FSW uses a drilling rotating tool to connect two parts without melting material. Heat generated from friction between the rotating tool and material surface, which leads to a softened region near the FSW tool. While the tool goes along the working line, it simultaneously connect two pieces of metal, and form integrated part by this procedures.
How does FSW work?
Step 1: The parts are clamped either edge to edge.
Step 2: The tool, which consists in a shoulder to heat the material by friction.
Step 3: the tool moves along the weld seam (constant speed of 700 to 3000 mm / min depending on the nature and thickness of the components). The heat generated by the friction makes the material softer and the tool stirs the parts together.
Step 4: At the end of the weld, the tool rises vertically leaving a hole
FSW features
● Low welding cost
● No material input
● No surface preparation
● No shielding gas,
● No gas equipment
● Reduction of post-welding inspection
We have the advanced FSW equipment, which provides a strong guarantee for the design of various custom-made radiators.
