In contrast to the regular TIG process, on the majority of TIP TIG applications, you can typically attain a 200 to 400% hourly increase in your TIG weld production and up to 60% in reduced TIG weld costs, (check out the data on the Cost Comparison page). While the manual, regular TIG weld speed range is typically 5 to 20 cm/min, manual TIP TIG welds are usually made in a weld travel range of 20 to 127 cm/min. With the TIP TIG weld cycle time reductions, you can anticipate at least a 30 – 60% reduction in your TIG gas costs. Also, using the less expensive MIG wire reels will lower your TIG wire costs. Those of you welding with conventional V grooves of 65 to 80 degrees check out further savings below. By the way, if in the past, you have been concerned about weld rework and weld cleaning labor and consumable costs (grinding wheels – brushes), that should no longer be a concern.
There is a global shortage of skilled TIG welders. In contrast to regular TIG, the TIP TIG welder does not have to feed a wire into the weld. Also, a foot control is not necessary. With TIP TIG, the welders can keep their focus on what is happening in the weld pool and use one or two hands to guide the torch. With TIP TIG, manual TIG welders with “low to moderate weld skills” will have the potential to produce extraordinary all position weld quality, and those welders with high TIG weld skills will have the potential to attain a weld quality beyond that achieved with most costly TIG weld automation.
Go to any stainless or duplex workshop and listen to the discussions on the numerous weld and metallurgical issues that can occur with these complex alloys. If you were utilizing TIP TIG at your facility, you would sit back and smile, as the majority of problems under discussion can not happen with a welding process that consistently delivers the highest possible weld quality with the lowest possible weld heat. In contrast, if, however, you were using regular TIG, you would have a process that delivers high weld energy with high weld heat, while pulsed MIG and Flux Cored would both provide moderate weld energy and high weld heat. The more top TIP TIG weld energy and agitated TIG weld pool will produce welds that have the least potential for lack of fusion – weld pores – inclusions. The lowest heat from TIP TIG results in the smallest possible weld oxidation, the lowest weld distortion, the least weld stresses, and the welds will require the least weld cleaning. When the world’s largest nuclear plant (Hanford WA) wanted to weld a 1000 mm stainless pipe to the highest weld standards, they turned to TIP TIG.
The TIP TIG agitated, higher energy, more fluid, slower solidifying weld pool should always provide the best possible side wall weld fusion on any application. This feature typically enables a dramatic decrease in both Vee and J-Groove pipe – plate edge prep dimensions. For example, if your application calls for a traditional, included pipe Vee prep angle of 60 – 80 degrees, if you were using TIP TIG, the included vee edge preps depending on wall thickness could be reduced in the angle bevel range of 40 to 55 degrees. This capability with TIP TIG can enable an additional 25% – 35% reduction in weld labor and consumeable requirements.
Watching a welder using SMAW, Pulsed MIG or Flux Cored on a stainless or other chrome nickel applications (hexavalent issues) and you can readily see and measure the weld fumes generated. Watch a welder using TIP TIG on this sites videos and on clean applications, if the correct data is used it’s going to be difficult to see or measure the weld fumes. The regular TIG manual process creates the highest welder fatigue. TIP TIG eliminates feeding the TIG weld wire or operating a foot control. As TIP TIG welds are made 100 to 300% faster than TIG, fatique and ergonomic concerns should be eliminated with the TIP TIG process.
The ability to utilize a single process for any weld can solve many weld shop issues. Weld managers will be pleased to know with pipe, plate and vessel welds, that from the root to the cap they can use TIP TIG. If the welders are qualified for TIG they are qualified for TIP TIG. If you have qualified ASME procedures for regular TIG you can use those procedures for TIP TIG. Using three or four common TIP TIG weld settings, the welders can weld or clad any alloy, any thickness and make those welds in any position. With TIP TIG we can produce 6 to 8 mm, single pass fillet welds or weld on thin gage (< 1.5 mm / > 16 gage) metals with ease. With TIP TIG we can attache the manual torch to a mechanized carriage or a rotary turntable and this process can be used with robots and most automated welds without costly, complex Arc Voltage Control equipment. It may sound far fetched, but in a 30 minutes demonstration we can show you the four simple weld settings that could be used on every weld in the construction of a nuclear plant or submarine. If you have an interest in this process give us a call, send samples (we weld and video for you) or visit us at our Negoiesti facility. In a short weld demonstration, we will show your organization the highest possible, untouched weld quality always with the lowest weld heat.
Due to the higher TIG weld current, (higher weld energy) and the unique, “agitated weld pool”, the TIP TIG welds will always provide superior TIG weld fusion when compared to regular TIG and the automated Hot Wire TIG processes . TIP TIG is the process that provides the lowest possible weld oxidation from the faster weld speeds combined with electrode negative and an inert gas resulting in the cleanest possible welds. These welds will have the lowest weld porosity-inclusion defects. When dealing with welding sluggish alloys such as Duplex – Inconel – Invar – Stainless and high carbon steel applications, the increased energy and agitated weld pool of TIP TIG dramatically reduces concern with the fusion and porosity issues of these materials.
