Plasma Cutter | | Title: | Plasma Cutter | | URL: | https://www.weldingsuppliesdirect.ie/ | | Description: | Identify the types of welding projects and materials you will weld most of the time. Are you creating metal sculptures? Do you intend to restore an old muscle car in your garage? Does the motorcycle you bought years ago require some fabrication? Maybe you need to do basic repair on farm equipment. Taking the time up front to identify the projects that will occupy the biggest percentage of your welding activity will help you determine the specific thickness of metal you will likely weld most often - and ultimately help you select the most suitable welder. Time to get a bit more specific. Let's take a look at what welding process you can use for each metal type. Keep in mind that many of these materials are also processed using varying combinations of two or more metals to reinforce strength and functionality.
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. Searching for the best MIG Welders? We recommend Welding Supplies Direct & associated company TWS Direct Ltd is an online distributor of a wide variety of welding supplies, welding equipment and welding machine. We supply plasma cutters, MIG, TIG, ARC welding machines and support consumables to the UK, Europe and North America.
For TIG welding, the metal needs to be clean; no rust, scale, paint, etc: TIG welding is not nearly as forgiving as Mig or stick when it comes to dirty metal. For TIG welding, the metal needs to be clean; no rust, scale, paint, etc. that means hot rolled steel needs to be ground to shiny bright metal.not just polished over. Welding hot rolled steel without grinding will make you look bad. Don't do it if there is a chance someone might see it. Windy conditions or drafts in the welding area and you will lose shielding coverage and get pinholes/porosity in the weld . If you have to TIG weld in windy conditions, you are going to have to spend some time making wind breaks out of cardboard, plastic, or whatever you can get. TIG welding will just not tolerate much of a breeze much less a gust of wind. And please don't try to TIG weld with a coat hanger or gas welding rod. They will bubble and hiss.
3 Plasma cutters advices: how to become a more skilled welder and how to choose the top welding equipment. Use the smallest tungsten that will get the job done. Use the smallest tungsten to get the job done. .within reason. Another way of saying this is don't just use a 1/8" electrode for everything. There are jobs where a 1/8" electrode is great like for welding 3/16" thick aluminum. But what if you are welding on the edge of a .030" turbine blade? A .040" electrode will be plenty to handle the 15 amps and will give much better starts than even a 1/16" electrode. Too large an electrode can cause an erratic arc and contamination.and A bad start where the high frequency tries to arc up inside the cup and off the side of the tungsten can easily melt off a thin edge and scrap an expensive part. 2% thoriated or lanthanated tungsten electrodes hold up at high amperage better than most all other electrodes. When welding at higher amperages, often times you can use one size smaller electrode by using 2% thoriated or lanthanated. And that is a good thing. |
