How can the aluminium band be welded to the steel shell?
Aluminum strip can be welded to the steel shell, mainly to see the aluminum strip thickness, to select the welding method and welding materials according to thickness.
Welding method:1) to deal with the surface of the aluminum strip and steel shell surface oil and oxide skin.2) after the low temperature welding wire 303B Wei Odin flatto, then put between the aluminum strip and steel shell.3) the resistance is placed in the welding place where the flat 303B wire is welded.4) in the premise of high temperature continuous heating, 303B welding wire melting forming, bonding aluminum strip and steel shell.Welding attention method:1, resistance welding current output must be enough, otherwise the parent can not reach the temperature, welding wire will not be adhesive.2, the surface of the oxide film must be handled clean, so that the aluminum band is easy to glue, otherwise, the aluminum oxide film will hinder the welding line bonding aluminum belt.
If it is more than 0.5 mm by resistance heating welding, welding materials need to use the 303B welding wire Odin wei.Welding tools: carbon block welding, welding with two electrodes.
