Abstract
A method of welding together two members placed with the edge surfaces to be joined in mutually facing relationship and separated by a weld gap. A weld material is endothermically heated to a molten state and flowed through the weld gap for heating the members to cause melting of the edge surfaces with the weld metal flow being continued for a time sufficient to provide a ratio of weld gap metal to total metal flowed of at least 1:50, and then the flow is terminated to provide for weld solidification.
