yea i think the speed it really high or fast turn it way down iand make sure you are getting heat penetration or discoloring of the metal on the top and under the weld on the bottm side. those welds look to be just sitting on top not actually penetrating the metal.I t should glow red hot the metal as well as the weld.
when you are welding try and make a C pattern from one side to the other and back and forth.
