תהליכי חיבור ריתוך – Welding, תהליך חיבור בו חומר האם מומס. עם או עם או ללא תוספת לחם. אינוך – Brazing, תהליך חיבור בתוספת לחם ללא המסת חומר האם, בטמפרטורה מעל 450 הלחמה – Soldring, תהליך חיבור דומה לאינוך בטמפרטורה מתחת ל450 מעלות. חיבור מכני – חיבור בעזרת ברגים ומסמרות - Mechanical חיבור בהדבקה - Bonding חיבור הייברידי - Hybrid

Spot Welding
12
Brazing A braze is a filler metal with a melting temperature above 450 °C. According to this definition, brazing is performed at temperatures above 450 °C.

Example: Al heat exchanger
14
Soldering If the temperature is below 450 °C, the process is called soldering
