XPERT XP9HI Welding & Brazing Torch
For HVAC technicians, it’s common to suddenly need welding during a job. In older welding devices, you had to carry an oxygen gas cylinder, a methane gas cylinder, a nozzle or torch, and hoses, which took up a lot of space. One of the toughest tasks is working at height, where the job becomes especially challenging. The XPERT XP9HI torch solves all these issues.
What is Hard Soldering?
In industry, hard soldering refers to a connection method in which the components being joined do not reach their melting point. Instead, the connection is made using a filler metal with a melting point higher than 450°C. This process creates capillary action between the metal and the joint, completing the hard soldering.
Important Tips for Soldering
Since the base metals (also known as Base Metal) do not reach their melting point, the joint area will always have a different composition than the base metals. To ensure capillary action, the gap between the metals should be as small as possible. To achieve the best mechanical and metallurgical properties from the joint, it’s essential to clean the area of rust, oxides, grease, paint, and any dirt. This is a requirement for welding, hard soldering, and soft soldering alike.
Benefits of Lower Heat in Soldering
The process occurs at a much lower temperature compared to welding, resulting in less heat entering the base metals. This minimizes metallurgical defects like grain size changes and physical issues such as warping. This method also allows for easy connection of dissimilar metals.
Soft Soldering
Soft soldering refers to a method where the base metals do not reach their melting point during the connection. However, the filler metal used melts, and the connection occurs through capillary action. In this case, the melting point of the filler metal is below 450°C.
