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.

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, comprising
- endothermically heating a metal to a molten state,
- flowing the molten metal through the weld gap between the edge surfaces for heating the members with the molten metal to cause melting of the edge surfaces,
- continuing to flow the molten metal for a time sufficient to provide a ratio of weld gap metal to total metal flowed of at least 1:50, and
- then terminating the flow of molten metal to provide for weld metal solidification in said weld gap.
A method for welding together two members, such as metallic plates or the like, disposed with their edge surfaces to be joined in mutually facing relationship and laterally separated by a weld gap comprising,
- orienting said members so that said gap extends in a generally vertical direction in relation to the flow of molten weld metal with the gap having a width generally corresponding to the width of the weld joined to be formed,
- endothermically heating a metallic weld material to a molten condition,
- flowing the molten weld metal generally horizontally through said gap from one side to the other at a rate sufficient to melt said edge surfaces for welding,
- continuing the flow of molten weld metal for a time sufficient to provide a ratio of weld gap metal to total metal flowed of at least 1:50 and,
- terminating the flow of molten metal to provide for weld solidification by relatively moving a weld material solidification interface continuously downwardly away from the general flow path of the molten weld metal.
