What are the carbide inserts on the turning tool welded to the handle?
The first copper burned in the post, and then the borax fell on the top, then put on top of the alloy blade, borax fell on the alloy blade above the flame cutting with money. Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly. Let him cool naturally,
The common oxygen welding and brazing flux borax and welding line! The welding method is as follows: when welding, first use four carbon chloride (CCl4) to wash the welding section of the knife pole, and then use the oxygen and acetylene to turn the tool red and then sprinkle borax! Melt the copper into the top of the knife. Place the blade on the knife and continue to burn until the copper and alloy blades come in contact. An ordinary soldering knife comes out.
Burn copper on the knife rest.Pour the borax onto it.Put the alloy blade on it.Borax fell on the alloy blade top with flame cutting money.Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly and cools naturally.
