There are several methods for thin yellow dao copper. There is definitely one du for you
1. For medium thin and thick ones, such as dao2-3 mm thick, you can use silver-based VOD203 solder for flame soldering and VOD201-F solder paste.Medium and thin models Brass padlock
2. For medium-thick or even thicker ones, if you have the basis of argon arc welding, you can use Weiouding brass argon arc welding wire DC argon arc welding. Remember it is brass argon arc welding wire, not gas welding wire
3. If it is thicker, use the second method to weld on the basis of preheating
5. If it is ultra-thin, such as 1 mm or even less than 1 mm, you can use ultra-low temperature 179 degrees M51 welding wire with M51-F flux for welding. This kind of welding can be done with WE53 special liquefied gas spray gun or soldering iron.
