Oxford Mig welders best online store: TIG Welding / Gas Tungsten Arc Welding (GTAW) — TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually argon) and a filler metal, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy that is conducted across the arc through a column of highly ionized gas and metal vapors known as plasma. TIG welding is most commonly used to weld thin sections of alloy steel, stainless steel and nonferrous metals such as aluminum, magnesium and copper alloys. The process grants the operator greater control over the weld than other welding processes, allowing for strong, high-quality welds. TIG welding is comparatively more complex and difficult to master than other processes and is significantly slower.
Here at OXFORD WELDERS we have taken a totally different approach to things. We dont ever want to make unreliable machines with a short life! So we dont make inverters. We have developed our own unique solution, OXFORD HYBRID technology. (Transformer chopper technology). This technology is not totally new & some of the largest American manufacturers use similar designs in their most industrial machines. We think we are the first manufacturer to use this for medium sized machines. By working with Mitsubishi products we have achieved performance levels unthinkable a few years ago. If you look at the performance specs of our machines you will see why our products sell well & get great reviews. Our HYBRID machines give you the best possible welding performance, very low power consumption & importantly superb long term reliability & lifespan. Read additional info at Oxford Plasma Cutters.
All welding requires the application of heat, which melts the metal being welded. With the TIG process, the heat comes from an electric arc that streams between the electrode in a hand-held torch and the metal being welded. The arc and molten metal are shielded by an inert gas, which protects the electrode and base metal from oxidizing. Filler rod is usually added to the puddle of molten metal as the weld progresses. The essence of making a good weld is heat control, which is governed by how you modulate the arc as it streams from the torch. Let’s look at this in detail.
Eliminate Any Extra Welds from the Design: Look for ways to modify product designs to eliminate unnecessary welds. For example, one company that manufactured boxes originally had a design that called for welded lift handles on each side of the box. By simply changing the design of the box to cut out lifting slots, it eliminated the need for welding the handles – saving time and money. In another instance, rather than making a part with an open corner, the design was changed to accommodate a closed corner, which meant 1/3 less metal required to fill the corner. Look for Items That Can Be Welded Rather Than Cast: We’ve already discussed ways to eliminate welds to create efficiencies, but what about adding welds? In some cases, it may be more cost effective to weld metal pieces to a part rather than cast the entire component in a costly alloy or exotic metal. For example, a company that originally used a part cast in a high-nickel alloy found that 50 percent of the part could be composed of standard, structural steel which allowed a savings in material and thus a savings in total cost. Also, the company was further able to redesign the part so that it was more efficient. Explore more details at https://www.weldingsuppliesdirect.co.uk/.
