1 Answer. , works at Studying. Gas giants do have a solid core. Its mostly hard rock, and is surrounded by hydrogen and light gases. It is believed that due to the high pressure , the hydrogen near the core is metallic, but the exact physical composition is a mystery.
Pure argon, when usedas a shielding gas has mild thermal conductiv-ity, and produces an arc which has two zones:a narrow hot core and a considerably coolerouter zone (see figure 10). As a result, thepenetration profile of a typical weld fusionarea is characterized by a narrow âfingerâ atthe root and a wider top.
