The A-TIG stainless steel active flux is a new type of activator developed by our R&D institute. Welding tests were conducted using this activator on 316L stainless steel tubes with a wall thickness of 7 mm, and it was found that this activator can effectively shrink the arc during welding, increase the penetration depth and reduce the weld width. It enables complete welding in a single pass without the need for beveling. After the weld is covered with filler metal, its microstructure and properties meet the requirements of relevant standards. This activator is a colorless, odorless, and non-toxic solution that offers advantages such as improving welding efficiency, reducing welding costs, and minimizing welding deformation. This activator is applied to the area of the workpiece to be welded before welding; it helps to shrink the arc, thereby increasing the penetration depth and reducing the weld width. It also reduces the impact of impurities on the penetration ability of the welding arc, and the microstructure and properties of the weld are identical to those obtained through conventional TIG welding. The requirements for welding equipment and welding processes when using this product are the same as those for traditional TIG welding. This product is suitable for welding stainless steel and carbon steel, with particularly excellent results when welding stainless steel. For butt welds of stainless steel and carbon steel with a thickness of 8.5 mm or less, it is possible to weld through in one pass without the need for beveling, and to achieve double-sided formation with single-sided welding.

Symmetric welding, intermittent welding, post-weld heat treatment.
