Welding PSA: Never let silver contact acetylene
- sacnoradhq 3y agoIf you were a welder brazing furnace piping with silver or sweating on a drinking water main valve with acetylene and silver solder because MAPP gas just wasn't fast enough for you to make it home in-time for the mrs'es schedule, realize you're playing Russian roulette in the synthesis and manufacturing of a bomb with variable stability from untouchable azide to friction/shock insensitive triggerable by extreme process or repair heat. Just never, ever let silver and acetylene gas touch.
- anenefan 3y agoA more accurate announcement would reflect a caution against using silver coated pipes for acetylene transport or high silver solders for joining any pipe work that risks internal exposure to the gas. Using the gas itself (as a fuel) to weld with / using high silver alloys isn't a problem though. I dimly recall in my locale there was a prank back in the 80s that used a Silver acetylide solution that had been dried onto some surface ... but only small milligram [1] amounts I guess.
