What should I do to open the column in brass oxygen welding?

Brass oxygen welding list shows that the weld strength is not enough. Originally, brass oxygen welding belongs to the brazing principle, unlike fusion welding, which really melts the matrix. Therefore, if there are cracks in brass oxygen welding, it is suggested to change Viodin 204S brass argon arc welding wire into argon arc welding. Remember, at this time, it is necessary to replace the welding wire with brass argon arc welding wire instead of brass gas welding wire.
