Brazing joins parts by heating them to more than 840°F and applying a filler metal that has a melting temperature below that of the base metal. Filler metal flows into the joint by capillary ...

Brazing is a process by which two metals are joined together. During the brazing process, a filler metal, which is otherwise referred to as a solder, is brought to a liquidus temperature that is ...

The process of brazing ACR tubing is a common task for many refrigeration technicians. Although this is relatively simple, there are some system problems that can occur if some basic brazing ...

Brazing and soldering practices are one of many areas in the HVACR field where what is commonly practiced isn’t what’s best, and what’s taught doesn’t apply in all cases. Let’s start with the basics.

Brazing is a critical metallurgical process employed to join titanium alloys, utilising filler metals that melt at lower temperatures than the base materials. This technique is particularly ...

New research shows small additions of nickel and yttrium can dramatically improve the performance of aluminum brazing fillers. This could be a route to stronger joints at lower processing temperatures ...

Remember when copper was commonly used in mobile air conditioning? Hans Fernqvist does. He’s a leading technical expert on climate AC systems at Volvo Car Corp. and has been actively involved in the ...
