that must be resolved before continuing. Orbital welding is more commonly performed on tubing than on pipe for several reasons, most important being that the production of tubing yields very consistent outside diameters which is critical to proper fit up in the weld head.
