Prior to using the silver brazing flux, but do not know how to use this, the finished product is unstable, easy to disconnect. I was welded by spot welding machine. The temperature was about 1000 degrees. I also used solder paste, but the surface of the finished product was oil. What kind of soldering flux can be used to guarantee the success rate of welding?.
For welding copper solder. (the price of 15 yuan 500 grams, buy material stores generally). Solder the solder around the solder joint and then weld it with spot welding machine. This is copper, which is oxidized to the molten pool by resistance heat and then oxidized by air.
Ultrasonic welding machine, without soldering flux, find it yourself
You can sell silver solder pieces - General tddhj, are used for resistance welding, when diluted with water, I hope to help you.
You are welding with spot welding machine! There is no need to use soldering flux! The finished product is unstable and easy to break because your soldering time and current specifications are small! Maybe the specifications of your spot welding machine can not meet the welding requirements! Take my answer, and I'll continue to help you!
