During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
In GMAW (gas metal arc welding) practice, horizontal welding is a position that many beginners have mixed feelings about. It’s easier than vertical or overhead welding, but if parameters an...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
The appearance of the weld matters just as much as its strength. Many of us have been there—the root pass looks great, but when it comes to the cover pass, the weld ends up dark, rough like sandpa...
The preparation work before welding is as important as the welding process, which is directly related to the welding quality and effect of the finished product.
