Copper and stainless steel with silver wire welding is focused on the uniformity of the temperature of the copper and stainless steel temperature to ensure the good, and then because of the copper heat faster, it is not easy to heat, low thermal conductivity of stainless steel, it is easy to temperature, so the stainless steel heating easy above, to coordinate the order of the heating, finally the temperature of the stainless steel can't burnt, burnt after the welding of the welding, and also can be used to replace the silver WEWELDING46 welding wire high temperature welding material, combination with Odin 201 - F solder paste welding, this kind of circumstance is commonly used in some of the larger pipe welding.
