Soldering and welding of thermocouple wires
The advantage of welding is that when operating in conditions of high temperature welded contact is not broken. Ø if the welding wire does not exceed 0.15−0.2 mm, then the ends are superposed upon each other (distance 15−20 mm), and they wound the thin copper thread Ø 0,1−0,15 mm. Then connected so the ends are heated with a gas burner. Copper when it starts to melt and firmly connects the ends of the thermocouple wires.
Difficulties of welding
Welding thermocouple wires fraught with difficulties, due to the tendency to the formation of pores with a sharp change of solubility of nitrogen, hydrogen and oxygen after the transition metal from solid to liquid. To obtain welds without pore is important for the surface finish of the material, as well as the use of coatings or fluxes, which are able to bind the oxides of Nickel. For this reason, a welding procedure can provide reliable protection of the welding zone from ambient air, degassing of the weld pool and good deoxidation. Effective measure to prevent porosity is short arc welding (up to 1.5 mm), which significantly reduces the flow of gases
