You’d usually opt for different fuel gases depending on your circumstances and what you need to weld. Although it's often used for repair work, gas welding can be turned to for fabricating sheet metal, joining aircraft parts, making automotive chassis and frames, and even joining high-carbon...

To determine the influence of technological and service factors on the quality of the weld joints, an investigation was made of the welding technology characteristics of the processes of welding with the use of different protective gases, the kinetics of development of the diffusion layers in the ...
Oxyacetylene torches are used for welding and cutting metals. Gas welding was done with a combination of hydrogen and oxygen until the late 19th century, but the flame produced by that combination of gases was not hot enough to weld steel. In 1890 a British scientist, Edmund Davy, manufacture...
applications where metal thickness is 0.015 of an inch. One example of such an application would be on an engine blade or an air seal. Plasma arc welding is very similar in technique to TIG welding, but the electrode is recessed and the ionizing gases inside the arc are used to create ...
There are various types of rubber gaskets. Rubber gaskets are used to seal two surfaces together and prevent leakage of fluids or gases. There are several types of rubber gaskets available in the market, each with its own unique properties and characteristics. Some of the common types of rubber...
The welding process is influenced by many factors, such as the need for specific additional tools, shielding gases, welding electrodes and filler material. Let’s have a closer look at some of the most common welding methods used today and find out what makes each of them unique. Different ...
Pipeline, line of pipe equipped with pumps and valves and other control devices for moving liquids, gases, and slurries (fine particles suspended in liquid). Pipeline sizes vary from the 2-inch- (5-centimetre-) diameter lines used in oil-well gathering s
13. Valves: Valves are used in the plumbing system to stop the flow of gases or liquids. There are of three types – throttling, isolation, and non-return. The isolation valves are used to disconnect a part of the piping system temporarily for maintenance or repair. The throttling valves ...
