TIG Welding

TIG (Tungsten Inert Gas) Welding is a clean and high-quality electric welding process, considered the most popular choice when used in one-off component repair.  The precision and high-quality of the welding is unmatched within the gas welding processes.  This process has been the backbone of Whitfield Welding Inc. since 1985.


TIG Welding forms an arc between a non-consumable tungsten electrode and the metal being welded. Gas is supplied through the TIG torch to shield the tungsten electrodes and pools of molten weld. TIG welding exhibits greater control over the weld pool than other additive processes.  

Whitfield Welding technicians are unmatched in skill and artistic ability. Combined with proper metallurgical heat treatment processes, there is really nothing that can be welded that cannot be repaired.


Capabilities

25 metric ton crane capacity

8 full TIG welding stations

3 preheat stations capable of holding 25 metric tons at preheat temperature indefinitely (these preheat systems are PLC controlled, taking the guesswork out of quality)

Calibrated thermocouples ensure consistent and accurate preheat weld temperature is maintained throughout the welding process

Experienced mold-finishing to hand work a surface after welding and perform parting line seal-off repair if requested

Guaranteed quality pre-weld preparation and weld line-up on every job

On-site spectrometer to provide an accurate composition of base material for colour matching using best available filler material

Rockwell testing performed on every job that requires oven work, ensuring proper temperature selection

7 ovens having a combined capacity of 160,000 lbs for stress relief or tempering

Ability to research the repair of rare material through experience and our extensive business network
