Abstract
The effect of a charge type of explosives and method of their application at preliminary shock-wave treatment of edges welded on the parameters of HAZ of 17G1S steel joints, made under the water, were investigated. The feasibility of significant refining of grains in HAZ area, decrease in its width, localization of lineage non-metallic inclusions was established. Application of preliminary explosion treatment of edges allows reducing the risk of cold cracking in the HAZ metal.
Keywords: erwater welding, explosion treatment, heat-affected zone, cold cracks
