linde GASES FOR BRAZING in the transportation industry TO MINIMIZE OXIDES AND FORM STRONG BONDS
Forming stronger bonds
Brazing is a joining process that heats filler metal to a fluid temperature and evenly distributes it between two close-fitting parts. Brazing allows for a tighter bond in comparison to welding or soldering. The molten filler metal bonds with the base metal to form a strong, sealed joint. Brazing also allows you to join the same or different metals with considerable strength, giving greater flexibility.
Furnace brazing is best for large batches to be joined at one time. This process allows for controlled heat levels and increased production. The brazing process requires high temperatures and a filler metal that is above 840°F (450°C). While furnace brazing has its benefits, the high heat can cause oxidation to occur on the surface of the metals if the atmosphere you are working with contains oxygen. These oxides on joints can hinder the process. The right atmosphere should be able to protect the parts from oxidation. That’s why we provide a reducing atmosphere that consists of hydrogen and nitrogen to minimize oxide formation and reduce existing oxide, ultimately resulting in higher quality joints.
A complete system design
Whether you need to update or design a new gas supply system, we can help. From providing information on the best gases to use for your brazing process, to installing the complete system at your site, there is a team of experienced professionals ready to help meet your needs.
After your installation is complete, our monitoring system can check the atmosphere in your continuous and batch furnaces and control the volume of gas introduced into the furnace. The advanced atmosphere control system helps generate higher quality parts and increases the efficiency of your heat treatment operation.
