Abstract

The characteristics of heating processes determine fusion efficiency for base metal and filler material, direction and completeness of metallurgical processes in a welding pool, formation of weld metal structure and heat-affected zone, service properties of welded joints. Under certain conditions in consumable electrode welding with jet gas shield an electrode metal droplet and processes in the weld zone are influenced by the force of shielding gas jet besides the main forces. Significant influence of this force is noted in CO 2 double-jet gas shield. Basing on the research results it was determined that distribution of heat in the electrode, fused metal droplet, arc space, welding pool and parts being welded depends on the shape and velocity of active shielding gas flow.
