Jun 10 2004 A new area is welding of dissimilar materials like steel and aluminium which is known to be impossible in conventional welding. Fig. 3 shows an overlap weld of a 1. mm thick steel plate to aluminium.. For a good wettability the material should be free from oxides before welding and the speed and temperature should be balanced to reduce the intermetallic layer
The first heating causes thermoset materials to set similar to a 2 part epoxy resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time it would simply burn. This characteristic makes thermoset materials poor candidates for recycling.
