Some MIG welders tips and MIG welders store

MIG welders guides: how to become a more skilled welder and how to select the best welding equipment. Just about everyone who tries TIG welding feels challenged at first. This is understandable, given all the things you have to watch for and think about, while simultaneously coordinating the motion of both hands. In most cases, a foot pedal or torch-mounted amperage control will be used — for starting, modulating and stopping the flow of current. I have coached many people as they learn these skills, and I have received my share of questions over the years. Here are a few frequently asked questions — and answers — that should be helpful, particularly for beginning and intermediate welders.

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.

Some tips on welding equipment, MIG and TIG welders, plasma cutters. Welders with a higher power output can work with thicker metals, but higher voltage welders will require special power supply set ups-either generators or appropriate power outlets. A welder with lower voltage in the 100’s will not be able to handle heavy duty jobs, but it can be plugged in and operated from any outlet. Any welder with power over 200 cannot run off a typical power outlet and will naturally cost more to run. In addition, welders will either run an alternating current (AC) that reverses itself at regular intervals or a direct current (DC) that flows in one direction and does not reverse itself. DC offers a steady rate of energy that leads to hotter temperatures and deeper weld penetration. AC welders usually cost less than DC welders, but the available electrodes are far more limited for AC. In fact, DC welders are more costly but remain popular because their higher power offers a wider selection of electrodes and a number of working advantages such as: simple arc striking, better penetration, and improved control. Welders who expect to work on a wide variety of projects may want to consider an AC/DC combination welder.

MIG Welding Increases Welding Speed: In addition to welding aluminum and other softer metals, MIG-welding works faster, provides cleaner welds, and handles many different types of metals. The downside is its complexity. MIG Welders need direct currents, a steady stream of inert gas, and precise control of their torches. The amount of heat generated from MIG welding provides the deep penetration required for a strong weld, while also melting the feed wire rapidly enough to maintain a higher welding speed than other techniques. Given the inert gas required for MIG welding, keep in mind that this technique cannot be conducted in windy areas. The Right Stick Electrode Increases Welding Speed: There are three kinds of electrodes used for stick welding: fast-fill, fill-freeze, and fast-follow. While each electrode has its advantages, the fast-fill electrodes melt quickly and allow welders to work faster. See more info on MIG Welding Machines.

Not all aluminum alloys are weldable: For example: 7075 and 2024 are not considered readily weldable using TIG welding. You can usually TIG weld them and they might be fine for a tool tote or some little art project…but don’t be fooled. You can’t depend on the welds in critical applications. Take a tree stand for instance. Lets say Joe gets a good deal on some aluminum angle iron at his friends scrap yard and he decides to make a tree stand. Joe has no way of knowing what alloy of aluminum he got from the scrap yard. He makes the tree stand, it holds together and looks just fine. The welds are real pretty…like a stack of dimes. One day he is sitting in his tree stand about 20 feet up a tree. The stress corrosion that has been happening on a microstrucutural level since he finished welding the tree stand finally comes home to roost and CRACK!!
