Factors of weld defects
Factors of weld defects (1) Material factors: The so-called material factor refers welding base metals and welding materials used, such as wires, rods, flux, and the shielding gas and the like. All of these materials are directly involved in the welding puddle or physico-chemical reaction of the ...Read more -
Hot forging and cold forging
Hot forging means forging blank metal above the recrystallization temperature carried out. Features: reducing the deformation resistance of metals, thus reducing bad forging force needed to deform the material, so that greatly reduced the tonnage forging equipment; altering the structure of ingot...Read more -
Effect of steel composition on the zinc coating
When the meter steel workpieces, the selection of steel, usually the main consideration is: the mechanical properties (strength, toughness, etc.), processing performance and cost. But for galvanized parts, the composition of the selection of materials, the quality of the hot-dip galvanizing has g...Read more -
