Abstract :
MB. FINLBY : I think there is quite a lot of information which would be valuable to us on the different materials that could be welded to one another. MB. LBNG : The question of welding dissimilar materials is a very big one and a very dangerous one. Whilst there are quite a number of materials that can be spot welded together, one has always to be very careful in that matter, because of the possibility of welding together materials that, having been welded, may fall apart at some later date due to ageing, corroding, or some other peculiar phenomenon taking place. Certain materials are frequently, welded together, such as the one I have quoted, copper and nickel. Metals like tungsten and nickel are welded, and brass has been welded to steel: but with regard to the welding of brass to steel, we have generally found that it is more the brass that is fused than the steel. They do not join too well.
