Duty Cycle — The number of minutes out of a 10-minute time period an arc welding machine can be operated at maximum rated output. An example would be 60% duty cycle at 300 amps. This would mean that at 300 amps the welding machine can be used for 6 minutes and then must be ...
But if protective covers were not used, remove any dust or debris that has settled inside the valves. It can cause the torch to malfunction. To do so, stand away from the valve’s opening or outlet (preferably on its opposite side). Turn the valve quickly about a quarter of the way a...

Other fuel gases used in the process are propane, hydrogen and coal gas. These combinations can be used for welding non-ferrous metals and specific applications such as brazing and silver soldering. The same oxy-welding equipment can be used for oxy-acetylene cutting by adjusting the flame profi...
in part the real conditions and this torch cannot simulate any specific application[88], i.e., it cannot be used to directly and precisely predict the behavior of materials for a specific environment. However, the test is very useful in determining the relative merit of different materials[27...

Firstly, the present method can be used at a relatively low temperature, for example, in the range from 600 to 700° C. In the preferred embodiment of the method, an array of bundled and super-aligned carbon nanotubes can be synthesized at temperatures in the range from 620 to 690° C....
Traditional methods for synthesizing single-site catalysts are typically complicated and require special chemicals due to their tendency to agglomerate. In this study, we present a self-disperse copper-based catalyst synthesized via a dry mixing method for acetylene hydrochlorination. During the reaction,...
In order to improve the ablation resistance of C/C composites, an AlSiB alloy (mass ratio of Al/Si/B = 2:4:1) was used as a dissipative agent to fill the pores of a C/C composites matrix by reactive melt infiltration to prepare AlSiB-C/C composites. The microstructure evolution and...
