Inert Gas Purging with Orbital Welding (World Pipelines - Global Energy)

It is often difficult to meet requirements for quality using manual welding. Orbital welding has become an essential process with many tube and pipe fabrications since modern equipment can be fully automatic and reliable and offers repeatable results.

Performance of TIG Electrodes (incorporating MultiStrike™ Tungstens)

The increased use of mechanised and fully automated TIG welding techniques has highlighted the demand for improved performance from the tungsten electrode.

Dr Michael Fletcher of Delta Consultants discusses experience with weld purging on stainless steel pipes.

Few would disagree with the fact that making high quality welds in stainless steel demands skill.

As we entered the 21st C we were made all too familiar with demands to reduce manufacturing costs. Remaining competitive in what had become a global rather than a national economy became a driving force when examining production methods.

Design, fabrication, and maintenance practices that can meet exacting purity requirements of ASME 31.3 are crucial to the food, pharmaceutical, and semiconductor industries

Demands for improvements in piping fabrication quality have risen exponentially in recent years.

Proper preparation can lead to an increase in electrode life and better welds.  Optimizing Tungsten Electrode Performance.

By Dr Michael J Fletcher

While hand grinding can be tolerated in some circumstances, producing welds for safety-critical applications and where weld properties must meet stringent inspection criteria needs a more controlled approach. Following are some tips for optimizing electrode preparation, which can lead to a significant increase in electrode life.
