As a result, mixture or fusion of more satisfactory material of the flow front is brought. In one execution form, thickness of the outer part ring changes in the part where between of the fan blades which it adjoins differs.スタッグ,ジョナサンブラッドリーバックリー,ドナルドイー...
Steam-tight joints are made between aluminium strips, coated on both sides with plastic, by welding and bonding. The novelty is that at the ends of the strips, small congruent regions are freed from the plastic on both sides and, after placing one strip over the other, the bare regions ar...
Look at haris brand low temperature solder (different kinds for metal and aluminum) (I have used metal solder @ 450F with a hand soldering iron to do a steel box of significant gauge) and brazing if you have a torch (you won't do this with a iron), for a small box you can do i...
A V-section notch is then milled in the join, forming a groove extending into the ring, and welded with the plastic welding material. A rotary support can be used, having a radially-adjustable bracket, accommodating the milling or welding head as desired. ADVANTAGE - Good-quality welding of...
The multi-layered plastic pipe (1) has two extruded layers of plastic, where one of the layers is made of a thermally welded plastic. A welding layer (2) is formed in a nuclear range or an external area of the plastic pipe. Another layer is formed as modified function layer (3,4)....
In all process steps, the temperature of the bodies to be connected is below the glass transition temperature of the plastic. No auxiliary substance remains in the welded body. The flush connection produced by swell welding is durable and strong.Ralf-Peter Peters...
