Dip Brazing
Dip brazing is a process where components are immersed in molten salt or liquid filler metal to transfer heat quickly and evenly. It is often used in electronics manufacturing.
Physicochemical Action Mechanism
The parts are dipped into a molten solder bath, transferring heat quickly and evenly to the parts. The solder is a good heat carrier and prevents air bubbles from forming between the parts.
Metallurgical Relevance & Welding Risks
Dip soldering has the advantage of rapid cooling, which leads to a fine grain structure. This reduces stress and prevents cracks or hot cracking. However, too fast cooling can lead to glass-hard copper alloy that is not well suited for mechanical loads.
Workshop Practice & Action Instructions
• Use molten salt or liquid solder as a heat carrier.
• Ensure the solder bath is stable and evenly heated.
• Dip the parts slowly and controlled to avoid air bubbles.
• Cool the parts after soldering in a cold cleaning agent to ensure a clean surface.
