Yoder Manufacturing of Cleveland, Ohio, has recently been contracted to supply a heavy wall, high strength four (4) roll weld box. Yoder has designed a new style weld squeeze box that consists of four (4) roll configuration. A top head roll assembly consisting of two (2) top edge rolls will control the edge presentation prior to welding. The head roll assembly has vertical adjust as a group and individual adjustments to compensate for improper strip edge alignment. The main squeeze pressure is provided by the bottom squeeze unit which will utilize two (2) side rolls only for rounds that range from 2.375” to 3.500” (60.3 to 88.9 mm) OD up to 75,000 PSI (517 MPa). This heavy wall weld box will be used primarily for producing the latest grades of premium API Pipe and Tubing products. The bottom squeeze roll assemblies are unique in that there is fast side close adjustment, as well as a fine tuned, gear compensated, close adjustment, thus eliminating the need for operators to utilize power tools, which can cause injury if they slip, as well as undue wear and excessive adjustment of the unit. All roll spindles are designed so the bearings are housed within the rolls. The welding area is the worst case scenario for temperature and wear in the tube mill, so this shaft-bearing arrangement yields the best possible bearing life for the weld box.
The weld box assembly has the ability to move up and downstream with respect to the tube mill flow. This allows the operator to fine tune the weld VEE angle with respect to the last fin-pass. Therefore, depending on your particular tooling design, the weld VEE angle can be changed to gain the best operating parameters for your particular product. The weld squeeze box assembly can handle up to wall thicknesses of 0.256” (6.5 mm).
