Summary:Title screen
The author analyses the changes of heat distribution in welded joints of 30HGSA steel depending on different types of gas shielding. It is determined that thermal cycles in the weld metal and in the heat-affected zone differ depending on the type of gas shielding. In the range of 760...790°С the temperatures level and a hotter metal of the weld becomes less hot in comparison with the metal of the heat-affected zone with any type of gas shielding. The rate of temperature saturation in the welded parts is a little higher with double-jet gas shielding, levelling of the temperatures between the weld metal and the heat-affected metal occurs 1...1.4 seconds earlier than with conventional single-jet gas shielding.
