Characteristics of welding roller frame

Roller frame A device for rotating cylindrical (or conical) welds by means of friction between welds and automatic rollers. It is mainly used on a series of large machines in heavy industry.

 The welding roller frame is characterized by the application of pressure in the welding process without the addition of filler materials. Most pressure welding methods such as diffusion welding, high-frequency welding, cold pressure welding, etc., have no melting process, so there is no favorable alloying element burn like fusion welding, and harmful elements invade the weld, and the welding roller frame then simplifies the welding process, but also changes the welding health conditions.

 At the same time, because the heating temperature is lower than that of fusion welding and the heating time is shorter, the heat affected zone is small. Many materials that are difficult to weld with fusion welding can often be welded with pressure welding into joints of equal strength to the base material.

 Welding roller frame is a kind of welding equipment, in detail is a kind of welding roller frame, often used for the welding of the circular seam and the longitudinal seam inside the cylinder workpiece. Including base, automatic roller, driven roller, bracket, transmission device, power device drive and so on. The transmission device drives the automatic roller, and the friction between the automatic roller and the cylinder workpiece drives the workpiece to rotate and complete the displacement, which can complete the horizontal orientation welding of the ring seam and the longitudinal seam of the workpiece. The matching automatic welding equipment can complete the automatic welding, which can greatly increase the quality of the weld, reduce labor intensity and increase work efficiency. The welding roller frame can also be used for collaborative welding or as a device for detecting and installing cylinder body parts.

 It is mainly used for cylindrical installation and welding. If the spacing of the main and driven rollers is properly adjusted, the installation and welding of the vertebrae and the segment can also be carried out. For some non-round long welded parts, if they are mounted in the ring clamp, they can also be mounted on the welding roller frame. The welding roller frame can also cooperate with technology welding as a device for detecting and installing cylinder body parts. The application of welding roller frame can greatly increase the quality of weld, reduce labor intensity and increase work efficiency.
