Welding of Grade 91 (9Cr-1Mo-V) chromium-molybdenum steel has presented numerous challenges since its introduction in the 1970s. The gas tungsten-arc (GTAW) process can produce welds of high quality; however, manual welding can be expensive and labor intensive, requiring skilled welders with extreme hand-eye coordination and dexterity. Grade 91 productivity... Read More
The Evolution of TIG…TIP TIG
TIP TIG is a semi-automatic high deposition metal transfer (HDMT®) variant of the manual TIG welding (GTAW) process. As opposed to the manual GTAW process, in TIP TIG, the continuously fed of material as well as preheated filler metal increases the deposition rate. The automatic TIG wire feeder includes a wire feed agitation mechanism that improves the dynamics of the molten weld pool. The agitation increases fluidity of the weld puddle and helps break up impurities and releases gases for reduced risk of inclusions and porosity.
Standard welding machines can be connected to the TIP TIG process. Our patented wire feed system introduces a vibration to the filler wire and as well as a pre heat to the filler material prior to entering the weld puddle. The vibratory effect comes from a mechanically applied agitation using a 4-roll wire drive unit. The hot wire current is created by a secondary power source within the TIP TIG wire feeder.
The TIP TIG welding process is most beneficial on alloys like Carbon Steel, Stainless Steel, Duplex and Super Duplex Stainless Steels, Inconel, Stellite, Titanium, Hastelloy, Copper Nickel, Nickel Chrome Alloys and for Aluminum welding.
The core application of the TIP TIG process is to attain higher travel speeds and increasing productivity of TIG welds using HDMT GTAW.
