There is described a method for welding thin metal sheets (A, B) by the localized heating of limited juxtaposed zones of the metal sheets to be welded to cause their fusion and to form spot welds (S). In each weld zone, the metal sheets (A, B) are heated and fused along a closed...
Few 17-year-old girls know how to weld(焊接) two metal pipes together.I have learnedthis skill in the past five years as a(n)_41 for my father's personal plumbing(管道装置)business. This summer job often needs to deal with the mess that causes physical and mental42 , and, to some...

How to Weld Steel Pipes Welding pipes is one of the simplest and most durable ways to join piping together and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten inert gas or SMAW (stick metal arc) welding. Before welding two pipes together, avoid any ga...
The invention relates to an electric arc welding method for welding at least one metal part including an aluminum based surface coating, using a shielding gas. According to the invention, the metal of the aforementioned metal part is melted by the electric arc alone without the use of any lase...
This guide will teach you how to weld steel with a flux core welder. It is essential that you are already familiar with working with metal, such as cutting it, and are aware of the safety measures associated with this type of work. Cut the...
A blowtorch made it easy to cut and weld metal more precisely by focusing a high temperature on a small point. Welders and plumbers are not the only ones who wield these fire-breathing machines. Regular folks may keep them around the house for various tasks including lighting cigars, mending...
Shielded metal arc welding is the standard way to connect two natural gas pipes together. You first need to tack weld the two pipes together to hold them in place when welding. Then, you can apply butt welding techniques to create the main weld. If you do not have experience with pipe ...
Weld metal: More isn't better.Codes spell out specific weld size requirements, including the maximum allowable height of the bead above the plate. The trick is to lay just enough weld metal to create the strongest joint—and no more. A highly convex bead doesn't make a weld stronger, but...
A welder will be present anywhere metal needs to be permanently fused together or broken apart. If you are planning on a career as a welder, it is crucial to do some research on the field. Factors that you may want to consider before you decide include the job description, as well as ...
