Lathe tool welding method!! Concrete action steps!! Precautions should be taken!
To make the handle Find the alloy to be welded You want acetylene and oxygen to ignite Burn the copper strip in the position of welding Sprinkle powder before it is set (a white powder is not good for me) Put the alloy on it. Waiting for him to cool
The children of the wrong people upstairs, not even borax? Still teaching people to burn knives? Actually very simple 1: the alloy tool head and the blade are smaller and can be placed directly in the Angle (the cut Angle you want) 2: from beneath the sword of the cutting tools by gas welding rod heating (heating alloy material loss of the cutting tools for a long time, reduce the tool life), make the cutter bar and reach the orange of the cutting tools, and borax from above by welding melting copper electrode, copper water gap filling with respect to ok. Notice: 1: the tool holder and tool bit interface level off is smooth with no greasy dirt and rusty spot, the temperature must be orange, uneven copper water temperature is too low, welding, tool rod is too large to heat. 2: the welding tool should be cooled slowly in the natural temperature, not water or other liquid to cool rapidly, preventing the crack of the tool.
Using the oxygen to heat the pole of the knife with the use of borax and copper electrode, it will burn red. Put a little bit of borax, put on the head of the knife, preheat the electrode with borax, and then melt the electrode and insert the stick. Borax's name is sodium tetraboride.
