Product Information
"Excellent Welding Strength : Casing Rod&PIPE with Friction Welding"
Casing pipe is used to maintain the hole wall to the desired depth during the drilling, and several casing pipes are inserted to protect the internal space of the hole when you drill to the desired depth where the ground condition is not good (collapse layer).
*What is Friction Welding?"
The two workpieces are clamped to the friction welding machine. One is left fixed while the other is rotated at high speed, causing friction. Then, the friction surface becomes a state for bonding because of high heat (nearly 1,200℃). Then, the rotation is suddenly stopped and welded with pressure. It’s a brand-new solid state-bonding approach.
In conventional fusion welding, gas is mixed, generating bubbles in the weld joint. However, friction welding does not cause such defect because frictional heat and pressure are only used.
1. Casing pipe with Friction Welding
- Casing pipe is used to maintain the hole wall to the desired depth during the drilling, and several casing pipes are inserted to protect the internal space of the hole when you drill to the desired depth where the ground condition is not good (collapse layer).
2. The Five Great Advantages of Friction Welding
1)High-Quality bonding strength
Friction heat, vacuum, and instant pressure can bond the surface particles of both base materials thoroughly. The tensile strength of the friction welding joint is higher than that of each base metal. As shown in the photograph, the tensile strength test results in fracture at the base material, not at the joint. When the bending test of the friction welded joint is performed, it is confirmed that the welded portion is bent without being broken.
2)Possible to joint non-ferrous metals and dissimilar materials
3)High welding precision, productivity and environments friendly
Co2 welding, resistance welding, electron beam welding as well as homogeneous materials can be freely bonded to dissimilar metals and nonferrous metals, which are difficult in conventional welding methods. Momentary welding results in fewer heat impacts and little effect on the base material, and the productivity and welding quality are improved by the same working conditions. Environments frendly welding method becase not using welding rod but it rubs base metal and base metal.
In addition to the below specifications, We produce various size of Casing Pipe.
