IMPULSE-ARC WELDING OF VERTICAL JOINTS IN HULL STRUCTURES

At the Paton Electric Welding Institute (USSR) a so-called impulse-arc welding method has been developed intended particularly for vertical joints in low-alloy and low-carbon steels. The method uses carbon dioxide as the shielding gas and is said to be an improvement on previous carbon dioxide-shielded arc-welding methods in that both speed and good-quality welds can be consistently maintained. It uses a direct-current source with a special internal characteristic allowing very steep surges of current up to a programmed value (hence the name "impulse"). In contrast to previous carbon dioxide-shielded processes, the welding direction is downward and not upward. This method has been used with success in the construction of floating cranes. The article gives particulars of the welding process.
