“welded steel pipe” also known as straight seam welded pipe. Refers to the use of steel or steel plate bending deformation into a round, square and other shapes, and then welded into the surface of the joint of the steel pipe. The blanks used to weld steel pipes are steel plates or strip steel. “Welded…Details

Welding rotator is welding auxiliary equipment, specifically a welding turning rolls, commonly used in cylinder work piece outer circumferential and longitudinal seam welded both inside and outside. Consists of Base, driving wheel, driven wheel, frame, transmission device, power-driven device and so on. Gear driven active wheel, active wheel and cylinder friction between the work piece…Details
Surfacing methods in recent years there are two, one is using diameter φ 3.2-5mm flux-cored wire in automatic submerged arc welding under the burden, and the other is using φ 1.2-3.2mm self-shielded flux-cored wire for open arc welding. Sub-merged arc welding and Open arc welding compared, SAW welding flux shall be used after drying, in welding process shall constantly added flux, and needed hand removal welding slag, makes heap welding process human, and material input is big, and environment bad, for welding slag effect cannot against…Details
Application of automatic welding equipment With development of welding industry, people are not as simple as before for weld sturdy and now have more higher requirements, in addition to welding quality to meet the demand of consumers, the requirements of welding technology is becoming more and more high, so the traditional manual welding technology…Details
Welding equipment due to the possible tolerance pipe blank width and thickness, and the welding speed and welding temperature fluctuations, is likely to be involved in the change of welding pressure. Welding extrusion amount generally controlled by adjusting the distance between the squeezing roller, you can also use before and after the extrusion roll tube…Details
Welding steel beam adopts gantry automatic submerged arc welding. Beam connection plate ribbed plate adopts manual welding. Using gantry automatic welding shall meet the following two points: (1) After welding, within edge scope of 30-50mm, the rust, burrs, dirt and etc must be clean, in order to reduce welding defects such as porosity factor. (2)…Details
Traditionally, semi-automated welding has been done by fixing a welding torch at a set distance from a workpiece, then manually adjusting this relationship during welding to account for any variances in part geometry. This method of welding torch control works great for short duration welds or when the parts being welded have a high degree…Details
