Stainless Steel Welding Applications

In stainless steel welding, there are many parts of the process that are critical to maintaining the stainless steel’s integrity and corrosion resistance. Choosing the proper filler metals and joint prep are all important to welding stainless steel, but those two items are easily controllable. The other major critical point to consider when welding stainless steel is the welding process itself. Too much heat or rapid heating and cooling can compromise the integrity of the metal and the corrosion-resistant qualities of the stainless. The process of welding stainless is very specialized and must be performed by an experienced welder, that is, unless you have a TIP TIG machine.

The regular TIG stainless steel welding process has provided the lowest manual weld deposition rates and slowest weld speeds, making welding stainless steel much harder than normal steel. Speeding up the TIG welding process, while still retaining the same weld quality requirements, was not possible before TIP TIG. The key to achieving the highest energy agitated welds producing the highest possible weld quality at a speed much faster than traditional TIG is TIP TIG’s revolutionary high-speed oscillation of the fill wire. Now that the process has sped up, TIP TIG stainless steel welding consistently enables lowest possible weld heat while still retaining the best mechanical and corrosion-resistance properties.

TIP TIG 14 gauge Stainless. TIP TIG 14 gauge weld travel rate is approx. 48 inch/min.

The 14 gauge weld in the video would typically be made on steels and alloy gauge parts 0.070 to 1/8, (1.8 – 3 mm). That fillet weld length in the video is approx. 12 inch (30 cm) long. Regular TiG weld travel rates on parts like this would be in the range of 5 to10 inch/min. The TIP TIG weld speeds on this gauge stainless part was 48 inch/min.

With TiP TiG, the welder does not have to feed a weld wire or operate a foot control which dramatically reduces the TIG skills. As you can see in the videos, the TIP TIG welder can focus strictly on the weld and use one or two hands to guide the torch in which the weld wire is consistently fed into the optimum arc position directly under the tungsten tip. With all manual TiP TiG welds, you should note the weld continuity and uniformity (like automated welds) that comes from the constant fed smaller weld wires. TIP TIG produces the lowest possible weld heat which means you should attain the smallest possible weld HAZ, the lowest possible distortion, no spatter and always that unusual, untouched weld cleanliness.

On all stainless steel welding applications, while we are welding at MIG weld speeds, we have no visible Hexavalent Chrome fumes and no weld spatter.
