Wearing appropriate PPE like welding helmets and eye protection gear like goggles to protect workers'' eyes and head from hot slag, sparks, intense light, and chemical burns. Welding workers should remain in the work area for at least 30 minutes after finishing welding to ensure there are no smoldering fires. Consider applying the top …
Narrow Gap welding is ''pipe" orbital welding on parts with a wall thickness typically greater than 1/2" (12.5 mm). The "U" joint profile has a reduced bevel angle to keep the joint narrower. Narrow gap (also called narrow groove) welding requires less space to be filled in, meaning the weld can be completed more quickly and with less ...
Aluminum is one of the most widely used important non-ferrous metals in industry. Aluminum and aluminum alloys have excellent physical properties and mechanical performance. They have low density, high strength, high thermal conductivity, high electrical conductivity, and strong corrosion resistance. They have been widely used in welding ...
The technology is well-established in industry and is routinely used to join turbocharger wheels to shafts, for example. EB welding produces clean, high-quality welds with fine control of penetration depth and a very small heat-affected zone. It is also potentially 20 times faster than laser welding.

The physics underlying the polymer joining is autohesion. The formation of stable bonds between two surfaces of specimens in contact is known as autohesion process. Restriction to the peeling of the welded parts at the primary contact surface is offered by the bonds formed. Autohesion method is initially reported in the year of 1935–7 [ 1 ].
The application of energy storage technology in power system can postpone the upgrade of transmission and distribution systems, relieve the transmission line congestion, and solve the issues of power system security, stability and reliability.
2. Undercutting is another problem that can occur in TIG welding. This happens when a groove is made along the edge of the weld and the place is not filled with weld metal. This occurs when the heat is unevenly distributed and the torch is not held at the correct angle. This will result in a weak joint.
