Llama Posted May 5, 2012 Share Posted May 5, 2012 So, in my effort to make one of these nifty needle removal thingies I didn't have a matching washer for the top part, so I was going to solder a smaller washer onto a larger one. However every time the solder melted and touched the two metals, it would fizzle and make a rather large amount of smoke, but leave me with no solder at all on the metal. Is there something about soldering two types of steel together? I presume they were regular washers, maybe zinc plated. [EDIT] just had a brainwave and I no longer need to solder it, but the question still stands... Quote Link to comment Share on other sites More sharing options...
shizzl Posted May 5, 2012 Share Posted May 5, 2012 try sanding the surfaces of the washers first,or even warm them up abit? Quote Link to comment Share on other sites More sharing options...
Bling Posted May 5, 2012 Share Posted May 5, 2012 Using flux? If not it's like night and day for getting solder to stick. That was when I did some galv soldering anyway. Quote Link to comment Share on other sites More sharing options...
Llama Posted May 6, 2012 Author Share Posted May 6, 2012 It was apparently flux cored solder, but I guess extra might be needed. Got the speedo apart anyway, but I did have some success with heavy sanding and some vinegar rubbed on. Chur Quote Link to comment Share on other sites More sharing options...
Ned Posted May 6, 2012 Share Posted May 6, 2012 The way you should be soldering two washers together is by getting them both extremely hot, and then just poking it with flux cord solder. Don't put solder on the iron and then try and move it to the washers as by then all the flux will have burned off. This counts for all soldering really. Get your object hot enough and poke it with your solder/tongue Quote Link to comment Share on other sites More sharing options...
UTERUS Posted May 6, 2012 Share Posted May 6, 2012 To add to Ned, it helps to have a bit of solder on the iron to get sufficient heat transfer to the wire. Quote Link to comment Share on other sites More sharing options...
Llama Posted May 6, 2012 Author Share Posted May 6, 2012 Hmmm, I think I need a better soldering iron then, I could only get the solder to melt with holding the iron onto it for quite a while. Obviously what I learned in year 8 metal work wasn't as useful as I thought xD Quote Link to comment Share on other sites More sharing options...
Bling Posted May 7, 2012 Share Posted May 7, 2012 Proper irons are large and heated on a gas burner for ages to get up to temp. not your typical home jobbie though which tends to be crappy 50w electric irons. anyone use one of those 100w gun sort of looking ones? any good?
