What is welding pressure?


      Welding pressure is one of the main parameters of the welding process. After the two edges of the tube are heated to the welding temperature, the common metal grains are formed under the action of the extrusion force to crystallize each other. 

      The size of the welding pressure affects the strength and toughness of the weld. If the applied welding pressure is small, so that the edge of the metal welding can not be fully pressed, the weld of non-metallic inclusions due to small pressure is not easy to discharge, weld strength decreased, easy to crack after stress; pressure is too large, to welding Most of the temperature of the metal is extruded, not only to reduce the weld strength, but also produce inside and outside the burr too large or welding and other defects. Therefore, according to different varieties of specifications in practice to seek the best with the corresponding welding pressure.
