What is high purity welding?

What is high purity welding?

High purity welding is characterized by the need for precise, strong welds that are devoid of any defects such as voids, cracks, pits or discoloration, outside and inside the tube. Recordability and repeatability are prime requirements of process piping welds.

What is high purity piping?

High purity piping is used in applications where contaminants of any kind cannot be tolerated. Our piping is available in two virgin thermoplastic types (PP and PVDF) for high and ultra high purity applications.

What type of welding is used for pipelines?

Arc welding is the most common type of welding and is a daily activity at pipelines. It brings serious risk of electric shock from the arc that extends between the electrode and the base material used to fuse materials together.

What are the strongest types of welds?

Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.

What is orbital welding machine?

Orbital welding uses a specialised machine that clamps the tube or pipe to be welded while the welding arc rotates around the workpiece (in an ‘orbit’). Because the welding parameters are set by a microprocessor, the settings can be stored and reused, making this a highly repeatable process.

What is high purity fluid service?

High Purity Fluid Service is defined in B31. 3 as “A fluid service that requires alternative methods of fabrication, inspection, examination, and testing not covered elsewhere in the Code with the intent to produce a controlled level of cleanliness.

How do I know if my weld is strong?

A good weld is easy to distinguish. It will be straight and uniform with no slag, cracking, or holes. There will be no breaks in the weld. It shouldn’t be too thin and there should be no dips or craters in the bead.

Is orbital welding hard?

Is Orbital Welding Hard? Because it is automated, orbital welding is not particularly difficult to perform, although expertise and experience is still required to set the welding parameters and make any necessary adjustments during the process.

How much do orbital welders make?

The average orbital welder salary in the USA is $42,900 per year or $22 per hour. Entry level positions start at $37,050 per year while most experienced workers make up to $97,500 per year.

What is high-purity pipe welding and why is it used?

High-purity and ultra-high-purity pipe welding are used in processes where cleanliness of the product is paramount, such as in semiconductor or biopharmaceutical process piping. It is also used where weld strength and reliability requirements are higher than what can usually be obtained— aerospace applications are one example of this type of use.

What is high purity systems all about?

Let’s talk. The High Purity Systems team has developed 7 patents that give the welder and the weld inspector tools to enhance the overall quality of the welded system.

What is “go/no-go” weld profile?

A “Go/No-Go” weld profile tool that removes interpretation of the welding specification and gives the welder and the weld inspector a tool to measure to the final weld parameters per the actual welding spec. Many times we’ve encountered situations where the welder and the inspector each interpret the orbital welding requirements differently.

What type of certification do your welders have?

All of our welders are certified to Section IX of the ASME Boiler and Pressure Vessel Code (B&PV), continually meeting and exceeding a wide array of welding standards. We are well-versed in welding similar and dissimilar metals, both at our fabrication facility and on your project site.
