The design engineer must keep in mind that HAZ can be significantly weaker or stronger than the weld. Accordingly, various parameters of the weld joint needed for design should be established. The procedure for the design of weld joints subjected to static and dynamic loading has been presented....
aUsing AC to TIG weld aluminum evolved from the need to remove the oxide layer that forms on its surface. The EP portion of the AC cycle, in which electricity flows from the work to the tungsten, "blasts" off surface oxides. The EN portion of the cycle does the actual welding, directi...

Naturally, these terms don’t apply to every situation: A “sensing” person learns about history through words and concepts, while an “intuitive” person learns how to weld by using a welder; the terms simply describe a person’s preferred mode. ...
Service life Under normal operating conditions, the expected service life of gas-insulated switchgear 8DJH is at least 35 years, probably 40 to 50 years, taking the tightness of the hermetically weld- ed switchgear vessel into account. The service life is limited by the maximum num...
Weld the welding socket flush with the inner wall of the vessel and grind down. The surface roughness of the ground surfaces must be Ra ≤ 0.8 μm. To comply with 3-A guidelines, always provide a leakage hole of min. 2.38 mm (0.09 in) at the lowest position. ...
